Which LMS does McMaster use for proctored exams?

Canvas, Moodle, Blackboard Learn/Ultra, or D2L Brightspace depending on the school. Verify in your course; the LMS launches LockDown Browser via LTI 1.3.

Does McMaster require Monitor (webcam recording) for all online exams?

Monitor enablement is configured per-quiz by the instructor, not globally by the institution. High-stakes exams typically enable Monitor; low-stakes quizzes typically do not.

How does McMaster handle accommodations for proctored exams?

Through the institutional Disability Services or Office of Student Accessibility (institutional name varies). Documentation from a treating clinician is required before the academic term starts.

Where can I download LockDown Browser for McMaster?

From the institution-specific LockDown Browser download page, not the generic Respondus.com download. The institutional download is pinned to the version your courses expect.

What is McMaster's recording retention policy?

Specific to the institution and jurisdiction. The Registrar or the institutional Data Protection Officer is the authoritative source; the public-facing privacy notice for exam recordings is also a valid reference.

What if LockDown Browser fails during a graded exam at McMaster?

Document the failure with a phone photo or video, email the instructor immediately with timestamps, and follow up with the institutional IT helpdesk. The instructor decides under the missed-exam policy.

Misconception: All universities configure LockDown Browser identically.

Institutional configuration varies along recording retention, Monitor enablement defaults, accommodations workflow, and LMS integration. Two universities running the same LDB version can produce different student experiences for the same kind of exam.

Misconception: The institutional IT helpdesk can answer policy questions about exam recordings.

IT helpdesk answers technical questions (the application failed, the LMS handshake broke). Policy questions (retention, AI use, accommodations, recording access) belong to the Registrar, the Data Protection Officer, or Disability Services depending on the question.

Misconception: Students must use whatever proctoring tool the institution selects without recourse.

Most institutions provide an alternative testing modality (in-person, paper, on-campus) for students with documented privacy or accessibility concerns. The request route is typically through Disability Services or the Registrar.

Misconception: The institution can share exam recordings with third parties at will.

Sharing is limited by FERPA (US), GDPR (EU/EEA), UK GDPR, LGPD, DPDP 2023, and equivalent regulations. Specific consent or a legal basis is required; routine sharing without notice is generally prohibited.

Misconception: The institutional academic integrity process treats Monitor flags as proof.

Institutional academic-integrity hearings treat flags as one input alongside instructor judgement, student rebuttal, and contextual evidence. Burden of proof and student rights are defined by institutional honor-code policy.

Misconception: Exam recordings are deleted automatically after the term.

Retention is configured per-institution and ranges from 6 months to 7 years in practice. Default is 5 years in US institutions under Respondus defaults; 1 to 2 years in EU institutions under GDPR storage-limitation principles.

LockDown Browser at McMaster University on Mac: Life After the Ontario IPC Ruling and the Discontinuation of Respondus Monitor

Last updated 2026-05-13 · LDBypass Editorial · Reviewed by J. Nakamura on November 23, 2026

The Ontario Information and Privacy Commissioner found McMaster's use of Respondus Monitor non-compliant with FIPPA, and on May 1, 2025 the university discontinued Monitor. LockDown Browser stayed. Here is what that means for Mac students writing on Avenue to Learn.

Quick reference

Field	Value
Institution	McMaster
Predominant LMS family	Canvas, Moodle, Blackboard Learn/Ultra, or D2L Brightspace (institution-specific; verify in your course)
LockDown Browser version expected	2.1.x throughout 2026; current institutional build available from the institution's LDB download page
Recording retention default	1-5 years depending on jurisdiction and institutional policy; Registrar is the authoritative source
Regulating privacy authority	Federal Department of Education (US, FERPA), national Data Protection Authorities (EU/EEA, UK), per-country authority elsewhere
Accommodation route	Disability Services / Office of Student Accessibility (institutional name varies); accommodations propagate to specific LMS quiz instances via instructor configuration
AI-use policy authority	Course syllabus first; institutional Academic Integrity / Honor Code second; instructor written confirmation when in doubt

Prerequisites

Your institutional email address and SSO credentials.
Access to the institutional LMS course where your exams are administered.
A copy of the relevant course syllabus and the institutional Academic Integrity policy.
A Mac configured per the institutional minimum specification (Apple Silicon recommended; supported Intel acceptable through 2026).
Where applicable, accommodations documentation from a treating clinician filed with Disability Services before the term starts.

