My html email signature disappeared in Mac Mail upon updating to Monterey!?!?!?
A number of years ago I had put my html email signature into Mac mail by following some steps and putting it into the mail folder (etc etc) in the library folder. Upon updating my iMac and MacBook Pro, my signature suddenly disappeared and the mail folder in the library folder has also disappeared. What should I do?!?
iMac 27″, macOS 12.3
