I'm sorry, I don´t remember if I asked the question this way, or it's edited wrong. My question is if someone know where I could find MAC version of Playground SDK, ver 5, for download. I know that Playfirst cut the support for that SDK, but maybe someone have it on their computer and is willing to help. Playground up to version 5 is open source. Thanks for the answer Dan, but I think that your solution won't help, because question isn't about running some program on different OS. I need to compile my program with Playground SDK for MAC, and I could do that only with MAC version of SDK, so any emulator won't do in this case, because I'll end up again with Win version of my program, only compiled through emulator on MAC OS, that won't work standalone on MAC OS.
