Microsoft Auto Update Turn Off Mac: Permanent Disable for macOS

by

That constant Microsoft Auto Update pop-up ruined my workflow one too many times. 💡 I finally found the permanent disable trick that actually sticks across reboots and app updates.

The fix lives in two spots: the Microsoft AutoUpdate app itself and a hidden system preference. You’ll need to quit the updater first, then adjust settings most users never see. Takes less than 2 minutes once you know where to look.

After this, your Mac stays quiet. No more surprise restarts mid-presentation, no more nagging update badges. The system behaves like it should—completely under your control.

Works on all modern macOS versions, from Ventura to Sonoma. Here’s the exact process I use on my work and vintage ThinkPad collection.

Tips & Tricks for Permanently Disabling Microsoft Auto Updates on macOS

These practical pointers will save you frustration and ensure the process sticks.

The Hidden Location: Confession: I wasted 20 minutes looking in the wrong place. Microsoft AutoUpdate often hides in a Microsoft subfolder inside Applications, not at the root level. Always check there first, especially on newer Macs.

Double-Check Preferences: In Step 2, after unchecking Automatically keep Microsoft apps up to date, also ensure How would you like to be notified? is set to Never. Some versions revert this setting, so I verify both boxes every time.

Terminal Command Caution: For Step 4, when running sudo chmod -R 000 /Library/Application Support/Microsoft/MAU2.0/, triple-check the path for typos. A misplaced space or slash can lock the wrong folder. I speak from experience—once locked my entire Applications folder by accident.

Persistent Processes: Even after following all steps, some Office versions install a secondary service. In Step 5, always open Activity Monitor and search for Microsoft Update Assistant—quit it if it’s running, or it’ll re-enable updates.
