that Contacts one hits hard, no idea how many hours I wasted trying to figure out what the hell it’s doing.

Just today was looking at Activity Monitor Disk tab, for an unrelated reason - sorted by Bytes Read, lo and behold ‘contactsd’ - the Contacts daemon, is in 2nd spot at ~400 _gigabytes_ read, right after mediaanalysisd. I don’t even remember last time I opened the Contacts app on my Mac. It felt like it’s gonna be another time sink with no solution, so I didn’t even bother to investigate more.
