Expected Behavior

User should be able to choose camera in FaceTime to use. Even after I uninstall OBS i expect the OBS camera to be removed and not affecting any other applications. The only choice is to use OBS Virtual Camera.

Current Behavior

The OBS camera is still loaded after uninstall, it had completely overridden FaceTime from using any other camera - OBS Virtual Camera was the only option.

Steps to Reproduce

1. Install OBS
2. Grant all permissions
3. Uninstall
4. Follow camera uninstall guide: https://obsproject.com/kb/virtual-camera-troubleshooting
5. Delete sudo rm -rf /Library/CoreMediaIO/Plug-Ins/DAL/obs-mac-virtualcam.plugin

I followed several threads from other websites to try and remove and used CleanMyMac and this did not resolve the issue

Anything else we should know?

I have resolved the issue by deleting the plist file for FaceTime:

Go to finder and locate ~/Library/Preferences/com.apple.FaceTime.plist
Delete the com.apple.FaceTime.plist file
Empty Bin
Restart computer
Open FaceTime

It seems OBS is overriding all camera options in the preferences files when it is granted access.

I have shared this information incase anyone else comes across this problemm.

Start with the uninstall steps, the OBS plugin path /Library/CoreMediaIO/Plug-Ins/DAL/obs-mac-virtualcam.plugin, and the reported ~/Library/Preferences/com.apple.FaceTime.plist workaround. Reproduce on macOS 15 with OBS 31.0.2 and compare camera availability in FaceTime before and after uninstalling. Done means removing OBS no longer leaves OBS Virtual Camera as the only FaceTime option.
