For this, we need to ask JMteam09 (Jordi vd Molen) , but to be honest the dev team is kinda busy with 1.5 update, so he probably won't have a lot of time...
No, the PC 1.35 is specifically a Windows port. Won't work on a Mac unless you do some stuff and make it dual boot Windows. I won't go into that here, not the place, and I don't have the XP to comment on such topic.
