Cannot update Edge on macOS

Question

As shown above, Edge won't update automatically by itself throwing the error code "An error occurred while checking for updates: 9 (error code 0).".

The only way to update is to download a full Edge installer and replace the current install which is inconvenient. I have tried running the "sudo chown -R root:wheel /Applications/Microsoft\ Edge.app" command and reinstalling Edge but to no avail.

The issue happened when I clean reinstall macOS 27. So I am not sure if the issue is caused by the incompatibility between Edge and macOS 27.

Hi Marco Yip,

Thank you for explaining the issue clearly and listing the steps you have already tried.

Could you please let me know whether macOS 27 is a public release or a beta/developer build? Also, is the Mac using a VPN, third-party security software, DNS filtering, or a work/school management profile?

As a quick test, please temporarily disconnect any VPN or filtering software and check for updates again while connected to a different network. This can help determine whether the Edge updater is being prevented from reaching the update service.

Since you can update Edge successfully by running the full installer, you may continue using the latest installer from the official Microsoft Edge download page as a temporary workaround. Your browser profile and data should normally remain in place when installing a newer Edge version over the existing installation.

Please note that this is a user-to-user support forum. Moderators, contributors including external Microsoft employees cannot directly intervene in Microsoft product features or access back-end systems. My role is limited to providing technical guidance on reported issues, requests, or ideas.

I also recommend submitting feedback from Settings and more > Help and feedback > Send feedback. Please include the exact error, Edge version 154.0.4258.37 (arm64), the macOS 27 build number, and diagnostic data if available. This will give the Edge team the information needed to investigate a possible updater compatibility issue.

If the error continues even on another network with no VPN or security filtering enabled, please contact Microsoft Support and mention that reinstalling Edge and correcting the application ownership did not restore the updater. Thank you so much for your understanding.