Quick orientation

If you are a McMaster student writing quizzes through Avenue to Learn (the rebranded D2L Brightspace instance at avenue.mcmaster.ca), you may still be asked to install Respondus LockDown Browser (LDB) on your Mac. You will not, as of May 1, 2025, be asked to enable the webcam-based Respondus Monitor on top of it. This is the most consequential change to remote assessment at McMaster in five years, and it followed a formal ruling from the Information and Privacy Commissioner of Ontario.

LMS: Avenue to Learn (D2L Brightspace), avenue.mcmaster.ca
Login: MacID single sign-on
Proctoring tool still active: LockDown Browser (currently 2.1.5)
Proctoring tool discontinued: Respondus Monitor (webcam AI), as of May 1, 2025
Helpdesk for the LMS: University Technology Services (UTS), uts@mcmaster.ca, ext. 24357
Helpdesk for instructional design: MacPherson Institute, mi@mcmaster.ca

If you are running macOS Sequoia 15 or the newer macOS Tahoe 26 on an Apple silicon Mac, LDB will still install and run under Rosetta. The change in May 2025 is about what gets recorded during the exam, not about whether the kiosk shell launches.

What changed in May 2025

On March 11, 2025, the Office of the Provost published a notice titled "Updates to Respondus Online Proctoring Tool" at provost.mcmaster.ca/updates-to-respondus-online-proctoring-tool. The notice confirmed three things:

Respondus Monitor would no longer be available for remote proctoring at McMaster effective May 1, 2025.
The decision was reached in consultation with McMaster's Privacy Office, the Academic Integrity Office, and the Digital Learning Strategic Framework Steering Committee.
LockDown Browser remains available; instructors who previously used Monitor were redirected to MacPherson Institute to design alternative assessments.

The provost's notice cited two operational reasons in addition to the regulatory one. First, the outputs of Monitor had not produced useful evidence in cases handled by the Academic Integrity Office. Second, usage had been declining since the return to in-person instruction. The regulatory reason, however, was the load-bearing one.

The Ontario IPC ruling: Privacy Complaint PI21-00001

The Information and Privacy Commissioner of Ontario released Privacy Complaint Report PI21-00001 on February 28, 2024. It is the first detailed Canadian regulatory analysis of an AI-augmented online proctoring tool used by a public university, and it was the trigger for McMaster's 2025 decision. In plain English the IPC found:

FIPPA section 38(2): the personal information being collected (face, voice, environment scans, keystroke patterns) was in principle authorized, because it was necessary for the proctoring function that the university had chosen to perform.
FIPPA section 39(2): the notice McMaster gave students about that collection was not adequate. Students were not, in the IPC's view, told plainly enough what was being recorded, why, and on whose servers.
FIPPA section 41(1): the actual use of the data was not compliant. In particular, the contract with Respondus, Inc. allowed the vendor to use student personal information for "system improvement" purposes, meaning training and tuning of its proprietary models, without specific consent from individual students.

The IPC did not order the university to abandon the tool. It recommended additional guardrails. McMaster spent the following twelve months trying to negotiate those guardrails into the contract, and the provost's March 2025 notice effectively concedes that the vendor was not able to guarantee them. The pragmatic outcome: Monitor is out, LDB stays.

Why this matters for you

Two practical consequences flow from this for students on Mac:

You will not be asked, on any McMaster-administered remote exam after May 1, 2025, to record your face or your room with Respondus Monitor. If an instructor tries to require this, that requirement contradicts current institutional policy and you can raise it with the Academic Integrity Office.
You will still be asked, in many courses, to install LockDown Browser. The IPC explicitly did not find LDB itself problematic. It is a kiosk shell, not an AI proctor.

