New Mail Notifications Not Working on Mac [Fixed]
In this guide, we will show you the steps to fix the issue of new Mail notifications not working on your Mac. The in-built mail app from the Cupertino giant allows you to create, access, and manage emails from all your accounts under one roof. Likewise, it checkmarks all the important formatting features as well, including the ability to add images, scan documents, create sketches, and attach files.
However, there are still a few rough edges that need to be polished. One of the most common complaints that we have seen with this Mail app is that the users don’t receive any notifications when an email arrives. Likewise, they don’t get any notification banners as well.
At the time of writing, the issue is only with incoming mail, as with outgoing emails, users get the alert sound as well as the banner. Furthermore, the message count on the Mail icon also does go up as well, so it’s just limited to the notifications. With that said, there does exist a nifty workaround that should help you rectify this issue. So without further ado, let’s check it out.
Fix New Mail Notifications Not Working on Mac

As of now, the only workaround that is spelling out success for the users involves deleting that notification sound and then letting it up from scratch from the Mail App. Here’s how it could be done:
- Close the Mail app. Then go to Launchpad > Others > Terminal.
- Now execute the below command in Terminal to reset the sound defaults delete -app Mail SoundName
- Make sure to replace the SoundName from the above command.
- Once done, launch the Mail app and you now set the desired sound.
