I posted first thing this morning asking if the Mac OS X version was out, and by the end of the day I had downloaded it and started working with it. First impressions are good - the response time so far is faster than Poser 5 for many things, the default characters are better, some nice interface tweaks. I don't know what the memory error thing is but I'm assuming it's a Windows thing. The problem with Poser 5 on the Mac was slow performance but so far I'm happy I spent the $129. Now let's see if the Face Room has been improved or if it's just as clumsy as version 5.......
