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.

I am. having issues with this and I have tired these commands and I still cant get Edge to Update. Have you had this problem come back or recently? Thanks

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.

What worked for me (MacOS 27.0.1) was to completely uninstall Edge, and install an older Business version of Edge downloaded from here. Once installed, it autoupdated properly and the issue was resolved.

I used MicrosoftEdge-150.0.4078.105.pkg, which then autoupdated to the latest version.

Note that the Business version of Edge uses an installer package rather than a dmg.

I've been trying to fix this issue for so long, with the assistance of Copilot, after installing MacOS 27. You're steps above worked and now Edge is updating in Settings... About Microsoft Edge. Thank you very much for sharing this with us.

what am I missing? I was not able to get this to work.

the first step, "sudo chown -R root:wheel /Applications/Microsoft\ Edge.app" gives an error message, "Operation not permitted"

I did all the other steps but nothing has worked so far.

so, I installed the business one mentioned that comes in a .pkg file and that did work!

wasted quite a bit of time on this one – thanks all!
