Hi kwark, thanks for buying the game! I actually just got a used Mac Book Pro two weeks ago so I at least have the ability to create a Mac build again. I actually don't get asked about Mac much. Since launch, the game has only been downloaded for Mac a few times, which was a big part of the reason I stopped creating builds.
But I will create a 0.12 Mac build now that I have the ability :)
There were a LOT of changes between 0.10 and 0.12 that haven't been tested at all. It may be a few weeks before I have the time to get the Mac set up to build (this is non-trivial), build the newest version of the game, test it and publish it.
Thanks for buying the game and for your patience. I'll get you a build!
