On Mac, open the iMessage app and then click on "Messages" on the top menu. Click "Preferences" and then choose Accounts. Uncheck "Enable this Account" under your Apple ID.

Method 2. Check iMessage Settings

If Method 1 doesn't work, you need to check your "Settings" to ensure you are signed in to both devices using the same Apple ID. With the iOS 15 released, some people find their iMessage settings have changed after the update.

Follow these steps to check your ID status:

On iPhone: Go to Settings > Messages > send & Receive. Under the "You can be reached by iMessage at" section, ensure your phone number and Apple ID are lists with a checkmark.

On Mac, open the Messages app, click "Messages" > "Preferences." Choose "Account" and under the "You can be reached for messages at" section, make sure the phone number and Apple ID match the settings on your iPhone.