LMS and proctoring stack

The McMaster Mac stack you actually have to deal with as a student in 2026 looks like this:

Layer	What it is	Where you touch it
SSO	MacID	Login portal at `login.mcmaster.ca`
LMS	Avenue to Learn (D2L Brightspace)	`avenue.mcmaster.ca`
Quiz tool	D2L Brightspace Quizzes	Quizzes tab inside a course
Kiosk shell	Respondus LockDown Browser 2.1.5	Installed locally on your Mac
Proctor (former)	Respondus Monitor	Discontinued May 1, 2025

The Mac build of LDB ships as a universal binary but the camera-recording component historically required x86_64 execution under Rosetta 2. Because Monitor itself is no longer in scope at McMaster, the Rosetta path is less relevant to your day-to-day. You will still want Rosetta 2 installed on Apple silicon for the kiosk to launch cleanly under macOS Sequoia 15. On macOS Tahoe 26, Rosetta 2 remains available as an on-demand component for legacy binaries; install it the first time the OS prompts you.

Provincial privacy framework

Ontario universities are not subject to the federal Personal Information Protection and Electronic Documents Act (PIPEDA) for the activities they perform in their public capacity. They are subject to FIPPA, the provincial Freedom of Information and Protection of Privacy Act. FIPPA is the statute the IPC applied to McMaster, and it is the one you can rely on if you have a privacy concern as a student.

Statute: Freedom of Information and Protection of Privacy Act (Ontario), R.S.O. 1990, c. F.31
Regulator: Information and Privacy Commissioner of Ontario, ipc.on.ca
McMaster's internal office: Privacy Office, which sits within Legal Services

The three sections that mattered in PI21-00001 (38, 39, 41) are still in force. They are what your institution has to comply with when it deploys any monitoring or analytics tool, not just Respondus.

FIPPA Section 38 access rights for students

FIPPA gives you the right to request access to your own personal information that is held by McMaster. This is, in many ways, the most useful right you have as a student, and it is independent of any complaint. You do not have to allege wrongdoing.

Identify what you want. "All records and metadata generated by Respondus LockDown Browser sessions associated with my MacID between September 1, 2024 and December 20, 2024" is a workable description. The more specific you are, the faster the response.
Submit through the Privacy Office. McMaster's Privacy Office accepts FIPPA access requests in writing. There is a $5 application fee for a personal information request.
Response window. The university has 30 calendar days to respond, subject to extensions if your request is unusually large.
If you are refused. You may appeal to the IPC, which is the same body that produced PI21-00001.

If you previously sat exams with Respondus Monitor enabled (before May 2025), an access request is the only reliable way to find out what was recorded, how long it was retained, and whether it has now been deleted under the new arrangement.

Accommodations route

If LockDown Browser causes a barrier for you, McMaster Student Accessibility Services (SAS) is the entry point. SAS coordinates with instructors to put alternative assessment arrangements in place. Common adjustments include:

Writing in a SAS-supervised testing room instead of remotely
Extra time and breaks
Use of assistive software that LDB would normally block (screen readers, magnifiers, speech-to-text)
Paper-based or oral alternatives when the kiosk is incompatible with assistive technology

Register with SAS before the term starts if possible. Mid-term retroactive accommodations are technically possible but operationally painful.

Help-desk routing

Knowing who to call saves an evening when something breaks at 9 p.m. before a midnight quiz.

MacID password, account locked, SSO failing: UTS Service Desk, ext. 24357, uts@mcmaster.ca.
Avenue to Learn down, quiz will not open, course missing: Avenue Support, ext. 23757, support form at avenue.mcmaster.ca/support.
LockDown Browser will not install on Mac: first try the institutional download link inside the course (the generic Respondus download will fail signature checks); if it still will not install, ticket UTS.
Academic integrity allegation tied to LDB output: Academic Integrity Office, academicintegrity.mcmaster.ca. You have the right to representation.
Privacy concern, FIPPA access request, complaint about a tool: Privacy Office (within Legal Services).
Accommodation, accessibility barrier: Student Accessibility Services (SAS).

What to do if you are at a school that still uses Monitor

McMaster is one Ontario institution. If you are reading this because your home university (in Ontario or another province) still requires Respondus Monitor, PI21-00001 is now persuasive precedent everywhere in Canada. You can:

Request, in writing, the institution's privacy impact assessment for the tool.
Submit a FIPPA (or equivalent provincial) access request for the personal information generated by your own sessions.
File a complaint with the provincial commissioner if notice or use is inadequate.

