I have Carrara 5 Pro. It runs well enough for my current needs. But I have noticed that when I attempt to render something, it "miss-renders" part of the objects when using it on an iMac core2duo. The same file works just fine on a G5.

What about Carrara 6. Does it have issues running under Leopard and Intel Macs?

If 6 fixes the issue, then it's settled, I will upgrade immediately.
