I was not being flip about it. I really can't see how you can be the least bit productive working Maya without a 3 button mouse. I have a MBPro as well as a MacPro. That particular mouse I linked to at Newegg is small, the wireless receiver stores in the mouse and acts as a switch to turn it off. Battery lasts for months. Mac's natively want to only be one button. You can get a rt mouse button by putting two fingers on the pad, holding down click, releasing the two fingers and then draging on the pad. I know of no way of getting a middle mouse button just using keyboard/trackpad incantations. Just getting a rt mouse button is near rediculous. It is your pain but unless your only Maya time is sitting somewhere with your laptop in your lap, I'd get the mouse and save Maya time when you have a table.
