Well, I finally convinced my dad to buy me a mac book since everything on here works better with it! I was looking at cheaper versions cause I think 700 bucks + is just to much for something I'm going to use very rarely because I've been a windows user since day one. The only reason I need one is just to test my apps and then post them on market and well I make a bunch of apps so I don't wanna pay $20 everytime to rent the mac in cloud. So are there any system requirements? Like on the operating system ?
