Hey guys, Firstly I'm sure this has been covered before so please don't get angry at me, there's so many posts on here I didn't know where to start. So I have a MacBook Pro I purchased June 2006 running 10.4.11 Processor 2.16GHz Intel Core Duo Memory 2 GB 667 MHz DDR2 SDRAM It's been great and worked fine all this time but I mainly use my PC for uni related stuff. I need to upgrade to 10.6 to run the iOS SDK 4.3 as I want to start making iphone apps in my spare time. 1. Will this MacBook Pro be able to handle 10.6? 2. Would I be able to install the Snow Leopard disc straight from Tiger? 3. Would it be best to format my MacBook Pro and install Snow Leopard from scratch? (as I haven't formatted this computer since I have had it) 4. What will happen when Lion 10.7 comes out? Thanks guys, any help would be greatly appreciated. As I am a student buying a whole new computer right now is out of the question so I am hoping I will be able to make do with this one for a little while.
