10.6.8 will not boot (MetaKine HandsOff)
This message started as a 'help I am in deep... trouble'. I've solved my problem and thought I'd share.
Anyone running MetaKine hands off will be well advised to update to 1.3.1 before attempting an install of 10.6.8: the old version causes a kernel panic and will not allow booting after an update. As it loads a kernel extension, safe mode also doesn't work.
Simple solution: boot OSX install DVD, run terminal from utilities menu
cd /Volumes/yournormalbootdisk/System/Library/Extensions
mv HandsOff.kext /
reboot
Then load Hands off app, and run the update it finds.
Apple, is it possible to check for such kexts before installing the update? I realise it's not your problem, but it was Apple I was cursing for an hour this morning when I couldn't remove my EFI password which had locked everything down!
MacBook Pro, Mac OS X (10.6.7), update to 10.6.8 with Hands Off
