I'm trying to speed up a very sluggish imac and thought I'd run through applejack but if I hold down the shift key when restarting it gets stuck at the grey screen and I have to turn it off. It boots up normally otherwise. There's plenty of ram and hd space.
So what could be causing it to not want to start in single user mode.
