Hi everyone, I am currently bidding on a 2012 retina 15" macbook pro, as I need a replacement to my current 2010 13" model, and wondered about future updates. I could of went for a current model 13" macbook pro, but I really want the 15 with a i7 as I am running logic and the extra screen space is handy, not to mention the quad core i7 vs dual core i5. I just wondered really if future mac OS updates are likely to be compatible with a 2012/2013 model? I realise my current model supports the latest mac OS, and just wanted to make sure this will be the same for models that use I7 processors. Benchmarks are better for the 15" old macbook pro vs new 13", but will I notice this in the real world too? Thanks for your help, Conan.
