Customise Your Touch Bar

Reconfiguring the Touch Bar settings is another simple solution that yielded positive results for many users. Of course, use this solution only if your Mac has a Touch Bar. All you need to do is launch Mail and go to View. Select and add the Search function.

  2. Press and hold down the Shift key and then launch the Mail app again. Wait 5 seconds and exit Mail.
  3. Repeat the process, press the Shift Key, launch Apple Mail and close the app again.
  4. Restart your computer and launch the app normally. Check the results.

Manually Select Your Emails
