Stop using iMessage

If you don’t want to see messages on your Mac, you can sign out of iMessage.

1. In the Messages app  on your Mac, choose Messages > Settings, click iMessage, then click Settings.

2. Click Sign Out, then confirm that you want to sign out. When you sign out of iMessage, you no longer receive messages on your Mac.

Note: If you want to stop receiving messages sent to your phone number, deselect the phone number below “You can be reached for messages at.” See the Apple Support article Add or remove your phone number in Messages or FaceTime.

All the best.
