tthe, check the mac forum for more info. your render times sound about right. you know what you hafta do to speed it up: either cut way back on quality (which is what they normally do) or use something else (carrara, lightwave, maya, c4d). jim burton's benchmark test for P5 have indicated that, using a PC and a Mac with similar specs, the identical pz3 file (scene) will render slightly more than twice as fast on the PC. AFAIK it's still that way for P6, but I haven't seen any benchmarks for P6 yet, to compare OS X to XP Pro. I've only seen a test comparing an intel mac to an IBM/motorola mac, and the latter rendered about twice as fast as the intel mac.
