Well, if you're using an Apple certified mac (Eg it came from them, stock) it's going to work with no problems.
If you're using Hackintosh, I wouldn't expect it to work brilliantly.
I would say OSX would be a bit faster, but that's just me. I find they have less services and ram-hogging applications running, just to run the OS.
Don't forget linux either! Most render nodes are running linux as it's very lightweight.
So in short, I would say Mac if you're running real Apple hardware, or Linux if you're running a PCish box.
Imagination is more important than knowledge.
