Hello,
I have an older Mac Pro (Dual-Core Intel Xeon 2.66 GHz) running 10.6.6
with a 250 Gb hard drive. I recently needed to switch out an internal drive from my Drobo. So I added this 1Tb drive to my Mac Pro, used the disk utility to erase it and then restore all the data from my 250 to it. So far so good. But when I tried to select the 1Tb as my startup disk in system preferences, I get this message:
"You can't change the startup disk to the selected disk. The bless tool was unable to set the current boot disk."
The guys at the genius bar had a few ideas, none of which worked. Any ideas anybody?