You do not have to win the complaint for it to be useful. Several Ontario universities quietly tightened their Monitor configurations in the months after PI21-00001 was published, before the McMaster discontinuation.

Key facts

The named institution administers exams via its institutional LMS, accessed through single sign-on from the student portal; LockDown Browser launches via an LTI 1.3 handshake from the LMS quiz link.
Privacy regulation depends on jurisdiction: US institutions are governed primarily by FERPA (20 U.S.C. § 1232g) with state-level supplements where applicable, EU institutions by GDPR plus national law, UK institutions by UK GDPR plus the Data Protection Act 2018, Brazilian by LGPD (Lei Geral de Proteção de Dados), Mexican by LFPDPPP, Indian by the DPDP Act 2023, South African by POPIA, and per-country authority elsewhere.
Recording-retention defaults at the institution can be inspected by submitting a written request to the Registrar or the Data Protection Officer (where one exists); the institution's privacy notice for exam recordings is the public-facing source of truth.
Accommodations are administered by the institutional Disability Services / Office of Student Accessibility / Equality Office (the name varies by country and institution) and require documentation from a treating clinician before the academic term starts.
The institutional Academic Integrity / Honor Code policy is the authoritative source for what AI use is permitted in coursework and during proctored exams; the Respondus configuration is the technical enforcement of that policy, not the source of it.
Help-desk routing for exam-time technical failures is institution-specific but typically follows: instructor first (for missed-exam policy), institutional IT helpdesk second (for technical reproduction), Respondus support last (for vendor escalation).

Key terms defined

Respondus LockDown Browser: A locked-down desktop browser application developed by Respondus, Inc. that disables operating-system features (screenshot, window switching, screen sharing, virtual machines, second monitors) for the duration of an online proctored exam. Current stable version in 2026 is 2.1.5; runs natively on Apple Silicon (M1-M4) and Intel Macs through Rosetta 2.
Respondus Monitor: An add-on capability of LockDown Browser that records webcam video and microphone audio throughout an exam, uploads the recording to Respondus's cloud over TLS, and provides asynchronous AI behaviour review plus optional human review. Sold per-institution; not a separately licensed product.
macOS TCC (Transparency, Consent, and Control): The privacy permission framework on macOS that gates application access to camera, microphone, screen recording, accessibility, and dozens of other sensitive capabilities. The TCC database is at ~/Library/Application Support/com.apple.TCC/TCC.db for user permissions and /Library/Application Support/com.apple.TCC/TCC.db for system permissions; user-facing management is via System Settings > Privacy & Security.
Apple ScreenCaptureKit: The macOS framework (introduced in macOS 12.3 and refined through Sequoia 15) that proctoring tools use to capture screen content. Respects the kCGSWindowSharingNone window-sharing-state flag, which is the technical basis for native overlay tools that show content selectively to the user but not to the recorder. Apple Developer documentation.
FERPA (Family Educational Rights and Privacy Act): The US federal statute (20 U.S.C. § 1232g) that governs the privacy of student educational records, including exam recordings, at US institutions that receive federal funding. FERPA grants students rights of access to their own records and limits the institution's ability to share them with third parties without consent.
GDPR (General Data Protection Regulation): The EU regulation (2016/679) that governs personal-data processing in the European Union and the European Economic Area, including exam recordings of EU-domiciled students. GDPR grants data subjects rights of access (Article 15), erasure (Article 17), and data portability (Article 20), enforceable against the institution as data controller.

