10 Ways to Make Your MacBook Secure

While MacBooks are generally considered to be safe, it is always a good idea to beef up your security. 

The number of malware attacks on MacBooks is slowly increasing, so you do not want to be in a position where you lose all your data or have it breached. 

Here are 10 ways you can improve your MacBook’s security – 

#1. Use the in-built firewall 

A firewall prevents other systems from connecting to yours. It is pretty easy to turn it on on your Mac. 

Go to the menu bar and click on the Apple icon. Choose System Preferences and find the Security icon. Here, you want to click on the Firewall option. Switch it on, and you’re done. 

#2. Use Time Machine

Time Machine is an in-built feature on the macOS. It allows you to take snapshots of your system and regularly backs up all your data. 

Data backups are crucial, especially when it comes to data security. You can remotely wipe your laptop if it is misplaced or stolen. 

Before you back up your data, you should get rid of unnecessary files like temporary files, cache, duplicate files, and other junk. This also helps improve your performance on macOS.

You will need an external drive to back up all your data. If you leave it plugged in, automatic backups will be made regularly. 

#3. Disallow remote access

Being able to access your computer remotely is a good feature since you can collaborate with anyone in real time, but it can also be problematic from a security standpoint. 

It allows anyone to access your files remotely as well. So, it is best to turn it off. 

Go to System Preferences and find the Sharing tab in Network & Internet. Here, you can disallow ‘remote login’ and ‘remote management,’ and you’re done. 

#4. Encrypt your data

Data Encrypt

Another key feature that is built into your laptop is the data encryption feature called FileVault. This encrypts your hard drive so that if someone does manage to get their hands on your system, they won’t be able to access your data or make sense of it. 

You will find FileVault under Security and Privacy in System Preferences. Turn it on and follow the on-screen instructions to complete the setup.

#5. Use antivirus software and tools 

Just because you have a MacBook, you shouldn’t think you don’t need good antivirus software. You should invest in it to ensure your data remains safe. Using virtual private networks is a good piece of advice as well.

You also want to use in-built tools that your browser offers. And finally, make sure you turn on automatic updates. Updates to macOS are crucial for security features. Apple releases new security patches that your system needs. 

#6. Turn on password with screensaver

You should also turn on the password feature when you’re not using your laptop. This prevents anyone from getting into your laptop.

To turn this on, go to Security under System Preferences. You will find the screensaver settings here. Turn on the option to ask for a password. You can also customize the time delay so that it asks for a password after a couple of seconds or minutes. 

#7. Disallow logging in automatically

Disallow Login

If you have a laptop all to yourself and don’t work in a shared space, you can skip this one. But if not, you should think about removing the automatic login. 

Go to Login options under Users & Groups and turn the automatic login off. 

This prevents anyone from logging into your system without a password.

#8. Use a standard account

If you have your own laptop, you still might want to create a standard account. If malware makes its way to the admin account, then it will affect all your files. It is better to set up a standard account, and that way, all your files, and documents will be safe even if the admin account has malware or vice versa. 

#9. Get a password manager

One of the most common mistakes people make is to reuse the same password over and over again or to use a weak password. Instead of writing down passwords or trying to remember them, you should think about using a password manager like Keychain or Dashlane, which is a browser extension. 

#10. Disable ‘Spotlight suggestions’

Spotlight allows you to search your local device and the web. Due to a recent update, it is possible for someone to manipulate the search results and send you to an insecure website and share your data with an untrustworthy third party.

There you have it. Just practice data hygiene and keep your OS updated to make sure your laptop is secure.
