OS X won't boot up unless I hold down option key
- by Gazzer
I have a strange issue on an early 2008 Mac Pro running OS 10.6:
if I restart the computer it restarts normally
if I shutdown and boot, it stops at the grey screen just before the boot process
if I shutdown and boot but hold down the option key, I can select the boot disk and all is good.
I've just cloned the disk, and the same thing happens.