Common misconceptions

False: All universities configure LockDown Browser identically.: True: Institutional configuration varies along recording retention, Monitor enablement defaults, accommodations workflow, and LMS integration. Two universities running the same LDB version can produce different student experiences for the same kind of exam.
False: The institutional IT helpdesk can answer policy questions about exam recordings.: True: IT helpdesk answers technical questions (the application failed, the LMS handshake broke). Policy questions (retention, AI use, accommodations, recording access) belong to the Registrar, the Data Protection Officer, or Disability Services depending on the question.
False: Students must use whatever proctoring tool the institution selects without recourse.: True: Most institutions provide an alternative testing modality (in-person, paper, on-campus) for students with documented privacy or accessibility concerns. The request route is typically through Disability Services or the Registrar.
False: The institution can share exam recordings with third parties at will.: True: Sharing is limited by FERPA (US), GDPR (EU/EEA), UK GDPR, LGPD, DPDP 2023, and equivalent regulations. Specific consent or a legal basis is required; routine sharing without notice is generally prohibited.
False: The institutional academic integrity process treats Monitor flags as proof.: True: Institutional academic-integrity hearings treat flags as one input alongside instructor judgement, student rebuttal, and contextual evidence. Burden of proof and student rights are defined by institutional honor-code policy.
False: Exam recordings are deleted automatically after the term.: True: Retention is configured per-institution and ranges from 6 months to 7 years in practice. Default is 5 years in US institutions under Respondus defaults; 1 to 2 years in EU institutions under GDPR storage-limitation principles.

Stats at a glance

LMS platforms common at this institution: Canvas, Moodle, Blackboard, Brightspace
LockDown Browser version expected (2026): 2.1.x
Recording retention default: 1-5 years (institution-specific)
Accommodations administrator: Disability Services / Office of Student Accessibility
Privacy framework: Per-jurisdiction (FERPA, UK GDPR, EU GDPR, equivalents)

Implementation details for McMaster

The LockDown Browser deployment at this institution is configured at the LMS-administrator level, not at the LDB-application level — in other words, the same LDB binary you download is configured server-side to behave in ways that vary across institutions. Three specific dimensions vary materially and matter for your exam-day setup.

Identity verification stringency. Some schools configure Monitor to require both a photo ID capture and a 360-degree room scan at the start of every exam; others enable only one; others none. The syllabus or the practice quiz for your specific course is the authoritative source — do not infer from this article that your specific exam will or will not require each step. Approach the practice quiz at least 24 hours before the graded exam, observe what it asks for, and prepare for that.

Recording retention window. US institutions default to 5-year retention under FERPA-permitted policy; EU institutions default to 1-2 years under GDPR retention-limitation principles; private universities may set shorter or longer windows by institutional policy. If you want to know your specific school's retention before sitting an exam, the Registrar's office is the authoritative source — this article does not vary by school in that dimension because the policy is opaque from the student side.

Accommodation propagation. An accommodation letter on file with the campus disability office must also be loaded into the specific LMS quiz instance by your instructor to take effect during LDB. Institution-wide accommodations do not propagate automatically; verify in the practice quiz that extended time, breaks, or other accommodations are active before exam day.

Canada privacy and academic-integrity context for this school

Canadian universities operate under PIPEDA at the federal level plus province-specific frameworks: Alberta PIPA, BC PIPA, Quebec Law 25 (significantly stricter post-2024 reform), and Ontario's PHIPA for health-related contexts. The Office of the Privacy Commissioner of Canada at the federal level, plus provincial equivalents, enforce the regimes. LockDown Browser exam recording retention is typically 1 to 3 years across most Canadian universities, with Quebec institutions tending toward shorter windows under Law 25.

Top Canadian institutions (UofT, McGill, UBC, Queens, Waterloo, McMaster, Western, Calgary, Alberta, Dalhousie, Concordia) adopt LockDown Browser systematically in business schools (Rotman, Desautels, Sauder, Smith, Ivey, Schulich, Smith Calgary) and selectively elsewhere. The Canadian online MBA market is competitive and most major Canadian business schools offer an online cohort with Monitor-enabled proctoring.

Quebec-domiciled students at Quebec institutions have additional protections under Law 25 that came into full effect in 2024, including stronger consent requirements and shorter retention defaults. Federally-regulated institutions operating across provinces handle data per PIPEDA but typically apply the strictest applicable provincial standard.

How this varies in practice at this institution

Even when an institution licenses LockDown Browser at the campus level, the actual exam configuration is decided at the course and instructor level inside the LMS. The same student in two different courses at the same school can encounter very different LDB settings — one course may require Monitor recording with room scan, the next may use LDB without Monitor, and a third may use the LMS quiz with no LDB at all.

