I installed the OS update 10.6.7 on my MacBook Pro two days ago. There seemed to be some problems with this version on my machine as I would get the spinning wheel, and the system would freeze. Tiring of having to power down and restart constantly, I erased the hard disk and used Time Machine to restore the to the pre-update state with 10.6.6 as the OS. The restoration was reported to have occurred normally. However, now the machine won't boot up.

The laptop is about 4.5 years old and well out of warranty. I am repeating the restoration from the Time Machine backup right now. If this doesn't work, are there suggestions for what to try next?

Thanks for the assistance.


MacBook Pro, Mac OS X (10.6.6)
