This repository provides clear steps to manage and fix issues with Respondus LockDown Browser on macOS. Whether you use a recent Apple Silicon chip or the latest macOS update like Sequoia, this guide helps you resolve common error codes and permission blocks. You do not need technical skills to use these resources.
Respondus LockDown Browser acts as a secure container for online exams. Because it locks your system, it often conflicts with macOS privacy settings. Users frequently face issues where the app fails to launch or crashes during startup. This project documents these errors and provides fixes for Apple Silicon M1, M2, M3, and M4 processors.

Most users encounter errors because of stale background tasks. Try these fixes if the app stops working:
Force quit the application. Press Command + Option + Esc, select the browser, and click Force Quit. Reopen the application.
If you see an error code, note the number. Most codes relate to network proxies or screen sharing. Ensure no other applications like Zoom, Discord, or Teams run in the background. Close these apps before you start your exam.
If you use a beta version of macOS, you might face stability issues. This project tracks compatibility for Sequoia and Tahoe. Ensure your system remains on a public release to avoid unexpected closing of the browser.
This software monitors your screen, microphone, and webcam. Understand that the browser limits interaction with other apps to maintain academic integrity. If you have concerns about privacy, check the official documentation provided by your institution. This repository focuses only on getting the software to run on your Mac; it does not access your personal data or exam results.
Does this work on older Intel Macs? Yes, the steps provided apply to all macOS devices supported by the latest browser version.
Can I run this in a virtual machine? No. The browser detects virtual environments and prevents them from starting to protect the integrity of the testing environment.
How do I update the browser? Download the latest installer from the link above and run it. The new version overwrites the old one automatically.
