AREOS Posted May 30, 2012 Share Posted May 30, 2012 Just repair permissions cd /System/Library/Extensions/ sudo chmod -R 755 IO80211Family.kext sudo chown -R root:wheel IO80211Family.kext You can use Kextwizard to install your kexts to avoid this kind of problems Link to comment Share on other sites More sharing options...
