How to Uninstall LockDown Browser Completely from Mac (2026)
LockDown Browser stays installed after your exam ends. A drag-to-Trash uninstall leaves several hundred MB of state on your Mac - Application Support, Caches, LaunchAgents, Group Containers - that the next exam will reuse. Below: the complete removal procedure and the clean-reinstall path.
Files LDB writes to your Mac

~/Library/Group Containers/group.com.respondus.lockdownbrowser/ | 0 MB to several GB (Monitor buffer) |

~/Library/LaunchAgents/com.respondus.lockdownbrowser.plist (some MDM) | <10 KB |
~/Library/Saved Application State/com.respondus.lockdownbrowser.savedState/ | <1 MB |
Total disk reclaim from a complete uninstall: 200 MB to 5 GB depending on Monitor buffer accumulation.
