Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Microsoft AutoUpdate is typically installed at the system Library level, not the user Library. If the Microsoft folder is missing where it was checked, the likely issue is that the user Library was opened instead of the system Library.
Try this path in Finder:
- Open Finder.
- Press Command + Shift + G.
- Go to:
/Library/Application Support/Microsoft/ - Look for the MAU2.0 folder, which contains Microsoft AutoUpdate.app.
If the goal is only to stop the pop-ups, the safer option is:
- Open any Office app such as Word.
- Select Help > Check for Updates.
- Clear Automatically keep Microsoft Apps up to date.
Removing Microsoft AutoUpdate can prevent Office apps from receiving security updates and feature improvements. Administrator credentials might be required if the MAU2.0 folder is removed.
If Microsoft AutoUpdate is failing or behaving incorrectly, installing the latest version of AutoUpdate is the documented fix for issues caused by missing helper files or incorrect permissions.
