Fix ‘An error occurred. (Error code: 9) (Extra code: 0)’ on Microsoft Edge Browser for Mac



Have you ever tried opening Microsoft Edge on your Mac computer only to be greeted by the vague but worrying error message – “An error occurred. (Error code: 9) (Extra code: 0)”? If yes, you’re definitely not alone. This error, which appears when you click the ‘About Microsoft Edge’ menu to update your browser, seems to be plaguing quite a few Microsoft Edge users recently, and the exact fix is still unclear.

Potential Causes – Microsoft Application Conflicts

Based on reports from other users, it seems recent macOS version and Microsoft application updates may be to blame for the “Error Code 9” issue starting to appear on MacBook Pro, MacBook Air, Mac Mini or Mac Studio computers.

Some possible explanations that have been floated include:

  • Recent macOS updates causing conflicts with Microsoft apps
  • Updates to Microsoft OneDrive and Office introducing bugs 
  • Changes by Apple to macOS security settings impacting Microsoft products

The fact that Microsoft Edge then disappears from the Microsoft AutoUpdate app lends credence to the idea of conflicts between Microsoft apps or between macOS and Microsoft tools.

Unfortunately, until Microsoft further isolates the exact triggers for this error, we can only speculate about what’s happening behind the scenes. 

Waiting for future software updates that hopefully address these conflicts may be our only choice at the moment.

In this post, we’ll explore some troubleshooting steps you can try to resolve error code 9 on Microsoft Edge chromium-based browser, on your own. We’ll also look at what might be causing this error in the first place. Let’s get started!

#1 Update your MacOS System Software

Before diving into application-specific issues, it’s always wise to ensure your core macOS software is up-to-date. Outdated operating systems can lead to all sorts of conflicts and problems with apps like Microsoft Edge. 

To check for macOS updates:

  • Open up System Preferences
  • Click on “Software Update”
  • If an update is available, install it and restart your Mac

macOS updates frequently include bug fixes and performance improvements. Installing the latest major updates gives Microsoft Edge the best chance of running smoothly. Don’t ignore those update reminders!

#2 Update Microsoft Edge Itself

With your system software refreshed, the next step is ensuring Microsoft Edge itself is updated. Even though this issue appears on the update window of your browser, it helps to check it once in a while to see if there’s any available update. Browsers in particular need constant updates to patch bugs, improve stability, and deliver new features.

You can check for Microsoft Edge updates by:

  • Opening the Microsoft Edge application
  • Clicking on the “…” menu button in the top right 
  • Going to Help > About Microsoft Edge
  • If an update is available, click on “Update”

Installing browser updates is a quick and easy way to nip many issues in the bud. Be sure to fully restart your system after the update completes. This will clear out any clutter from the old version.

#3 Reinstall The Application

If playing with updates doesn’t fix error code 9, more drastic measures may be needed. A good next troubleshooting step is fully reinstalling the Microsoft Edge application. 

This gives you a clean slate, removing any corrupted files or weird settings issues that may be plaguing your current install. 

To fully reinstall Microsoft Edge:

  • Delete the Microsoft Edge application from your Applications folder 
  • Empty the Trash to fully remove leftover files
  • Download the latest Microsoft Edge version from Microsoft’s website
  • Follow the setup prompts to install the fresh copy of Edge

Hopefully this forces the error to disappear for good! If not, don’t worry – we have a couple more things to try.

When All Else Fails, Contact Microsoft Support

Microsoft’s dedicated support teams may be able to uncover unique aspects of your system configuration that are leading to this error. They likely have more insight than the general public into what could be going wrong behind the scenes.
