LockDown Browser Pre-Exam Checklist for Mac (2026 - Tested Procedure)

A 24-hour and 30-minute LDB pre-exam checklist for Mac. Catches the failures that cost students exams: TCC permission resets after macOS updates, blacklisted apps still running, dead webcam, dead battery. ~10 items spread across two windows.

24 hours before the exam

  1. Update macOS to the current minor. System Settings → General → Software Update. Don't do this 30 minutes before the exam - TCC dialogs may need re-approval after an update.
  2. Update LDB to the current build. Launch your installed LDB; it auto-checks on launch. Confirm version matches your university's required version.
  3. Run the practice exam. Most universities publish a no-credit practice exam in the same course. Run end-to-end including webcam check. Catches TCC failures + blacklist conflicts in advance.
  4. Verify camera + microphone work. Open FaceTime; both should work. If FaceTime sees you and hears you, Monitor will too.

1 hour before the exam

  1. Charge to 100%. Plan to take the exam plugged in if your laptop is > 2 years old or your exam is > 90 minutes.
  2. Close everything except LDB. Quit Slack, Teams, Zoom, Spotify, Discord, Grammarly desktop, Dropbox, OneDrive, Google Drive Desktop. Leave only macOS system processes + your LMS in Safari.
  3. Disconnect external monitors. Unplug HDMI, DisplayPort, USB-C-to-display, AirPlay, Sidecar. LDB blocks dual-monitor by default.
  4. Set Do Not Disturb. Control Center → Focus → Do Not Disturb until exam end time.
  5. Confirm Wi-Fi stable. Move closer to your router or wire up via Ethernet adapter. Cellular hotspot ready as backup.
  6. Use the bathroom. Most exams don't allow breaks; even those that do log it as a flagged event.

10 minutes before the exam

  1. Activity Monitor sweep. Search for: VNC, ARDAgent, screensharingd, TeamViewer, AnyDesk, Citrix, Parallels, VMware, UTM, Zoom, Teams. Quit each.
  2. System Settings → Privacy & Security. Confirm Camera, Microphone, Screen & System Audio Recording all show LockDown Browser with the toggle on. If Sequoia 15.3+ shows the 30-day re-prompt, click Allow now.
  3. Disable third-party antivirus real-time scanning (Malwarebytes, Bitdefender, Sophos). Re-enable after exam.
  4. Pause cloud sync. Dropbox menu → Pause; OneDrive → Pause syncing; Google Drive → Pause syncing.
  5. Clear desktop / quit FaceTime / quit Photo Booth. Anything that uses the camera.

2 minutes before the exam

  1. Open Safari, sign in to your LMS. Navigate to the exam. Don't click "Launch" yet.
  2. Position yourself. Camera at eye level, 18-24 inches from face. Light source in front, not behind. Plain background.
  3. Ready your student ID. Hold it 6-12 inches from camera, tilted to avoid glare.
  4. Click Launch. Allow LDB to open from the macOS prompt. Approve any TCC dialogs that appear.

Frequently asked questions

Should I restart my Mac before the exam?

Optional but recommended for high-stakes exams. A reboot resets every kernel extension, every TCC database lock, and every stuck process. Adds ~3 minutes to your prep window.

Can I take the exam on a public Wi-Fi (coffee shop, library)?

Technically yes, but adds risk: captive portals interrupt LDB's launch sequence, public networks have higher latency to Respondus, and you have no privacy from people behind you. Home Wi-Fi or wired Ethernet is safer.

My instructor said no breaks - what if I need to use the bathroom mid-exam?

Most LDB exams don't allow leaving the camera frame. Plan accordingly. If you have a documented medical need, request an accommodation with the disability office before the exam.
