I can't really blame Lipsinc for not wanting to put forth the effort to develop for a niche market in a niche market, although in their case making a Mac version is probably trivial -- basically all their software does is read in a sound file, analyze it, and write a pose file (which is just text, the same format on Mac as PC). It's not like a game where there are video and speed issues involved. An experienced programmer could probably port it in a week. But there's the rub, Lipsinc probably hasn't hired any experienced Windows/Mac programmers. As mocap said, their stringing along Mac users is what rankles. I would suspect that the way to go in the future would be Python scripting, which could run on either platform, and be portable (with appropriate plugins or support files) to other animation packages as well, but that wasn't available when Mimic was under development (and is available only to Pro Pack users, but people who need Mimic probably also need Pro Pack anyway). No flames, timoteo1, just a simple observation that most people who have used both Windows and Mac systems (including myself) prefer Mac for its ease of use and consistency, although admittedly Windows has come a long way in recent incarnations. True, if I want to run the widest variety of software (90% of which is crud, in keeping with Sturgeon's Law), I'd use Windows -- but if I want to run the best software, and be most productive, I choose Macintosh. Technologies that are now PC standards were widely introduced to desktop computers on Macs: 3.5" floppies, SCSI, USB, FireWire. Apple had the guts to push the new technology so that the peripheral makers started making more products, and the PC makers followed by offering those features on their machines too. And it works both ways, Apple now supports inexpensive PC peripherals: I can buy a cheap IDE hard drive and VGA monitor for my Mac if I want. I'll admit that Macs aren't for everybody. But then, neither are BMWs. Some people are more comfortable driving Chevys, and if they're happy with that, fine.
