How to Check and Remove Keyloggers on Your Mac
While the quickest way to identify and remove keyloggers from your Mac is using MacKeeper, there are other ways, too. Below, I have shared some other methods to identify and remove keyloggers from your Mac.
1. Use Activity Monitor to Check for Suspicious Processes
Activity Monitor is a built-in tool that allows you to check all your processes. You can use it to look for any methods with suspicious names or high CPU usage. Sometimes, keyloggers hide in plain sight, and doing a thorough search of the Activity Monitor reveals them.
To check for suspicious processes using Activity Monitor and remove keyloggers from your Mac, follow these steps:
- Open the Activity Monitor application by going to Applications > Utilities > Activity Monitor or searching for it using Spotlight (Command ⌘ + Spacebar).
- Once the Activity Monitor window is open, click the CPU tab to view the list of processes running on your Mac.
- Look for any processes that seem suspicious or unfamiliar in the CPU tab and if you find a suspicious process, select it, and click the i icon in the top menu to view more information about the process.
- In the process information window, you can see details such as the process name, process ID, CPU usage, memory usage, and more. Look for any information that seems unusual or suspicious. If the program is suspicious, click Quit to end it.
- Alternatively, you can force quit it by clicking the x button in the top menu.
2. Check Your Mac’s Privacy & Security Settings
Keyloggers on your Mac need certain permissions to work. To spot them, look at your Privacy & Security settings. Here, check for any odd or unapproved apps with access to things like Full Disk Access, Screen Recording, or Accessibility.
Revoking these permissions can disable the keylogger’s functionality. Here’s how to remove keyloggers from your Mac using the Privacy & Security feature:
- Access the Apple menu and choose System Settings.
- Click the Privacy & Security category.
- Under the Privacy section, examine different tabs, like Full Disk Access, Screen Recording, Accessibility, etc.
- If something seems suspicious, toggle it off to disable it.
3. Check Your Mac’s Login Items
Keyloggers often start when you turn on your Mac. To keep your Mac safe, check the Login Items in your user account and remove anything that looks suspicious. MacKeeper, a tool for cleaning and optimizing your Mac, can help manage these startup or login items.
Here’s how you can use MacKeeper to check and remove login items on your Mac:
- Download and install MacKeeper if you haven’t already.
- Launch MacKeeper and access the Login Items feature in the left sidebar.
- Click Start Scan.
- After the scan, the Login Items feature will display a list of programs set to launch automatically when you log in to your Mac.
- Carefully review this list for any suspicious or unfamiliar applications.
- If you identify any suspicious items in the list, select the checkbox next to the app’s name and click the Remove Selected Items button.
This will prevent the app from launching at startup, which can help delete malicious software and remove keyloggers from your Mac.
MacKeeper’s Login Items feature can manage startup items, but it may not be sufficient to fully remove keyloggers or other malware. It’s essential to use MacKeeper’s Antivirus feature to scan your system and ensure comprehensive protection.
Alternatively, you can change your Mac’s startup programs using System Settings:
- Launch the System Settings app from the Dock.
- Click General and select the Login Items tab.
- Select an item and click the Minus (-) icon to delete it.
- If a suspicious item is there in the list and you remove it, this should remove keyloggers from your Mac.
4. Remove PLIST Files
Keyloggers can hide as launch agents or daemons, which are processes that start when you turn on your Mac or log in. They use PLIST files to set themselves up. To stop keyloggers, you can delete these PLIST files. This stops them from starting automatically.
Here’s how to find and remove these PLIST files and get rid of keyloggers on your Mac:
- Open Finder on your Mac.
- Click Go in the menu bar and select Go to Folder.
- Explore the following locations:
- Find and remove any PLIST files with unusual file names.
5. Check the Library and Applications Folders for Suspicious Items
Although rare, if your Mac is heavily infected, you might find odd files in your Library and Applications folders. To keep your Mac safe, it’s good to check these folders for anything strange that might be keyloggers or other bad software.
Here’s how to look through your Library and Applications folders and get rid of any weird files:
- Open a Finder window.
- Click Go in the menu bar and select Go to Folder.
- Type the following path in the text field and hit Enter.
- Additionally, investigate all subdirectories in the folder, such as Application Support, for any questionable items. To display hidden files and folders, press Shift ⇧ + Command ⌘ + Period (.) in the Finder window.
- If you find any suspicious folders or files, select them, right-click, and tap Move to Bin.
Steps to Take After Removing Keyloggers
Keyloggers can steal your passwords, so right after getting rid of them, change all your passwords on your Mac. Once you’ve removed the keyloggers and updated your passwords, here are some more steps to make sure your Mac stays secure:
1. Enable Two-Factor Authentication
Two-factor authentication adds an extra layer of security to your accounts. It makes it harder for attackers to gain access even if they have your password.
To enable two-factor authentication on a Mac, follow these steps:
- Click on the Apple menu at the top left corner of the screen and select System Settings.
- Click Apple ID and select Password & Security.

- Once two-factor authentication is set up, you will be prompted to enter a verification code whenever you sign in to your Apple ID on a new device or make specific changes to your account.
2. Update Your macOS
Outdated macOS or any software is prone to malware and keyloggers. Updating your Mac and software ensures your Mac runs smoothly and any security vulnerabilities are patched.
Here is the easiest method to update your macOS:
- Click the Apple menu and select System Settings from the drop-down menu.
- Click General and select Software Update.
- If there are any available updates, you will see them listed in the Software Update window. Click Update Now to install all available updates.
