I’m thrilled to find this post as I’ve been trying to figure out how to do the same (share Trackpad).
I’ve setup the Magic Trackpad within Bluetooth settings on both of my Macs (iMac and MacBook Pro). Unfortunately, unless I turn off Bluetooth entirely on the Mac I’m moving from, the Mac I’m moving to will not connect to the trackpad via Bluetooth settings.
I can successfully disconnect the Trackpad via bluetooth settings on the Mac I’m moving from, but the Mac I’m moving to will not connect.
I realize this is outside of Toothfairy. But, if I can’t resolve the inherent bluetooth functions, I can’t take advantage of TF.
Any troubleshooting tips? thanks – jay
btw, both Macs are running Catalina
