how do i install a .kext file?

1.extract the zip to your desktop (not into a folder, literally to your desktop) this means there should be a file on your desktop called AppleNForceATA.kext
2. open Terminal, (/applications/utilities/
3. type sudo -s in terminal then your admin password following this, now you should be root.
4. type sudo mv /users/(YOUR USERNAME)/desktop/AppleNForceATA.kext /system/library/extensions
at this point the file AppleNForceATA.kext should have dissapeared from the desktop,
5. type sudo chmod -R 755 /System/Library/Extensions/AppleNForceATA.kext
6. type sudo chown -R root:wheel /System/Library/Extensions/AppleNForceATA.kext
then go to /system/library and look for
Extensions.mkext, and also look for extensions.kextcache,

TRASH BOTH OF THESE (dont worry theyll come back on nxt boot.)

8. reboot and hope it works

  1. A good reason not to use KextHelper is when you need to install a Driver for your GPU and you have no GUI while doing it because your GPU is not supported. ;)

  2. I cannot get Kext helper to copy to a driveto run on a MAC system. My network driver is the issue so i cannot download to the machine i am trying to install.

  3. Your instructions just helped me recover a G5 with a failing drive that had decided to corrupt IOATAFamily.kext! Thanks!

  4. Sağol kardeşim. Ben de acaba ne oldu diye düşünüyordum. Meğersem tekrar kopyalayınca root tan çıkmış kullanma hakkı

  5. When I originally commented I seem to have clicked the -Notify me when new comments are added- checkbox and now every time a comment is added I recieve four emails with the same comment. Is there an easy method you can remove me from that service? Thank you!
