Restart Your Mac and Update in Safe Mode

Booting your Mac into Safe Mode helps determine if third-party software, antivirus programs, or background processes are interfering with the Microsoft AutoUpdate utility.

Safe Mode performs basic checks and prevents certain software from automatically loading or opening. This creates a clean environment to run updates without external interruptions.

1
Shut down the Mac

Click the Apple menu in the top-left corner of your screen and select 'Shut Down'. Wait for your Mac to turn off completely.

2
Boot into Safe Mode

Turn on your Mac and immediately press and hold the 'Shift' key. Release the key when the login window appears. You should see 'Safe Boot' in the upper-right corner.

3
Run Microsoft AutoUpdate

Open Microsoft Word or Excel, click on 'Help' in the top menu bar, and select 'Check for Updates'. Try running the update process again to see if it bypasses the 'Processing' stage.

Restart Your Mac and Update in Safe Mode
Apple Silicon Macs: If you are using a Mac with Apple Silicon (M1/M2/M3), the Safe Mode process is slightly different: shut down, press and hold the power button until 'Loading startup options' appears, select your volume, press and hold Shift, and click 'Continue in Safe Mode'.

Frequently Asked Questions

Why does Microsoft AutoUpdate keep getting stuck on 'Processing'?

This usually happens due to corrupted AutoUpdate preference files, conflicts with third-party background software (like antivirus tools), or insufficient disk permissions preventing the installer from applying the update package.

Can I update Microsoft Word and Excel without using AutoUpdate?

Yes, you can manually download the standalone update packages for Word, Excel, and other Office apps directly from the official Microsoft Office for Mac release history webpage and install them manually.

Will deleting Microsoft AutoUpdate delete my Word or Excel files?

No. Deleting the Microsoft AutoUpdate tool and its related library files only removes the updater program. Your personal documents, spreadsheets, and the actual Office applications remain entirely unaffected.

Where are the Microsoft AutoUpdate files located on my Mac?

The core files for Microsoft AutoUpdate are typically located in the system Library folder at '/Library/Application Support/Microsoft/MAU2.0' and its launch agent files are in '/Library/LaunchAgents/'.
