This is a really weird bug or behaviour:
1) copy a folder or file on Mac A
2) paste still on the same Mac A (basically just moving stuff via copy/paste instead of drag&drop)
3) Mac B that I haven't touched at all starts pasting the content (probably via Handoff/Shared Clipboard), causing massive CPU usage on both Macs (process "useractivityd"). When the local file operation is big (for example, moving video footage between local drives), the process just eats up Mac B's storage until it crashes with 0 kb free.

Anyone seen this? Both are on Big Sur 11.1.
