I recently did the firmware upgrade to EFI 2.3 on my MacBook Pro.
I subsequently had trouble getting my version of rEFIt working
properly, which if it did work, would allow me to boot into multiple
operating systems.
Specifically, when restarting my MBP, the screen would hang at the
grey Apple screen and would need to be restarted manually by pressing
and holding the power button.
I've decided to try to re install rEFIt, but before I attempt to do
so, I want to know if anyone else has had success in booting multiple
operating systems using rEFIt on this model of MBP and EFI firmware
2.3?
