I have been hoping to get my magic mouse working on 11.10. Full disclosure: I'm running AMD64, not on a Mac at the moment.
Here is a link to a thread I opened previously, with a good summary of what I have tried:
I didn't get any response on that thread. Hoping maybe the Apple forum will have something to say about this.
Essentially, I have heard that magic mouse multitouch gestures should be working on 11.10, but I haven't observed anything beyond basic mouse functionality. Does anybody have a magic mouse working with multitouch gestures?
Something that occurred to me recently. My machine doesn't have built-in bluetooth, so I use a USB dongle, and an older one at that. Perhaps this is the issue? Maybe I need to upgrade to a better (newer) dongle?
Any response would be greatly appreciated!
