contactsdonationagent quit unexpectedly

yep, same here.

contactsdonationagent

from

/System/Library/PrivateFrameworks/ContactsDonation.framework/Versions/A/Support/ contactsdonationagent

and the biinary appears to have been written in Swift3

So far I think it's related to Contacts. Maybe a contact being added or deleted has caused something to break.

The plist refers to lots of related things

I am not the OP, but I am having the same problem. In my case it does persist after restarting and I have not noticed that it happens at a certain time of day, but for me it happens (I would guess) every couple hours. I'll try to get a better estimate of how long there is between intervals.

Same problem here, once or twice a day

Same here, I have noticed that always show this popup when wake-up my macbook after several minutes of inactivity...

Same problem here, also get the popup from AppleSpell
