Hey all, I have had Tiger on my MBP since i bought it in August 2007. The MBP has a 2.4 Ghz IC2Duo and 2GB of DDR2 SDRAM. I need to update to Snow Leopard for numerous reasons, the foremost being school work and the fact that I just bought an iPhone 4 and can't sync anything on my computer with it. The question I have is whether or not I can use the 29.99 Snow Leopard to upgrade my OS. I have read that you can do it with no issues, or that you can do it and it will tell you that you need OS 10.5 (Leopard). Being a student, I can't really afford to shell out 129.99 for the box set, especially when Windows users can upgrade from XP to 7 without any issues other than hardware. If I can upgrade straight to Snow Leopard, how do I go about doing it? I've never installed anything on my MBP other than Firefox and VLC, so you can probably see where installing a whole new OS would be daunting. Should I backup all of my data on my hard drive to an external? These questions, etc... If anybody can get back to me on this, I would be eternally grateful.
