Tip & Trick
To uninstall Microsoft apps from your Mac completely, you’ll need more than just dragging icons to the trash—leftover files can haunt your system. ⚡ I’ve seen this happen too many times: users think they’ve removed everything, only to find Microsoft apps secretly running in the background.
The real cleanup requires checking hidden folders, system preferences, and even digging into Terminal when needed.
Microsoft’s own uninstaller handles most apps like Office or Edge, but it often misses cached data and preference files. For a thorough job, you’ll want to manually hunt down those hidden folders—especially in your Library directory—and use built-in macOS tools like Activity Monitor to kill any lingering processes.
This method takes about 15 minutes but ensures your Mac is truly free of Microsoft’s footprint.
You’ll end up with a cleaner system that boots faster, uses less storage, and won’t nag you about Microsoft account logins. Plus, you’ll avoid the frustration of apps reappearing after updates. The key is patience—skipping steps usually means missing something, and I’ve learned that the hard way.
Works for any Microsoft app—Office, Teams, Edge, or even old versions you’ve forgotten about. Let’s walk through the exact steps to get it done right, so you’re not left with digital clutter. I’ll show you how to spot what’s left behind and what to do about it.

Step-by-Step instructions for removing Microsoft software from your Mac
Here’s the foolproof method I use to completely erase Microsoft apps and their leftover files.
🔧 Step 1: Quit All Microsoft Applications First
Before you begin, make sure every Microsoft app is fully closed. Open the Applications folder, then drag each Microsoft app (like Word, Excel, or Teams) to the Trash. Right-click the Trash icon and select Empty Trash to permanently delete them.
I always restart my Mac after this step. It ensures no background processes are running and clears temporary files. If you skip this, some apps might leave behind hidden processes that complicate the cleanup.
💻 Step 2: Use the Built-in Uninstaller for Office Apps
For Microsoft Office apps, some versions include a dedicated uninstaller. Open Finder, go to Applications, then right-click the Microsoft AutoUpdate app. Select Show Package Contents, then navigate to Contents/Resources/admin. Here, you’ll find the uninstaller file—run it to remove Office completely.
If you don’t see the uninstaller, don’t worry—this step isn’t mandatory. Just proceed to the next cleanup method. Real talk: some Microsoft apps are stubborn, so this step saves time if available.
🖱️ Step 3: Manually Delete Lingering Files and Folders
Open Finder and press Command + Shift + G to open the Go to Folder menu. Delete these folders one by one:
- /Library/Application Support/Microsoft
- /Library/Internet Plug-Ins/Flash Player.plugin (if Microsoft apps used it)
- ~/Library/Preferences (delete any files with Microsoft in the name)
Empty the Trash again after deleting these. This removes hidden app data, logs, and preferences that can cause conflicts. I always double-check by searching for Microsoft in the Spotlight search bar (Command + Space) to confirm nothing remains.
💡 Step 4: Reset System Preferences and Clear Cache
Open System Settings, go to General, then Login Items. Remove any Microsoft apps listed under Open at Login. Next, open Terminal (from Applications/Utilities) and run these commands one by one:
- defaults delete com.microsoft.office
- defaults delete com.microsoft.teams
- defaults delete com.microsoft.autoupdate2
This clears cached settings and resets permissions. You’ll love how smooth your Mac feels afterward—no more lingering app crashes or permission errors.
⏰ Step 5: Verify Complete Removal and Optimize Storage
Restart your Mac one last time. After reboot, open About This Mac and check Storage. Look for any leftover Microsoft files under System Files or Applications. If you see anything, delete it manually.
For extra cleanup, install Onyx (free) or CleanMyMac to scan for residual Microsoft files. This ensures your Mac runs faster without any hidden app remnants. You’ve got this—your Mac is now Microsoft-free!
Tips & tricks for complete Microsoft app removal on Mac
Some Microsoft apps leave behind more than meets the eye—here's how to avoid the most common cleanup pitfalls and ensure your Mac stays truly Microsoft-free.
Backup First: Before you begin, create a full system backup using Time Machine. I learned this the hard way after accidentally deleting important system files during a cleanup. You can restore your Mac to this backup point if anything goes wrong, and it gives you peace of mind knowing your data is safe.
Hidden Processes in Step 1: In Step 1, when you're closing Microsoft apps, don't just quit from the Dock or menu bar. Force quit stubborn apps by pressing Command + Option + Esc, selecting the app, and clicking "Force Quit." This ensures no background processes remain running. I've seen Teams or Outlook keep running invisible processes that complicate the cleanup.
Uninstaller Location in Step 2: If you can't find the uninstaller in Step 2, try searching your Applications folder for "Microsoft Office Uninstaller" or "OfficeUninstaller." Sometimes it's hidden in a subfolder. For stubborn Office installations, you can also use Apple's built-in App Cleaner & Uninstaller from the App Store—it often finds what the manual method misses.
Spotlight Search in Step 3: After deleting the folders in Step 3, perform a thorough Spotlight search (Command + Space) for "Microsoft" to catch any missed files. This catches hidden preference files or cached data that might still be lingering. I've found leftover files in unexpected places like the ~/Library/Containers folder that weren't in the standard locations.

Frequently asked questions
Got questions about uninstalling Microsoft apps from your Mac? You’re not alone—here are some common concerns and straightforward answers to help you navigate the process smoothly.
Will uninstalling Microsoft apps delete my files saved in OneDrive or Outlook?
Nope! Uninstalling Microsoft apps (like Word, Excel, or Outlook) won’t erase your files stored in OneDrive, Outlook, or other cloud services. Those files remain safe in the cloud or your local storage until you manually delete them. Always double-check your cloud storage afterward to clean up any unwanted backups.
How long does it take to fully uninstall Microsoft apps from a Mac?
The process usually takes 5–15 minutes, depending on your Mac’s speed and the number of apps you’re removing. The longest part is often scanning for leftover files (like preference panes or cache). If you’re thorough, it might take a bit longer, but it’s worth it for a clean system!
Can I uninstall Microsoft apps without affecting other programs on my Mac?
Uninstalling Microsoft apps is isolated to their own files and won’t impact other programs (like Safari, Chrome, or Adobe apps). However, some Microsoft tools (like Office) might leave behind preference panes in System Settings—always use a dedicated uninstaller or manually check ~/Library to avoid surprises.
What if I can’t find the Microsoft app in Applications to uninstall it?
If the app is missing from your Applications folder, it might be buried in /Library/Application Support or installed via a package installer (like .pkg). Use Spotlight (⌘ + Space) to search for the app name, or check Microsoft’s support page for app-specific removal steps. Pro tip: Third-party tools like AppCleaner can help track down stubborn files!
Should I reinstall Microsoft apps after uninstalling?
Only if you need them! If you’re switching to alternatives (like Google Docs or Apple’s Pages), you can skip reinstalling. But if you change your mind later, Microsoft offers free trials or subscriptions for Office apps. Just download them fresh from the Microsoft website to avoid leftover conflicts.
