Hey guys, Does anyone know of a mouse for use with OSX that has at least 2 additional buttons (in addition to left, right, scroll wheel click) that are mappable to custom keystrokes? I was also looking for the ability to switch between custom profiles (e.g. one for web browsing, one for gaming). I have tried 2 mice so far: 1) Razer Orochi. Drivers appear to be very poorly written or incompatible with Lion. The software freaks out and crashes all the time and rarely works. I returned it. 2) Logitech Performance MX. A really good mouse, but it's a little big for my tastes and it seems to naturally track more northeast than I would like. The buttons are great and mappable, but the mouse doesn't support multiple profiles, so each time you want to have a different setup, you have to open the prefs and manually configure it which sucks. I'm going to return it. If anyone had any suggestions, I would be extremely appreciative. Thanks.
