How to Manually Install Kernel Extensions in Mac OS X
Can’t use the easy Kext Drop app for some reason to install a kernel extension? Installing kexts (kernel extensions) manually is always an option and it’s not too difficult if you’re comfortable with the command line:
- Copy the .kext file(s) to /System/Library/Extensions/
- Open the Terminal and type:
- Type the following commands at the terminal, replacing the kext name with the one you are installing
- Now remove the kext caches:
- Reboot the Mac
sudo chmod -R 755 kextfile.kext
sudo chown -R root:wheel kextfile.kext
sudo rm -R Extensions.kextcache
sudo rm -R Extensions.mkext
The kernel extension should now be installed.
As you can see this is more time consuming than the alternative, so ideally you’ll just one of the installer applications instead.
