How to Install LockDown Browser from D2L Brightspace on Mac

Last updated 2026-05-02 · LDBypass Editorial

D2L Brightspace integrates LockDown Browser at the quiz level. From your course, navigate to Quizzes, click the specific quiz that requires LDB, and click "Start Quiz". The launch dialog shows the LDB download link if you don't have it installed.

Step-by-step path on D2L Brightspace

Sign in to your D2L Brightspace instance (typically [your-school].brightspace.com or brightspace.[your-school].edu).
Click the course in the My Courses panel.
In the course navbar, click "Quizzes".
Click the specific quiz that requires LDB.
Click "Start Quiz". The launch dialog appears with the LDB requirement notice.
Click "Download LockDown Browser" if you don't have it installed. Browser downloads the .dmg.
Proceed with the standard macOS install steps.

If the download link is missing

If your D2L Brightspace course doesn't show the LDB download link where this guide says it should be, the most likely causes:

Your instructor hasn't enabled LDB for that specific assessment yet.
The assessment is in test/draft mode, not published.
Your enrollment in the course hasn't fully synced (try signing out and back into the LMS).
D2L Brightspace is in maintenance window (rare).

Email your instructor with: the course name, the specific assessment, and a screenshot of what you see. They can fix the configuration server-side or send you the link directly.

After download - install on macOS

Open Finder → Downloads. Double-click the .dmg.
macOS verifies the notarisation. ~2-5 seconds.
The .dmg mounts. Double-click the installer package.
Authenticate with admin password (Sonoma 14.4+ requires this).
Installer runs ~10-30 seconds. LockDown Browser.app appears in /Applications.
Eject the .dmg from Finder.
Return to D2L Brightspace, click "Launch LockDown Browser" on the assessment.
macOS prompts: "Open LockDown Browser?" → Open.
Approve Camera + Microphone + Screen Recording TCC dialogs.
The exam begins.

Upgrade path (if LDB is already installed)

If you already have LDB installed from a previous course, you may not need to reinstall. Launch your existing LDB; it auto-checks for updates. Confirm the version matches your university's required minimum (right-click LDB.app → Get Info).

If your installed LDB is older than the Dashboard requires, you'll see error -111 at launch. Reinstall from your D2L Brightspace link to get the current build.

Frequently asked questions

Does D2L Brightspace require a different LDB build than Canvas or Blackboard?

No - LDB binds to your institution's Respondus Dashboard, not to a specific LMS. The same LDB install handles Canvas, Blackboard, D2L, and Moodle if your university uses multiple LMSes.

My D2L course shows "Quizzes" but no LDB-required quizzes.

Your instructor hasn't enabled LDB for that course yet, or the LDB-required quiz is in a different location (Activities, Assessments, etc.). Check the course menu for similar tabs.
