Hi Using Maya installed on a Mac Mini with

Intel Core 2 Duo
Processor Speed: 1.83 GHz
Number Of Processors: 1
Total Number Of Cores: 2
L2 Cache: 2 MB
Memory: 4 GB
Bus Speed: 667 MHz

This is a scene I am working on on a friends set up during my vacation. However, when I open the scene I had previously created on my work PC the hardware window scene tumbles extremely slow with barley half of the scene shown, as if I had less than 1 gig of RAM. I haven't even bothered to try any renders yet.

This is a scene I started on my own PC with OS: Windows XP, 2 Gig RAM. On that computer, the scene wasn't too big to view everything with no slowdown when tumbling.

Is this an incompatibility issue with a Mac? Is their a way to check to see if Maya is not using all the available RAM?

If there is anyone with any knowledge of what if anything I can do about this, I would welcome any help.
