Works well for me, albeit very slowly but I think it's worth the 99$ upgrade. Bugs? A few but nothing like P5 PC. P5X doesn't refresh it's screen correctly when another app covers it. Python still has problems. I'm running a 1.4Ghz DP/1G RAM/OSX10.2.6 FF Render times - awful. If you look at Jim Burton's render test the Mac is about 45% slower then a comparable PC. As Jobe said, you should already have Mac PPP but make sure you get the SR's for it! I show V. 4.2.0.160 as the current version. HTH; Dan
