Cannot update Edge on macOS

Question

Cannot update Edge on macOS

Marco Yip 35

User's image

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.

Hey everyone. I missed some important steps in my previous response. What worked for me is:

Back up all your data e.g. Bookmarks
Quit Edge completely
Run "sudo chown -R root:wheel /Applications/Microsoft\ Edge.app" in Terminal
Delete all files in ~/Library/Application Support/Microsoft (NOT the Microsoft Edge one!)
Delete the file ends with edge.plist in ~/Library/LaunchAgents (If any)
Delete the file ends with edge.plist in ~/Library/LaunchDaemons (If any)
Delete the file ends with edge.plist in /Library/LaunchAgents (If any)
Delete the file ends with edge.plist in /Library/LaunchDaemons (If any)
Clear cache by deleting all files in ~/Library/Caches
Reboot
WITHOUT running Edge, run "sudo /Applications/Microsoft\ Edge.app/Contents/Frameworks/Microsoft\ Edge\ Framework.framework/Helpers/EdgeUpdater.app/Contents/MacOS/EdgeUpdater --install --system --v=2" in Terminal
Edge checks update successfully

Please let me know if it works. I already reported the issue to Feedback portal.

Hello. Thank you both, Marco Yip and Dariusz Dobrowolski, for following up and sharing the results.

Marco Yip, your detailed steps and clarification were very helpful, and I’m glad to hear that the updated solution also worked for Dariusz Dobrowolski. Contributions like these can be valuable to other community members who encounter the same EdgeUpdater issue.

Thank you both for taking the time to help the community!

Hello everyone. After digging a little bit deeper, I realized that the EdgeUpdater in "/Library/Application Support/Microsoft/EdgeUpdater" is broken (I think). Using the command provided by AI fixed the problem:

rm -rf ~/Library/Application\ Support/Microsoft/EdgeUpdater
rm -f ~/Library/LaunchAgents/com.microsoft.EdgeUpdater.*
sudo rm -rf /Library/Application\ Support/Microsoft/EdgeUpdater
sudo rm -f /Library/LaunchDaemons/com.microsoft.EdgeUpdater.*
sudo /Applications/Microsoft\ Edge.app/Contents/Frameworks/Microsoft\ Edge\ Framework.framework/Helpers/EdgeUpdater.app/Contents/MacOS/EdgeUpdater --install --system --v=2

I don't know if it is a temporary workaround, but it did check the update successfully!

Hi, it didn't work for me—due to the lack of updates (I couldn't fully verify this), I switched to Dia Browser.

Hi Marco Yip,

Thanks for coming back and sharing what worked for you.

It’s helpful to know that rebuilding the EdgeUpdater components allowed Edge to check for updates successfully, especially since reinstalling Edge itself had not resolved the issue.

Since some of the commands you used remove system-level updater files, I’d recommend that other users avoid running them unless they understand exactly what is being removed. Hopefully your findings will also help narrow down the updater issue on macOS 27.

Thanks again for documenting the solution!

Hi Dariusz Dobrowolski

Thanks for the update.

Since you weren’t able to fully verify the result with a new update available, it’s difficult to tell whether your case is exactly the same as Marco Yip’s. I understand that you’ve chosen to use another browser for now.

If you’d still like Microsoft to investigate the Edge update behavior on macOS 27, you can report it through Edge > Help and feedback > Send feedback, including your Edge version, macOS build number, and the exact update error.

Thanks for sharing your experience here as well.

If Edge won’t update on macOS, I’d first restart the Mac and try the update again from Edge’s About page. If it still fails, checking that Edge has permission to update and that there’s enough free storage can help. As a last resort, reinstalling the latest Edge version usually preserves your profile and settings when they’re synced.

Thanks, Jassi Scott, for taking the time to share these troubleshooting suggestions. I appreciate your contribution to the discussion.

Answer 4

Since this started after the clean macOS reinstall, I would look at the EdgeUpdater installation rather than the Edge app permissions alone.

Microsoft has moved Edge on macOS to its own EdgeUpdater component, which is responsible for checking and applying Edge updates.

There have also been previous Mac reports with the exact “Error 9 (error code 0)” message where reinstalling Edge did not fix the updater.

I would check whether the EdgeUpdater components are actually present under /Library/Application Support/Microsoft/EdgeUpdater and whether the related LaunchDaemon/agent entries exist. If those are missing or damaged after the macOS reinstall, Edge can still run normally while automatic updating fails.

I also wouldn't assume macOS 27 is incompatible yet. If you can post the exact Edge version and whether edge://settings/help shows an updater version/error, that would help narrow down whether this is an EdgeUpdater installation issue or a macOS 27 compatibility problem.

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.

Thank you for your response. I am using official public version of macOS 27.0 (26A428). I am not using any third-party antivirus, VPN, adblocking or any profiles. I will report to the Microsoft Support. Thanks

Hello, I’m getting this error too; macOS version 27 official public

Hi Marco Yip,

Thank you for confirming that you are using the official public release of macOS 27.0 (26A428) and that no VPN, third-party security software, ad blocker, or management profile is involved. That information helps rule out several common causes of update failures.

Since reinstalling Edge and correcting the application ownership did not restore automatic updates, reporting the issue to Microsoft Support is the appropriate next step. Please include the Edge version, macOS build number, and the exact “9 (error code 0)” message when submitting the report.

Thank you again for the detailed update.

Hi Dariusz Dobrowolski,

Thank you for confirming that you are experiencing the same update error on the official public release of macOS 27.

Could you also share your exact Microsoft Edge version and macOS build number? You can find the Edge version at Settings and more > Help and feedback > About Microsoft Edge. This will help determine whether both reports involve the same Edge and macOS builds.

Please also submit the issue through Help and feedback > Send feedback, including the exact error message and diagnostic data if available. If Edge can only be updated using the full installer, you may also report the issue through Microsoft Support.
