I am interested in porting my (completed) Unity game to iOS, but I don’t have a Mac. I’m trying to pick one up as cheaply as possible (I will literally only use it for building/deploying to iOS, all my development will be on Windows).
Is there anything I need to look out for? I see a few older model laptops on eBay…but is Snow Leopard good enough for the latest version of Unity? Will a 2010 Core 2 Duo model support OS X upgrades to a more recent version? Performance is not an issue, but I want it to work with Unity 4.5 and the latest XCode/whatever else is needed for iOS development.
