What Is Microsoft AutoUpdate?
Microsoft AutoUpdate is Microsoft's updater for macOS. It checks for and installs updates for Microsoft apps such as Office, and may also handle related Microsoft components you have installed.
On a Mac, it usually runs in the background through Microsoft's update framework rather than as an app you open every day. Its job is simple: keep Microsoft software current without making you manually check for updates.
Is It Safe?
Yes, if it is the legitimate Microsoft component. Microsoft AutoUpdate is a normal part of Microsoft Office and other Microsoft software on macOS.
If you want to verify it, check that it is tied to Microsoft Corporation and located in a Microsoft-related app or Library path. On macOS, you can also use Finder's Get Info or Activity Monitor to inspect the process, then check the code signature in System Settings or with Gatekeeper tools if needed. If the name appears with an unusual location or no Microsoft signature, treat that as suspicious and investigate further.
Should I Disable It at Startup?
Usually no. This is one of the startup items that is generally worth keeping because it delivers security fixes, bug fixes and compatibility updates for Microsoft apps.
You can disable it if you prefer to update Office manually, but that means you must remember to check for updates yourself. Disabling it should not stop Office apps from opening, but it can leave them outdated.
Verdict: keep it enabled unless you have a specific reason to manage Microsoft app updates manually.
Why Is It Using High CPU or Memory?
Short bursts of CPU, disk or network use are normal when it is checking for updates, downloading them or preparing an install. You may notice this after login, after waking your Mac, or after a Microsoft app update becomes available.
If usage stays high for a long time, common causes include a stuck update check, a failed download, or a damaged update cache. Quitting Microsoft apps, reopening AutoUpdate, and checking for updates again can help. Restarting the Mac may also clear a hung updater process.
If the process keeps consuming resources even when no update is happening, inspect the exact process in Activity Monitor and confirm it belongs to Microsoft.
How to Disable or Remove It
The safest option is to turn off automatic checks inside Microsoft's updater rather than deleting files by hand. In many Office installs, you can open a Microsoft app, then open the Microsoft AutoUpdate tool from that app's Help menu or from Microsoft's application support files, and change update preferences there.
You can also review background items in macOS login and background permissions if Microsoft components are allowed to run automatically. Exact menu names can vary by macOS version.
If you want to remove Microsoft AutoUpdate completely, uninstall the related Microsoft apps using Microsoft's own uninstall steps or your normal app removal method. Do not manually remove random Library files unless you are sure they belong to Microsoft.
Where Kudu Helps
Kudu can help you see whether a Microsoft background item is set to launch automatically on macOS and disable it from Startup Manager if it appears as a Launch Agent. If a Microsoft updater process is using too much CPU or memory, Kudu's Performance Monitor can show the exact process and resource usage so you can confirm what is running before you quit anything.
Kudu will not remove Office updates for you, but it can help you review startup entries and spot whether a background item looks normal or needs investigation.
Frequently asked questions
- Can I use Office on my Mac if I disable Microsoft AutoUpdate?
- Usually yes. Disabling AutoUpdate normally stops background update checks, not the Office apps themselves.
- Is Microsoft AutoUpdate malware?
- The real one is not malware. If the process is in an unusual location or is not signed by Microsoft, investigate it before trusting it.
- Why does Microsoft AutoUpdate start when I log in?
- It often runs in the background so it can check for updates automatically. That is normal behavior for Microsoft's macOS updater.
