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?
