That's good to know for when I install macOS Ventura sometime in the future.In MacOS Ventura, Apple finally fixed iMessage to allow for the deletion of multiple conversations at a time. Select the conversations you want to delete by holding the CMD key down while you click on the conversations. Then with a two-finger click (if you're using a track pad) select Delete.
well, it's not working with latest ventura update. I just tried, it's craptastic, not working, and if it's a link, you can only delete one by one. really crappy Mac UI as is typical. they've basically abandoned making it feature rich and logical based on what desktop/laptop users want and need. frickin arrogant dip wads. sick of apple. hate windoze more, but not by much.That's good to know for when I install macOS Ventura sometime in the future.
