How to Detect Keylogger on Mac

Identifying the potential threat of keyloggers on your Mac is essential, even though macOS has a reputation for being an extremely secure operating system. In fact, threats can still slither in unexpectedly. So, having macOS doesn’t guarantee immunity from keyloggers and other ransomware. In this view, recognizing the signs of potential keyloggers is crucial for safeguarding your information. Our article aims to show you how to detect and remove suspected keylogger ransomware from your device.

Before we start:


If you worry your MacBook might be infected with harmful ransomware, you must act fast. It’s strongly advised to install reputable safety software like MacKeeper that can offer Antivirus protection as well as additional security with its Login Items feature. This tool scans your device to help you find keyloggers on your Mac and stop malicious processes.


Here’s how to use MacKeeper’s Login Items feature:

  1. Download the MacKeeper app.
  2. Once installed, open the app and click on the Login Items feature on the left.
  3. Click Start Scan.
  4. Once the scan is complete, you can look through the detected processes to help you identify anything that looks suspicious.
  5. Tick anything you want to delete and then click the Remove Selected button.

What is a keylogger

A keylogger is a type of malicious software that can hack into your computer and secretly record keystrokes, potentially compromising your sensitive information. This means that keyloggers can gain access to passwords, banking details, and personal messages without your knowing.


These programs can be detected by monitoring your Mac for signs of unusual system behavior or unexpected network activity. To check for keyloggers on your Mac, it's important to use detection software that can keep your Mac secured and your data private.

How common are keyloggers

Keyloggers are unfortunately a common threat due to the increase in PC hacking and ransomware attacks. Keylogger attacks have become a favored tool for cybercriminals looking to steal sensitive data without the victim knowing. The common occurrence and hidden nature of these cyber-attacks highlight the importance of making sure your computer is equipped with robust security programs to regularly find keyloggers on Mac and stop suspicious activity.

How do keyloggers work

Keyloggers function by secretly monitoring and recording keystrokes made by users on their devices. These malicious programs can capture keyboard information as well as record data from hardware devices. Once installed, keyloggers silently collect your data and transmit it to remote servers controlled by the attackers. This allows them to extract sensitive information without the user's knowledge.

Keylogger examples

Many notorious keylogger examples have surfaced over the years, each showing just how much of a threat they pose to our sensitive data. Notable examples include Zeus, a sophisticated banking Trojan known for its keylogging capabilities, and DarkComet, an online admin tool that has been frequently misused by cybercriminals for unethical spying. These examples emphasize the importance of regularly scanning for keylogger software on Mac to prevent your private information from ending up in the wrong hands.

Can Macs get keyloggers

Yes, a MacBook or iMac PC can get attacked by keyloggers, even though macOS systems are believed to be very secure; nobody is immune. These kinds of hard-to-spot threats are less common on Macs but can still occur. Therefore, we advise you to remain vigilant and regularly monitor your device with reliable MacBook keylogger detection software targeted to protect you against cyberattacks.


Before we move on to how to detect keyloggers on Mac, let’s first explore:

How can a MacBook become infected with a keylogger

A MacBook can get a virus and fall victim to a keylogger, like every computer or PC user.  What’s more, it can happen without realizing it. That’s why, it’s important to understand the common triggers of keyloggers to stop your Mac from becoming infected:

  • Try not to download malicious software from untrusted sources online.
  • Avoid phishing links in suspicious emails, pop-ups, or corrupted web pages.
  • Avoid visiting compromised or untrusted websites.
  • Never run your Mac with insufficient or outdated software, as it leaves you vulnerable to cyberattacks.

Signs of keylogger

The ability to spot and detect keyloggers on Mac can be hard as keyloggers are hidden in the background, but there are signs that you can look out for. Those signs include:

  • Sudden and unexplained changes in your Mac system affect how it operates.
  • Unusually slow performance as well as severe lagging can indicate keyloggers.
  • Suspicious network activity that you find unfamiliar, unusual, or don’t recognize.
  • Unexpected changes to your details could indicate that your data is compromised.

Tip from our experts: 


If you suspect keyloggers have infected your MacBook based on the above tell-signs, then we strongly advise you to run Apple’s built-in antivirus XProtect right away. That way, you can safely scan for keyloggers on Mac and quickly remove any potential threats.

How to find keyloggers on Mac

Finding keyloggers on a Mac requires a proactive approach that focuses on enhancing your system’s security defenses and removing anything from your device that you don’t recognize. It’s not an easy task to find keyloggers and other spyware threats, that’s why we’ll help you through it.

  1. Click on the Apple icon and select System Settings.
  2. Select the Privacy and Security category.
  3. Under the Privacy tab, scroll down and click on Full Disk Access.
  4. Look through the applications and if you notice anything unusual, untick the bar on the right-hand side to restrict access.
