What silly beta thing? If you're referring to the one in the first post of this thread it is the beta version of the ENGINE. Read the post to check how to run games with it (as it's only V2.71 many newer games won't work).
So basically, it is a beta thing that might run games but won't create games. Here is the error message I get:
Adventure Game Studio for Mac
Main game file not found. This may be from a different AGS version, or the file may have got corrupted.
Silly me thought in Beta mode, I'd be able to create something. :

And, as far as waiting for someone to step up to the plate? I've been waiting many years for a RPG game maker to be developed for mac that is freeware. Maybe with the unpopularity of PC right now, more people might step up start wanting to care about macs. However, I'd hate to hold my breathe. The problem with Ren'Py is that it really is a Visual Novel software whose tutorials are still in progress. I had this silly thought that something based on C type language, might be easier to learn because of the tutorials out there. And Stencyl, a JS based language has been in private beta testing mode for a very long time. Unfortunately, I have a friend on PC, and I'm on Mac. And, we thought it would be EASY to find a RPG game maker that works on BOTH systems! What a joke!

BTW, I did read one thread about how no one was getting the thing to work, and how Virtual machines, and some other software was needed (basically to run the PC version on a Mac, but they were supposedly talking about the Mac version.) And the person who mentioned taking this up again was NOT talking about MY Mac version. He was talking about the INtel chip which I do NOT have and CAN'T have in this computer because the MOBO is too old and doesn't support it! Sorry!
signing one stupid chick who needs to stop trying to find rpg game makers for a distcriminated against MAC that actually works on a PC too! It doesn't exist adn won't even exist until at least 2 full years have gone by. I've waited 12 years. I refuse to wait another 12 years!
