Hi, a couple of weeks ago, our magic trackpad (2) started to act up on our iMac (late 2015). It would start stuttering and eventually will lose the connection altogether. We used it with the lightning cable for a while and after some time it was working again. Until maybe a week ago, when the same things repeated. Now it will connect, but nothing happens. It will connect (and show up as 'connected' in the bluetooth preferences), but will loose the connection again, shortly after, even when connecting manually (from the menu). All that time, the bluetooth keyboard was fine, until today, when it suddenly stopped working. Now, it will show the same pattern of disconnecting shortly after connecting. For both devices, you can't have any inputs during the short time they are connected. Troubleshooting so far: - both batteries are full - turned Bluetooth and devices off and on a million times - removed devices from bluetooth list and paired again - plists in library/preferences and library/MyHosts deleted - PRAM reset The keyboard is working flawlessly on a macbook. The trackpads connects on the same macbook, but won't show up as bluetooth trackpad and hence no setting can be changed. That is with the macbook sitting right in front of the iMac, i.e. keyboard and trackpad are at the same location as before. I am aware that bluetooth might interfere with WiFi. However, we haven't changed anything and it was working fine for weeks. Some kind of interference also appears less likely in regard that the keyboard was still working fine despite the trackpad acting up - and the keyboard still working fine on the macbook. It might be something in the apartment above ours, but can't ask our neighbors to move their stuff... Any ideas are very much appreciated.
