After installing a new hard drive and updating my OS from 10.15 to 11.7, my Mac Mail search tool no longer works.
I tried rebuilding my inboxes. I have several accounts, and it would rebuild some of them but not my Gmail IMAP account. Then I tried deleting the Envelope Index files from my library. Search still doesn't work. I REALLY need it to work.
MacBook Pro, OS X 10.11
