I have my trackpad connected to my Macbook Air and paired. I have the most up to date software for Macbook and trackpad installed. The trackpad moves the mouse around but it just won't do any double clicks, or 3/4 finger gestures. I have them all enabled in the settings menu. I've re-started, removed it from the bluetooth menu and re-paired like 5 times.

UPDATE: works on my wife's MBP just fine
