Grey screen only when trying to update OSX...Help.

Hi Everyone,

I have a weird problem going on currently. My 13 inch macbook pro (2009) works PERFECT but I've tried 3 times to update to the OSX to 10.6.3 or 10.6.4 and everytime the update works but after it reboots I get the grey screen of death.

Any suggestions?

Second question:

When I have a time capable backup which I restore from when this happens so its not a big deal however whenever I restore I no longer have access to the old history. It's like the drive cannot go back in time. Is this normal?

 

hmmmm never thought of that. I'll give it a try. Thanks from one new englander to another
