G4 Powerbook, 1.67 GHz, 2 GB ram, 10.4.8 ............. Poser6 was awful on my setup- I hated it ! It crashed frequently and generally behaved erratically. I had gone straight to 6 from 4ProPack which I had never had problems with at all and it still ran perfectly. I only got 6 so I wouldn't keep having to reboot into classic however . 7 works very well for me, glad I got it. I haven't yet installed sr1 though. From all I've read I will wait until sr2 or 3 I think. So I think Yes 7s good. All my previous props and figures work. I rarely use bought pose or light sets but the few I do have seem to work fine. Can't say anything about animation at all or how lipsync works. I bought V4, didn't like her at first, still preferred V2 &M2. Have tried her out for a while , do really find her easy to pose and will probably now ditch V3 from my runtime. But softwares unfortunately do seem to vary a lot system to system more and more. I also could barely run Vue5Inf however 6 works pretty well. Other mac users said 5 ran really well for them.
