Last summer we bought 3 Mac minis for some summer interns to use (biocurators) and I used the same apple account for each of them. We had a very confusing standup meeting the next day trying to figure out why seemingly random scientific text was continually replacing what had been in their clipboards. It turns out copying syncs across all devices, not just iOS <-> Mac.

Wait how the hell do you do that??

Ahhh I have handoff disabled (I cant stand getting phone calls on my laptop)

I believe you can turn this off from your phone: Settings > Phone > Calls on Other Devices

I got around it by having do not disturb on 24 hours.

You also can’t disable this without disabling handoff entirely.

Handover is brilliant. Once you get used to it, you really can't go back to the old ways.
