Hi,

gotta install IONetworkingFamily.kext, but dont know how. when i copy it into /System/Library/Extensions and reboot, i get an error saying that the extension wasnt installed properly. I red something like i have to set some permissions using chmod and chown, but i dont know how to set them (i know how to use the commands, but dont know for ex. to what do i have to chmod the kext in order to work).

Could anyone help me? Please, its quite urgent.

In terminal, simply type in


then reboot.

Nice try, but unfortunately it often doesn't get the job done.

for a catch-all solution to chmod & chown'ing new kexts, just try:

sudo chmod -R 755 /System/Library/Extensions && sudo chown -R root:wheel /System/Library/Extensions

yeah, ive figured out a way with repairing permissions with disk utility in the morning and it helped moi thanks anyway
