UPDATE: We’ve got some great news for Mac folks! We’re going to have Mac versions of all* of the Anniversary Collection! We’ve teamed up with some really amazing people at Codeweavers who specialize in this sort of thing (and are also Myst fans), and they’ve been able to make macOS versions of all the games* from the Windows versions — no additional emulation software is required.
After the Kickstarter ends, each Backer will fill out a survey where (among other things) they can choose either Windows or macOS. (No need to do anything until you receive the survey - and no ETA on when the survey is coming.)
* There are caveats, so keep reading…
First Caveat: Myst: Masterpiece Edition is giving us trouble. We’re working on it, but we’re not sure about it. Soooo… we’ll be converting the original Myst to fill that hole.
Second Caveat: Flux. Any of this could change - for the better or for the worse. Because there is testing going on right now, we want you to be aware that there is a little room for some wiggle, but we’re obviously feeling very secure about the Mac versions.
Apple has always been a part of Cyan’s history. And Apple/Mac users are a very important part of the audience for our games. As we’ve said before, Rand only uses a Mac at home and work. However, these facts do not directly correlate to resources for Mac updates. Those updates require substantial time and effort to update or rebuild the games from the ground up.
Changes and updates to Apple's hardware (example: migration from PowerPC to Intel), software (example: discontinuation of HyperCard), and the MacOS platform (example: switch to OS X) make the Mac a wonderful modern ecosystem, but can create sometimes overwhelming challenges to small developers trying to update older titles.
