Universal Control frequently disconnects between M2 Mac Mini and M1 MacBook Pro
I have an M2 Mac Mini connected to an Apple 27" Studio Display and next to it (24") there is an M1 MacBook Pro 13" connected to an LG HDR 4K display. Both of the Macs are running MacOS Sonoma 14.3.1 at the time of this posting.
I am using an Apple wireless pro Magic Keyboard and a gen 2 Apple Magic wireless trackpad with Universal Control to operate both computers. This is especially helpful because it's difficult to reach the keyboard/mouse on the MacBook Pro while it is connected to my external monitor.
Ever since setting this up almost a year ago I have frequent (sometimes 20+ times a day) disconnects of Universal Control between the two computers. Occasionally (maybe 5% of the time) this is also accompanied by the Apple trackpad completely no longer responding. When this happens the mouse/cursor will jump back to the Mac Mini (primary) and no longer push through to the MacBook. After anywhere from 10-90 seconds it will automatically become reconnected and begin working normally again... for some period of time anyway.
Other times I've made it through a full day of working with only one or two disconnects.
Things I've tried to resolve the problem:
- Reboot and reset NVRAM on both computers.
- Running the keyboard and mouse with wired USB connections to the Mac instead of using them wirelessly.
- Eliminate possible sources of interference by disconnecting nearby devices, powering them off, etc.
- Set "reconnect automatically" under Settings->Displays->Advanced
- Disabling Firewall on both computers.
I'm really out of ideas at this point.
What more can be done to troubleshoot this problem?
