9 Ideas to Protect a Mac From Cybersecurity Threats

Update on

Despite being quite reliable, even Macbooks can be prone to cybersecurity threats. Moreover, there are instances when you are not the only person using the computer, and guaranteeing that another user will not mess up is more or less impossible.

Thankfully, there are ways to fortify the security of a Macbook and give yourself peace of mind. If you read this article, you will become more familiar with what it takes to create a strategy to fight against potential malware and viruses. The ideas below should be a good reference.


Idea #1 – Be Creative With Passwords

Passwords should not be just a random word or a number combination. You need to be more creative. Generate a password with a tool online. If you cannot memorize it immediately, write the password down on a piece of paper.

It is also recommended to change passwords regularly. You may take advantage of accountsd on Mac – a database that stores credentials for Mac applications.

And finally, do not get in the habit of using the same password for multiple accounts. If someone finds out your password from a random website, they will have access to more important profiles, such as social media or emails.


Idea #2 – Enable the Firewall

The Firewall is disabled by default, but you can change that in the Firewall tab in security settings on the computer.

Think of the Firewall as another layer of security. The tool blocks incoming connections unless you make some exceptions. It also prevents probing requests thanks to the stealth mode.


Idea #3 – Prevent or Limit Physical Access to the Mac

Physical access is not a problem if you live alone and keep the Mac at home. However, if someone else uses the computer, or there is a chance that it might get stolen, you have to make some adjustments.

For starters, disable the auto-login feature. This way, people will need your permission to access the computer’s contents. Creating a non-admin account and disabling certain features would also decrease the odds of potential threats, particularly when it is someone who lacks experience using a Mac.


Idea #4 – Install a Reliable Antivirus Software

Do not rely on the default antivirus that you find on Macbooks. Some users reported that XProtect causes some issues.

Since a solid Macbook cybersecurity strategy revolves around antivirus software, the first thing to do would be to replace XProtect.

There are plenty of good choices. Ask your tech-savvy friends for recommendations. If you do not know anyone like that, spend time researching online. And keep in mind that even if you do not have the money to spend on an anti-malware tool, you can still find a decent choice for free.

Make sure that antivirus software is running and scanning the system all the time. Once it finds a potentially corrupted file, do not hesitate and remove it from the disk.


Idea #5 – Get an Ad Blocker for Internet Browser

An ad blocker helps because you may click on a pop-up and get redirected to a landing page that is crawling with malware.

Ad Blocker

In addition to disabling this threat, an ad blocker will also improve your overall browsing experience as you will not have to encounter advertisements. And once again, it may be that someone else who uses the Macbook may click on an ad and cause you problems later. Eliminating this possibility in advance thanks to an ad blocker extension seems worth it.


Idea #6 – Keep the OS up to Date

The lack of operating system updates means that you are missing out on more than just the latest features and performance upgrades.

Security is another big aspect of each update. If you fail to install the most recent version, you may expose the Macbook to the most recent malware. And there are instances when even reliable antivirus software cannot help if the system is not up to date.

Despite some updates taking a while to download and install, you should still prioritize them. At the end of the day, it is better to be safe than sorry.


Idea #7 – Browse the Web Using a VPN

Virtual private networks enable anonymity online as your browsing history, and other data is encrypted. You can also access geo-restricted websites.

A VPN comes in handy, particularly when you have to use public internet. Wi-Fi at hotels, libraries, and cafes are an excellent location for hackers who want to set up traps and attack unsuspecting people.


Idea #8 – Create Data Backups

In the event that something happens and you lose precious computer data, having backups would make the experience more tolerable.

Create Data Backups

You can use Time Machine and an external hard drive or another device to create a data backup that updates automatically.


Idea #9 – Avoid Shady Websites

There is no need to click on a link that seems suspicious. Even if you receive one from a friend or family member that you know and trust, risking it is not worth it.

Also, while you are browsing and looking to download a particular file, such as a PDF book, avoid illegal sources as well as torrents.
