Uninstall McAfee Endpoint Security for Mac: Step-by-Step Clean Removal

Uninstalling McAfee Endpoint Security for Mac can feel like wrestling with digital barnacles—stubborn and sneaky. ⚡ I’ve helped enough friends through this process to know the official uninstaller often leaves behind preference files that trigger permission errors later.

The key is a systematic approach that covers every possible leftover, from the Applications folder to hidden system caches.

Before you begin, back up your data and disable McAfee’s real-time protection through its menu bar icon—this prevents it from blocking the uninstaller. Then, drag the app to the Trash, but don’t empty it yet. We’ll need to dig deeper.

The terminal commands that follow are your secret weapon for scrubbing out stubborn remnants, and I’ll walk you through each one step by step, including how to verify nothing’s left behind.

You’ll end up with a completely clean system, no lingering McAfee processes, and a smoother experience if you ever switch to another security solution.

The process takes about 15 minutes if you follow along carefully, and I’ll include troubleshooting tips for when things go sideways—because even with the best steps, macOS sometimes throws a curveball.

This method works for macOS Ventura, Sonoma, and earlier versions, though the terminal paths might vary slightly. We’ll also cover what to do if the uninstaller gets stuck or if you encounter permission errors—common pitfalls that trip up even experienced users. Let’s get started with the cleanest removal possible.

What you need

How to completely remove McAfee endpoint security from your Mac

Here's the foolproof method I use to purge McAfee completely—no leftover files, no hidden processes.

Open Activity Monitor from your Applications folder. In the search bar, type "McAfee" to filter processes. You'll likely see entries like McAfee Endpoint Security, McAfee Agent, and McAfee VirusScan. Select each one and click the Quit Process button (the stop sign icon).

If you encounter a process that won't quit, force quit it by selecting it and pressing Command + Option + Esc. This ensures no background services interfere with removal. I always do this first—leaving processes running can cause permission errors during uninstall.

Navigate to /Library/Application Support/McAfee/Endpoint Security/bin in Finder. Look for the file named uninstall.sh. Right-click it and select Open With → Terminal. In the Terminal window, type sudo ./uninstall.sh and press Enter. You'll need to enter your admin password when prompted.

The script will remove core components and prompt you to restart. Don't skip this step—it handles the heavy lifting of deleting system-level files. If you get a "command not found" error, double-check the file name and path. Some versions use uninstall.command instead.

Open Finder and navigate to these locations (one at a time): /Library/Application Support/McAfee, /Library/LaunchDaemons, and /Library/LaunchAgents. In each folder, look for any McAfee-related files or folders (they'll have "McAfee" in the name) and drag them to the Trash. Empty the Trash afterward.

For hidden files, open Terminal and run these commands one by one: sudo rm -rf /Library/Preferences/com.mcafee. sudo rm -rf /Library/Logs/McAfee sudo rm -rf /Library/Extensions/McAfee This removes preference files, logs, and kernel extensions that might persist. I always run these commands after the uninstall script—it catches anything the script missed.

Reboot your Mac. After restarting, open Activity Monitor again and search for "McAfee"—nothing should appear. Also check System Preferences → Security & Privacy → General to ensure no McAfee-related items appear under "Allow" or "Block."

For thoroughness, run a final check using Terminal: sudo mdutil -a -v This verifies your disk permissions are intact after removal. If you see any McAfee-related entries lingering in ~/Library or /Library, delete them manually. This step ensures your Mac is truly clean—no phantom processes or leftover files.

Tips & tricks for complete McAfee endpoint security removal

Real talk: Even following the steps perfectly can leave behind stubborn remnants if you don't know these key details. Here's what nobody tells you about getting your Mac truly clean.

System Integrity Protection (SIP) Consideration: If you're running macOS Sierra or later, you'll need to temporarily disable System Integrity Protection to delete those kernel extensions in Step 3. Reboot into Recovery Mode (hold Command+R at startup), open Terminal from Utilities, and run csrutil disable. This gives you the permissions to remove /Library/Extensions/McAfee files that would otherwise be protected. Just remember to re-enable SIP afterward with csrutil enable—I've seen people forget this and end up with security vulnerabilities.

Hidden Process Hunting: Some McAfee components register as system services that don't appear in Activity Monitor. After Step 1, open Terminal and run ps aux | grep -i mcafee to catch any lingering processes. You might see entries like mfevtss or mfefire that need manual termination with kill -9 [PID]. This extra step catches what the GUI might miss, especially on older macOS versions.

Permissions Troubleshooting: When running those Terminal commands in Step 3, you might encounter permission errors even with sudo. First verify your admin privileges by running sudo whoami—it should return your username. If you still get errors, try prefixing commands with sudo chmod -R 777 on the target directory first, then run the removal commands. This brute-force approach works when macOS gets particularly stubborn about file permissions.

Final Verification Shortcuts: The sudo mdutil -a -v command in Step 4 does more than check permissions—it also verifies your disk isn't reporting any corruption from the removal process. If you see errors here, run sudo diskutil repairPermissions / immediately. For a quicker check between reboots, use sudo kextstat | grep -i mcafee in Terminal to confirm no kernel extensions remain loaded.
