I just upgrade my air Mac now I can't delete my messages it has the delete conversation feature but when I click on it nothing happens

Hi rebeca158,

We understand that you're having trouble deleting conversations from your Messages app. Have you tried restarting the app and your Mac to see if the issue persists? This can sometimes help with minor software issues. Does it persist with every conversation that you try to delete? Is this the only function that's not working properly in the app? This will help us understand your issue better. We look forward to hearing back from you.

Take care.
