I never had any mac, but then I saw on ebay a mac pro for very cheap so I decided to buy it as it also came with screen keyboard and mouse

Anyway it turned out it isn't able to update beyond OSX 10.7

Anyway I compiled the program on 10.7 with clang (using dylib libraries compiled on 10.6.8 with gcc 4.2) and the executable runs

I assume that if the program runs on 10.7 it will still run on the latest?
