Can a MacBook be hacked?

Yes, a MacBook can be hacked. Although macOS is one of the most secure operating systems, hackers still have their ways. Here are some factors that can make your Mac more vulnerable to hacking:

  • Outdated software: Running an outdated version of macOS or using outdated applications can leave your system exposed to known vulnerabilities
  • Weak or reused passwords: Using weak passwords or reusing passwords across multiple accounts increases the risk of unauthorized access to your Mac
  • Lack of antivirus software: Not having reliable antivirus software installed can leave your Mac susceptible to malware, viruses, and other malicious attacks
  • Unsecured network connections: Connecting to unsecured public Wi-Fi networks or using weak encryption can make it easier for hackers to intercept your data
  • Phishing attacks: Falling victim to phishing emails or websites can lead to the disclosure of sensitive information, giving hackers an entry point to your Mac
  • Unauthorized software downloads: Downloading applications or files from untrusted sources increases the likelihood of installing malware or spyware on your Mac.

On the other hand, there are several steps you can take to enhance the security of your Mac and make it more resistant to hacking:

  • Keep your software updated: Regularly install macOS updates and update all applications to ensure you have the latest security patches
  • Use strong, unique passwords: Create complex passwords, avoid reusing them across different accounts, and allow a password manager to store your passwords safely
  • Install reputable antivirus software: Choose a reliable antivirus program that provides real-time protection and regular scans to detect and remove malware
  • Enable the built-in firewall: Activate the firewall on your Mac to monitor and control incoming and outgoing network traffic, adding an extra layer of defense
  • Be cautious with downloads and email attachments: Download files and applications only from trusted sources and avoid clicking on suspicious links in emails from unknown senders
  • Secure your network connections: Use encrypted Wi-Fi networks and consider using a virtual private network (VPN) when connecting to public networks for added security
  • Enable two-factor authentication (2FA): Enable 2FA for your accounts whenever possible to add an extra layer of verification and prevent unauthorized access.

How to tell if your Mac has been hacked?

Detecting if your Mac has been hacked can be challenging, as hackers often strive to remain undetected. However, below, we’ve gathered advice on how to determine if your Mac has been compromised.

Unusual system behavior

One of the first signs that your Mac has been cracked is if you notice any unusual behavior or unexpected changes in its performance. Look out for the following indicators:

  • Frequent crashes or freezes: If your Mac suddenly starts crashing or freezing more often than usual, it could be a sign of a compromise
  • Slow performance: A significant decrease in your Mac's speed could indicate the presence of malware or unauthorized processes running in the background
  • Unresponsive applications: If applications take longer to launch or respond, it might be due to a security breach.

Strange network activity

Monitoring your network activity can help identify any suspicious connections or unauthorized access. Here's what you can do to check network traffic:

  1. Open Applications > Utilities > Activity Monitor
  2. Go to the Network tab, and observe the network traffic. Look for any unfamiliar or continuous connections.

What to do if your Mac has been hacked?

If you believe your MacBook has been hacked, it's wise to take immediate action to mitigate the damage and secure your system.


Follow these step-by-step instructions to respond effectively:

1. Disconnect from the Internet

Disconnect from the Internet by either unplugging the Ethernet cable or disabling Wi-Fi on your Mac. This action will restrict the hacker's ability to maintain access to your network.

2. Assess the damage

When assessing the situation, pay attention to any suspicious activities, unusual system behavior, or unauthorized access you may have noticed. Additionally, document any error messages, pop-ups, or unexpected changes to files as part of your evaluation process.

3. Change your passwords

Change the passwords for all your online accounts (email, banking, social media, etc.) from a different, secure device. Make them strong and unique, using a combination of upper and lowercase letters, numbers, and symbols.

4. Remove suspicious files

Trusted antivirus or anti-malware software will conduct a comprehensive scan of your system to identify any potential malware or suspicious files. If the software detects any malware or suspicious files, carefully follow the instructions provided by the software to remove or quarantine them.

5. Update and patch your system

Ensure your Mac's operating system and all installed applications are up to date. To update your Mac, continue with the next steps:

  1. Click the Apple logo in the top left and select System Preferences
  2. Select Software Update
  3. Check the box next to Automatically keep my Mac up to date

6. Enable firewall and FileVault

Activate the built-in firewall on your Mac to provide an additional layer of protection against unauthorized network connections and potential intrusions. Also, enable FileVault, a security feature that encrypts the contents of your hard drive. By doing so, you can safeguard your files, even if your Mac falls into the wrong hands.

7. Review and revoke unauthorized access

Review your user accounts thoroughly and promptly remove any unfamiliar or suspicious accounts you see. This way, you’ll prevent them from having control or undue influence over your system.

8. Implement two-factor authentication (2FA)

Enable 2FA for your accounts to introduce an additional layer of protection. Then refer to a trustworthy authenticator app or hardware token to generate secure and reliable verification codes for your 2FA.

9. Restore from a trusted Backup

If you have a recent backup of your Mac, restore your system to a point before the suspected hacking incident. This action will revert your system to a known, secure state. Then carefully evaluate the integrity of each file and verify its safety before transferring it back to your Mac.

10. Get an antivirus protection for macOS

Antivirus protection is indeed essential for macOS users to safeguard their systems from potential threats and hacking attempts. Here’s a checklist to help you choose reliable antivirus software:

  • Real-time protection: Ensure the antivirus software offers real-time scanning and protection, constantly monitoring your system for malware and suspicious activities
  • Malware detection and removal: Look for antivirus software that has a strong track record of detecting and removing various types of malware, including viruses, ransomware, Trojans, and spyware
  • Frequent updates: Regularly updated antivirus software is crucial to stay ahead of emerging threats. Check if the software provides frequent virus definition updates and security patches
  • Minimal system impact: Choose an antivirus solution that doesn't significantly slow down your Mac's performance or consume excessive system resources
  • Additional security features: Consider antivirus software that offers additional features such as web protection, email scanning, firewall, and safe browsing to enhance your overall security
  • User-friendly interface: Opt for an antivirus program with an intuitive and user-friendly interface, making it easy to navigate and configure settings
