Mac Pro, Lion won't boot
I've tried everything, short of lugging it to an Apple Shop.
it won't get to the login screen.
The boot disk is fine - I connected to it via target mode and 'repaired' it.
I've fsck'd it, reset PRAM and SMC.
I've removed all peripherals and tried safe mode.
it is booting cos I can login to my shares via the local network, but the machine itself won't boot from an external drive, a USB install disk, the original Leopard dvd etc.
All I'm getting is a mouse cursor on a grey screen.
The volume keys on the keyboard work.
Verbose mode doesn't help.
I've done short and long AHT tests and both report *no problem*
and this all started when it froze while playing music in iTunes.
