I am new to the forum and hope you all can help. I build and repair PCs for a living so please don't hold that against me. My wife loves Apple and I just got her a 2009 MacBook Pro 13.3 in. It came loaded with OSX 10.6.3 and has the DVD Snow Leopard disk 10.6.3. - 2009 A1278 - 4GB DDR3 RAM - 2.4Ghz Intel Core 2 Duo - Nvidia 320M 256MB graphics I got it home powered it up and it was great. Wife got an update notice for 10.6.8 so she said yes. After the install it rebooted now it locks up at boot screen, every time. I had to pull the hard drive, format, re-install and as long as I keep 10.6.3 I am good. That is not going to work when it keeps telling me I have this update.
