Unfit as I am the grovel at the feet of El Presidente himself it is often the case that by the time Aspyr get their idle re-coding butts into gear and port a mac version then some common bugs are known and Aspyr fix them. The "Jump Bug" of the original game is an example. I've never seen an instance of it reported by a mac-user although of course I may be mistaken.
That's probably because by the time the Mac port came out, the Simantics code had already been patched, and so it's quite likely that the Mac version comes pre-patched. Your Mac version's Simcodes may be a more advanced, updated version of the PC version's, but it's highly unlikely that it differs from a comparable PC version's codes due to the obvious potential conflicts this would cause in downloadables.
