LockDown Browser Exam Flow on Mac - Step-by-Step Walkthrough (2026)
A typical LockDown Browser exam on Mac follows a predictable shape: pre-launch system check, LMS authentication, kiosk-mode lockdown for the exam itself, and an exit dialog that re-enables the rest of macOS afterwards. Below: the full sequence, the surprises (Cmd-Tab is intercepted, the menu-bar clock is hidden, Wi-Fi drops are mostly recoverable), and the practical pre-exam checklist.
The launch sequence (minute-by-minute)
From clicking "Launch LockDown Browser" in your LMS to the first exam question:
- 0:00. Browser receives the launch URL with a custom
respondus-lockdown://scheme. macOS prompts "Open LockDown Browser?" - click Open. - 0:01-0:03. LDB launches, takes over the screen, shows welcome screen.
- 0:03-0:05. Process blacklist scan. If anything blacklisted is running, you get a "Close these applications" dialog.
- 0:05-0:08. Webcam check (Monitor only).
- 0:08-0:10. ID photo (Monitor only).
- 0:10-0:14. Environment scan (Monitor only).
- 0:14-0:15. Exam password (if instructor set one).
- 0:15+. Exam starts. Timer begins. Kiosk mode active.
Total pre-exam overhead: ~15 minutes when Respondus Monitor is enabled, ~3 minutes without it.
