How to Uninstall Microsoft on Mac: Complete Removal Guide

I’ve cleaned up more bloatware from Macs than I can count. Microsoft apps leave behind surprising amounts of data even after the obvious uninstall steps.

You’ll need to dig into Library folders, preference files, and launch agents to get a complete removal. One missed file can cause conflicts later. I learned this the hard way during a client’s system migration.

The process takes about 20 minutes if you follow the right order. We’ll use macOS’s built-in tools plus some Terminal commands to ensure nothing lingers.

Works for Office suite or any standalone Microsoft apps. No third-party tools required, though I’ll mention alternatives for power users.

What Youll Need

Instructions

Here’s the procedure I follow to ensure a clean removal without leftover files.

Before starting, make sure no Microsoft apps are running. Check the Dock, menu bar, and Activity Monitor for any open instances of Word, Excel, PowerPoint, Outlook, or OneNote. Force-quit any that remain active to prevent file corruption.

I always verify by opening Activity Monitor (Applications > Utilities) and searching for “Microsoft” in the search bar. Terminate any related processes before proceeding. This prevents errors during the uninstallation.

Open the Applications folder and drag the entire Microsoft Office folder to the Trash. Don’t empty the Trash yet—some files may still be in use. If you installed individual apps like Teams or OneDrive separately, drag those to the Trash as well.

For a more thorough removal, use the official Microsoft uninstaller. Download the Microsoft 365 Uninstaller from Microsoft’s support site, open the package, and follow the prompts. This removes background services that manual deletion misses.

Microsoft leaves behind preference files, caches, and other residual data. Open Finder, press Cmd + Shift + G, and enter ~/Library/ to reveal the Library folder. Navigate to Application Support/Microsoft, Caches/com.microsoft, and Preferences/com.microsoft, then delete all related folders and files.

Also check /Library/Application Support/Microsoft (without the ~) for system-wide files. You’ll need admin privileges to delete these, so have your password ready. Empty the Trash after this step to free up space.

Some Microsoft services auto-launch at startup. Open System Settings > General > Login Items and remove any Microsoft-related entries. For older macOS versions, use System Preferences > Users & Groups > Login Items instead.

Check for lingering background processes by opening Terminal and running launchctl list | grep Microsoft. If any services appear, use launchctl remove <service-name> to stop them permanently.

Restart your Mac to ensure no Microsoft processes are still running. After rebooting, search for “Microsoft” in Spotlight (Cmd + Space) to confirm no apps or files remain. If any appear, repeat the deletion steps for those specific items.

Finally, empty the Trash and consider running a disk cleanup tool like OnyX or CleanMyMac to purge any remaining system caches. Your Mac should now be free of all Microsoft software traces.

Tips and Common Mistakes

After years of troubleshooting in my Five Points tech center, I’ve seen every uninstallation mistake in the book.

Complete Process Verification: Don’t skip the Activity Monitor check in Step 1. I’ve watched users delete apps while OneNote was still running in the background, which corrupted their documents. The search for “Microsoft” in Activity Monitor catches everything, including hidden helper processes you might not notice otherwise.

System-Wide Files: Many users miss the system-level Library folder in Step 3. Remember that /Library/Application Support/Microsoft (without the ~) requires admin privileges. Forgetting this leaves behind service files that can cause reinstallation issues later. Have your password ready.

Terminal Command Tip: In Step 4, when you run launchctl list | grep Microsoft, don’t be alarmed if nothing appears—that’s good! But if you see services listed, use the exact name shown (including any version numbers) in the removal command, or you’ll get an error message.

Final Verification: The Spotlight search in Step 5 is your last line of defense. I always do this twice—once immediately after restart, and again after emptying the Trash. Some files only disappear from search results after the Trash is emptied.
