Unable to uninstall Microsoft's Keyboard Drivers in Mac

Solution 1:

There should be an uninstaller application in your Utilities folder (/Applications/Utilities/) called either IntelliPoint UnInstaller.app or IntelliType UnInstaller.app

If those are not available, the extensions are saved in /System/Library/Extensions - namely MicrosoftMouse.kext and MicrosoftKeyboard.kext. In order to safely remove these you will want to run the commands:

sudo kextunload /System/Library/Extensions/MicrosoftMouse.kext
sudo kextunload /System/Library/Extenstions/MicrosoftKeyboard.kext

before dragging the files to your trash. If you don't it may not allow you to delete them until you restart.

Lastly, under /Library/Keyboard Layouts there may be a file called Microsoft Keyboards.bundle you can drag to the trash and delete as well.

kextunload stands for kernel extension unload.
