Q: Magic Trackpad 2 and El Capitan - not finding trackpad

I am having the exact same problem and I am using the 10.11 public beta on a 2012 MacMini with Bluetooth 4.0.

I had the same problem I fixed it by downreving the software the the release version syncing the magic trackpad 2 and then upgrading the software and everything now works great. Some thing in the beta is either not recognizing the trackpad or recognizing it as a mighty mouse I had both issues. Works on multiple machines tested this fix on my 5k iMac and Macbook 13in retina pro (fully loaded) and both work perfectly now....

Glad to see you found a solution.

What software did you download to cure the problem? Thanks!

I just downgraded from El Capitan 10.11.1 Beta to the standard app store 10.11 El capitan it is a free download. Then after I downgraded and installed the trackpad. I was able to upgrade again to the beta with no issues.

I have exactly the same problem with the final version 10.11.1. The trackpad is connected and working well, unfortunately it is not configurable because under "Settings" -> "Trackpad" -> "Set Up Bluetooth Trackpad" the device is not found. Any solution?

Try leaving the Trackpad connected via Lightning to Mac USB port. Once I did this it paired and I could take the cable off, but if you continue to have problems you might need to keep the cable plugged in until Apple updates drivers.

you have NO idea how frustrated i was trying to figure this out!

thank you!!!