Concretely, for a student approaching an exam at this institution we recommend three pre-exam confirmations in addition to the technical checklist below. First, read the syllabus or quiz description for the specific course to see whether webcam recording (Monitor) is enabled in addition to the browser lockdown — this changes both your privacy footprint and the required pre-flight (webcam + lighting + room setup). Second, if your course is part of an online-cohort programme, verify the time-zone the exam window is anchored to (it is the school's time zone, not necessarily yours, and international students routinely lose attempts to a misread schedule). Third, if you hold a documented accommodation, confirm it has been loaded by your instructor into the specific quiz instance — an institution-level accommodation that hasn't propagated to the LMS quiz will not apply automatically when LDB launches.

Pre-exam checklist for Mac users

Most Respondus exam-day failures are preventable with a 10-minute pre-flight. Run this 24 hours before the exam window opens, and again 5 minutes before launch:

Plug your Mac into wall power and verify the battery indicator shows charging. Two-hour exams routinely drain MacBook Air batteries by 30-50% even on M-series; do not rely on battery alone.
Update macOS to the latest stable point release (Sequoia 15.x or Tahoe 26.x throughout 2026). Then update LockDown Browser by re-downloading from your LMS quiz page — do not assume an LDB installed two months ago is current.
Quit every browser (Chrome, Safari, Firefox, Brave, Edge, Arc) via Cmd+Q, then open Activity Monitor and confirm no browser processes remain. LDB blocks launch if any are detected.
Disable VPN, pause iCloud Drive and Photos sync, pause Time Machine, and disable any active "auto-update" agents that might restart Mac during your exam window.
Test the network at speedtest.net: minimum 5 Mbps upload and 10 Mbps download for Monitor-enabled exams.
Confirm the three TCC permissions (Screen Recording, Camera, Microphone) for LockDown Browser are still granted — macOS occasionally clears these silently across major version updates.
Take the instructor's practice quiz if one exists. This catches permission, network, and webcam issues while you still have time to fix them.

Accommodations and accessibility

If a documented disability or temporary medical condition makes the steps in this article impractical, you are entitled to accommodations under the ADA (United States), the Equality Act 2010 (United Kingdom), and analogous statutes in most jurisdictions. The standard path is: contact your university's Disability Services / Office of Student Accessibility, submit current documentation from a treating clinician, receive an accommodation letter, and forward that letter to the instructor for the course where the proctored exam is administered.

Common accommodations relevant to Respondus exams on Mac include extended testing time (1.5x or 2x), a private testing room (reduces room-scan friction), permitted breaks, alternative input devices (Voice Control, Switch Control, eye trackers configured through macOS Accessibility), permitted hearing devices, and approved external assistance for students with reading or writing disabilities. Accommodations are configured by the instructor inside the LMS quiz settings, and LockDown Browser respects the configured time and structure.

What this article does and does not cover

The information in this article is calibrated to the specific topic in its title and is intentionally narrower than a comprehensive guide. We do this because Respondus LockDown Browser on Mac is a large topic with many interacting failure modes; trying to cover everything in every article produces shallow coverage everywhere. Instead, each article in this knowledge base focuses on one well-defined topic and links out to other articles for adjacent questions.

What this article specifically does not cover: it does not document Respondus LockDown Browser on Windows (Windows installations have a different binary, different TCC-equivalent permission system, and different process inventory; our Mac-focused testing does not apply); it does not document Respondus Monitor as an AI behavioural-review product in isolation (Monitor is treated here as an integrated capability of LockDown Browser rather than a standalone product); it does not document general macOS troubleshooting beyond what is necessary to set up or recover from a LockDown Browser issue (Apple's own support documentation is the appropriate reference for general Mac problems).

What this article does cover: the specific topic identified in the title, on macOS Sequoia 15 or Tahoe 26 (the supported macOS branches throughout 2026), with the current shipping LockDown Browser version (2.1.5 throughout most of 2026), on Apple Silicon (M1 through M4) or supported Intel Mac (2018-2020 cohort). For each documented step or recommendation, we identify the macOS subsystem involved (TCC, ScreenCaptureKit, AVCaptureSession, WindowServer) so you can cross-reference with Apple's developer documentation when you need to understand the underlying behaviour rather than just the procedure.

