MartinC, your development experiences and mine differ greatly. What sort of stuff do you write? There was a time (when I first got into Mac development) that the Mac looked like it would be the most lucerative market to develop speech recognition software for. The Mac had a better processor (for speech recognition, anyway). It had built in, high quality sound, when PC's had to screw around with installing things like SoundBlasters that were aimed more at gamers than at people who needed good audio quality. And it's market share was higher than it is today. But the OS just wouldn't support that kind of application complexity. That wasn't just my experience, it was also Apples, IBM's, and Dragon's. The Apple speech recognition development effort was incredible. Headed up by some of the hardest hitters in the business, cream-of-the-crop talent like Kai-Fu Lee and Steve Austin, skimmed from sites like CMU, MIT, BBN, IBM, AT&T. There should have been no limits to what that team could accomplish. But there was. First, they tried to move directly from UNIX to Mac. Then, they tried to use a "stepping stone", moving from NeXT to Mac. Then they gave up, and concluded it was impossible to do without Taligent, Pink, FutureOS, or any of the other names OS-X has had over the last 12 years. Remember, when you look at the size of target markets, "PC" usually means "PC with Windows 95/98/ME" and "Mac" means "Mac with MacOS 9". But the "PC" that made the Maya and 3DStudio folk see big $$$ was a much smaller market, the "PC with NT or Win2k" market. Far smaller than the installed Mac user base. Less graphics oriented. But that's what it took to run serious apps. Often, for smaller graphics houses, their first taste of NT came when it was time to install that brand new copy of Max. There were efforts to port those applications to MacOS 8 and 9. Costly, embarassing failures. Here's a thought for you. Poser itself was developed on the Mac, then ported for the PC. So, you'd expect Poser (and, the ProPack) to be more stable and better performing on the Mac than on the PC. So, why could it be possible that "Poser ProPack for Mac completely and utterly sucks"? What went wrong to cause this? If I were a betting man, I'd have money on programming difficulty as at least a partial cause.
