OSX friendly ergo mouse

MX Revolution

 

Any mouse will work with any OS. No compatibility issues, other than an advanced function or two that might not be supported on Windows. It comes down to what features you want and what's comfortable to you.

 

Look through the Logitech website and find one that looks good, or go to Best Buy and try them out. I have yet to find a Logitech mouse that didn't work with Macs right out of the box.
