So I have a Macbook Pro from 2008 I was given. Perfect condition. Intel Core 2 Duo 2.2GHZ, 3GB RAM, 8600GT and 120GB hard drive. I decided I was going to upgrade the hard drive to a 500GB 7200RPM drive. Bought that drive, looked up a guide to replace the hard drive in this version of the Pro and WHY IS IT SO DIFFICULT?! I had to take like 18 screws out of the system and literally try to separate the case in order to gain access. I literally felt like I was going to break something the entire time. To make things worse 1 screw got stripped, 1 SCREW! and I couldn't get it out and pretty sure that stopped everything from coming apart. I just gave up. Why the hard drive is in such a hard place to get at I have no idea! Thanks for listening to my venting.
