How to Delete Microsoft AutoUpdate from Mac

Delete Microsoft AutoUpdate from Mac

Want to delete Microsoft AutoUpdate from a Mac? Perhaps you uninstalled Microsoft Office or some other Microsoft applications from the Mac and thus have no further need for Microsoft applications to automatically update themselves. In any case, you can remove the Microsoft AutoUpdate application from Mac OS.

If Microsoft AutoUpdate is currently running you’ll need to quit out of the application first. You can also forcibly quit the Microsoft AutoUpdate app from Activity Monitor if needed.

How to Remove Microsoft AutoUpdate from MacOS

  1. From the Finder of MacOS, pull down the “Go” menu and choose “Go To Folder” (or hit Command+Shift+G) and enter the following path:
  2. /Library/Application Support/Microsoft/

  3. Locate the folder named something like “MAU” or “MAU2.0” and open that directory
  4. Locate and drag “Microsoft” to the Trash
  5. Delete Microsoft AutoUpdate application from the Mac

  6. Empty the Trash as usual *
  7. Close the MAU folder and continue using your Mac as usual

With Microsoft AutoUpdate deleted, Microsoft AutoUpdate will no longer be on the Mac or run to update software automatically.

If you still want to have and use Microsoft apps on the Mac, deleting the Microsoft AutoUpdate application may lead to some unintended consequences besides having outdated software from Microsoft, so it’s probably best to not remove it if you’re a heavy Microsoft software user, whether that’s Microsoft Office, Word, Outlook, PowerPoint, Excel, Edge, or anything else.

* You can also delete the file specifically from Trash if you want to leave other items in the Trash alone for now.

    Earlier today I deleted all of MS Office and what do you know! Just now MS autoupdate ran requiring me to OK some user license. Totally infuriating! Thanks for this tip, hope it’s good riddance this time.

  2. Keith C Smith says:

    Right-click/Control-click on the MAU2.0 folder and select Get Info. Click on the little Unlock button in the bottom right corner and enter your Admin username and password. In the Sharing & Permissions area, change Everyone to No Access. Click on the Lock button again and close the Info window.

    Check for Updates no longer appears in the Help menu of Office apps and the system can no longer run AutoUpdate.

    I don’t mind having Autoupdate running. What I mind is that:
    • I cannot choose to do installations manually, but I am forced to allow automatic download and installation
    • when I open a Word doc, I get an annoying banner telling me to run autoupdate. When I run it, it tells me there is nothing to update.

  4. Aidan says:

    After you locate the Microsoft Auto Updater you can double click on it and choose to turn off the automatic update, no need to delete the entire thing.

    • SysAdmin says:

      Wrong. It will always launch, and it always picks the most inconvenient time like when you’re screen sharing, or in the middle of a game.

  5. Mario says:

    I have just blocked it with Lulu…
    No need to trash it

  6. Tony Maceo says:

    Thank you for the easy to follow instructions. I deleted the file and the annoying update balloon no longer appears when I open my docs. I use Word sparingly but the autoupdate gave me the creeps when I could not stop it.

    I hate that these corporations insert program language into our machines and our software (we bought it, we own it) in an effort to get more money from their customers. Greed!

    Rather than throw the “MAU” or “MAU2.0” folder away and lose the ability to auto-update if you change your mind in the future, here’s how to hide MS Auto-Update:
    1) From the Finder of MacOS, pull down the “Go” menu and choose “Go To Folder” (or hit Command+Shift+G) and enter the following path: /Library/Application Support/Microsoft/
    2) Add a new folder in this folder and name it something MS will not recognize like “ms_auto update app”
    3) Drop the “MAU” or “MAU2.0” folder into the new folder and MS AutoUpdate app will be hidden from MS

    Thank you, so much! I read countless articles leading to no solution. Yours was the answer with no b.s. included. Just restarted the computer and it is totally gone!

  10. iAnna says:

    Thank you very much! What a relief!

  11. Mike W says:

    Thanks for this!

    It was killing me

  12. Jessica Lee says:

    I was so upset about this Microsoft auto-update option in my mac system. I could not delete from my mac os. Your article process gave me a solution.

  13. Isidore says:

    Another way of taming autoupdate is to use Little Snitch to block connections to Microsoft’s servers

  14. Djay says:

    it works. thankyou!

  15. Hardwoodhal says:

    Does this process work for eliminating updates to uninstalled Malwarebytes?

    • Paul says:

      No these instructions are only for removing Microsoft AutoUpdater.

      MalwareBytes is a totally different application from a different company, but that app should include a separate uninstaller if you want to remove it. You should also be able to uninstall Malwarebytes from that applications “Help” menu.

  16. Daniel Wells says:

    Thanks for the information – I’m getting the autoupdate window everytime I start up and the only microsoft software I’ve ever had on this machine was Silverlight…Silverlight in long gone, but the updater still remains.

  17. Bogdan says:

    You should also delete from ~/Library/PrivilegedHelperTools, from ~/Library/LaunchAgents and from ~/Library/LaunchDaemons

    • Paul says:

      Excellent additional information, thanks Bogdan!

    • Ayutube Sini says:

      I did a spotlight search on my MacBook Pro for Microsoft Autoupdate and saw the following folders:


      I can’t even locate them in the computer
      Are they viruses

  18. 1252 says:

    Thank you, but this information came for me 2 days late.
    I spent some two hours to find this autoupdater and I think it was placed in a different folder as displayed on the printscreen.
    I don’t know why Microsoft do not provide an uninstaller, are they thinking that once installed the user will not swap to iWork or some other free Office?
