delete multiple messages on mac
Hello. I want to regularly clean up the messages on my Mac, which is running 12.1. Previous articles and posts mentioned using the command or shift keys, selecting multiple messages and then deleting them. That doesn't work. There seems to be no way to select more than one message at a time, no matter what keys I'm holding down. The only other way to delete a message, one at a time, is to select it, right-click on "delete conversation," and then hit the delete button on the confirmation window. That is an utterly and ridiculously time-consuming method if I need to delete more than one message at a time. Any help out there?
