Uninstall OS X extensions, additional audio devices (drivers)

A lot of third-party audio/video app (Screen recording apps) will install the additional audio device in the system preference panel.

To list all third party kernel extensions in Mac OS X:

In terminal:

kextstat | grep -v com.apple

To uninstall the extension:

sudo kextunload -b NAME_OF_THE_EXTENSION
e.g. sudo kextunload -b com.globaldelight.driver.Boom2Device

 

If we want to manually install an extension:

    1. Copy the .kext file(s) to /System/Library/Extensions/
    2. Open the Terminal and type:
    3. cd /System/Library/Extensions/
    4. Type the following commands at the terminal, replacing the kext name with the one you are installing

sudo chmod -R 755 kextfile.kext
sudo chown -R root:wheel kextfile.kext

5. Now remove the kext caches:

sudo rm -R Extensions.kextcache
sudo rm -R Extensions.mkext

6. Reboot the Mac
