When you need a break from lap being cooked… `watch -n0.5 'pkill -f fileproviderd'`
I really could care less what it's up to. Whatever `fileproviderd` "needs" to do, it surely can be done without eating so damn much CPU time!
(not a request for help, just venting… and perhaps offering something useful to kin)
I bought an ARM-based Mac because of the efficiency. Longer battery life and less hot-plate action.