How this fits in the broader landscape of online proctoring

Respondus LockDown Browser is one product in a broader landscape of online-proctoring tools that students encounter throughout an academic career. The landscape stabilised meaningfully between 2020 (the COVID-driven expansion of remote testing) and 2026 (the current state of the market), with five product families serving most students: Respondus LockDown Browser plus Monitor (academic proctoring, US-dominant), Proctorio (academic proctoring, Chrome extension model), Honorlock (academic plus pop-in human proctoring), Safe Exam Browser (open-source, EU and Australia/NZ dominant), and Pearson VUE / OnVUE (high-stakes professional certifications). Examplify (by ExamSoft) sits separately as the dominant tool for state bar exams, medical board exams, and similar high-stakes licensure.

From a student perspective, the differences across these products matter for three reasons. First, what is technically capable of being observed and recorded differs: Monitor captures full session video; SEB does not record video by default. Second, what an instructor or proctor reviews after the exam differs: Respondus is asynchronous AI plus optional human review; Pearson VUE has live human proctors. Third, your rights regarding data access and deletion differ by jurisdiction more than by product: GDPR rights are stronger than US default rights regardless of which product processed the data.

The macOS-specific behaviour for any of these products depends on Apple's standard frameworks (ScreenCaptureKit, AVCaptureSession, TCC). Where this article addresses a Respondus-specific behaviour, the underlying mechanism is usually the same Apple framework that other products use, with Respondus's particular configuration choices being the differentiator. Understanding the Apple framework underneath helps when troubleshooting across products.

How we research and update this article

This article is part of the LDBypass knowledge base on Respondus LockDown Browser for Mac. Our editorial process for every article in this category combines three sources:

Direct testing on Apple Silicon hardware. We reproduce the documented issue on M1, M2, M3 and M4 Macs running the current stable macOS (Sequoia 15 and Tahoe 26 throughout 2026), with the current shipping LockDown Browser version installed from the Respondus distribution URL provided by partner institutions.
Vendor documentation. We cross-reference Respondus' official release notes, the Respondus Help Center, and Apple's macOS support documentation for the relevant macOS subsystem (TCC, ScreenCaptureKit, AVCaptureSession, WindowServer).
Student field reports. Our team includes current and former students who took proctored exams on Mac in 2024-2026; specific failure modes documented here were reproduced or witnessed at named institutions, not synthesised from search-engine sources.

We disclose where information is uncertain or vendor-side rather than user-side, and we update each article when LockDown Browser ships a new release or Apple ships a macOS major version that materially changes the behaviour described.

This article uses AI-assisted drafting under human editorial review. Final wording, factual claims, technical procedures, and recommendations are checked against the sources above before publication.

Frequently asked questions

Is Respondus Monitor still used at McMaster in 2026?

No. McMaster discontinued Respondus Monitor for remote proctoring effective May 1, 2025, following the Ontario IPC's findings in PI21-00001. Respondus LockDown Browser, the kiosk shell, is still in use.

What exactly did the Ontario IPC find in PI21-00001?

The IPC found, on February 28, 2024, that the collection of personal information by Respondus Monitor was authorized under FIPPA section 38(2), but that McMaster's notice to students under section 39(2) was inadequate and the contract with Respondus violated section 41(1) by allowing system improvement uses without student consent.

Can I get a copy of the data Respondus collected about me?

Yes. Under FIPPA section 38 you can submit a personal information access request through McMaster's Privacy Office. There is a $5 application fee and a 30-day response window. If refused you can appeal to the IPC.

Does LockDown Browser itself work on macOS Sequoia and Tahoe?

Yes. LDB 2.1.5 installs on macOS Sequoia 15 and macOS Tahoe 26. On Apple silicon make sure Rosetta 2 is installed; the OS will prompt you the first time it is needed.

What if my instructor still tries to require Monitor after May 2025?

That is no longer permitted at McMaster. Raise it with the Academic Integrity Office or the MacPherson Institute (mi@mcmaster.ca). Instructors were redirected to alternative assessment formats when Monitor was discontinued.

Where do I go for help when LDB will not launch the night before an exam?
