Can't sign into Mac App Store

The App Store is one of the most important components of macOS, but many users reported that the sign-in isn’t working on their MacBook. This can be a problem, but there’s a way to fix it.

What can I do if the App Store is not working on my Mac?

1. Make sure that App Store is allowed to go through your firewall

Lock on MacBook keyboard

  1. Open System Preferences and click on Security & Privacy.
  2. Go to the Firewall tab and click on Firewall Options (you might have to click the padlock icon to unlock this button).
  3. Click the plus icon and select App Store.app.
  4. Save the changes.
  5. Restart the App Store and check if the problem is still there.

Unfortunately, your antivirus can also cause this inconvenience and the best solution, in this case, is to switch to a more reliable antivirus for your Mac.

We recommend Mac Internet Security from Intego for this purpose because it’s the best antivirus for Mac but also because it also detects PC malware.

Why is that important? Because you can also receive and then send PC files through your system infecting your contacts without knowing.

Mac Internet Security is light on your system and it doesn’t interfere with your apps and OS and when you connect your iPhone or iPad to your Mac, it will scan them too for safety.

As for online protection, this solution comes with an intelligent firewall that adjusts to your location condition for maximum protection.
