How to Keep Your Mac Computer Secure in 2021


Alex Kassian How to Keep Your Mac Computer Secure in 2021

Cybersecurity doesn’t have to be complicated. You can easily protect your Mac and your most sensitive data in a few simple steps. 

Macs do have built-in security settings, but they’re often not used effectively — leaving your data and privacy vulnerable to attacks. Even if you turn on all of Apple’s security features, it’s not enough to keep your Mac 100% secure against the latest malware.

Here are a few things you should be doing to secure your Mac and personal information from the most advanced cybersecurity threats in 2021.

10 Things You Should Do To Protect Your Mac

1. Keep Your OS X & Programs Updated

Keeping your Mac software and programs updated is possibly the simplest and most straightforward way of keeping your Mac safe from hackers. Cybercriminals target outdated software because they know where to find security vulnerabilities that developers only patch in updated versions.

It’s very easy to update your macOS software to the latest OS X version. Simply click on the Apple icon on the top left of your screen, select About This Mac > Software Update, and proceed with the installation instructions.

Once you’ve installed the latest macOS software, you can set future OS X updates to be installed automatically. Go to the  section in the System Preferences and select

Keeping all of your programs and apps updated is also very easy. Navigate to the App Store tab in your System Preferences and ensure that the and the are selected.

2. Change the Default Security & Privacy Settings

Your Mac might have some default settings that allows Apple and other apps to share and view your data, including usage data and location.

First, navigate to the Security & Privacy section in System Preferences. Under the General tab, you’ll be able to set a password for your Mac, stop automatic logins, and change the time it takes for a password to be required after your Mac goes into sleep mode. Having a secure device password is one of the safest (and easiest) ways to keep your data safe.

There are also a few privacy settings that you should address. Under the Privacy tab, you’ll see all of the apps that have access to your data, including your location, contacts, calendars, and more.

You’ll also see if you’re unknowingly sending usage data to Apple by clicking and deselecting the appropriate settings Simply uncheck the apps that you don’t want accessing your data, and choose whether you want your Mac usage data to be automatically sent to Apple.

3. Use a Mac Antivirus (That Actually Works)

There are many antiviruses out there, but a lot of them are not good at protecting against macOS-specific malware — especially now as hackers are specifically targeting Macs with advanced malware.

Apple’s built-in security features aren’t enough to keep your Mac 100% protected against threats like:

Antiviruses like Intego and Airo AV are purposely designed to protect Macs from a huge range of threats, including ransomware and online attacks.

When choosing a Mac antivirus (that actually works), you need to look for certain features which will help keep your computer safe:

4. Use a Privacy-Focused Browser

Staying safe and securing your privacy while browsing online can be difficult. Apple’s built-in internet browser, Safari, isn’t the most secure in terms of online safety and privacy — you’ll still be left vulnerable to malicious sites and phishing attacks.

Other popular browsers like Google Chrome won’t really protect your privacy either.

Using an alternative secure browser is one of the best ways to stay safe online. A few secure browsers are:

These privacy-focused browsers have built-in tools to ensure websites aren’t tracking your browsing activity or your IP address — trying to find your physical location. Brave’s browser also blocks malicious scripts that are hidden in scam websites that can hack your device without you knowing.

5. Use an Ad & Tracking Link Blocker

The browsers I previously mentioned are the best for security and privacy, but you might just want to stick with your usual browser. In this case, you can install Safari or Google Chrome browser extensions that are just as effective at protecting you online.

These extensions block all ads and stop websites from tracking your browsing activity across the internet. They also work to protect you from phishing websites — sites designed by hackers to imitate popular websites, encouraging you to input your login details so they can steal your accounts and personal information.

Many antivirus brands include easy-to-install ad blockers and tracking link browser extensions in their packages, such as Avira’s Safe Shopping or Norton’s Safe Web.

6. Install a VPN (Virtual Private Network)

VPNs disguise your original IP address and replace it with an IP address in an entirely different location. This means that hackers and websites cannot trace your connection and find your exact location, making you completely anonymous online. VPNs also encrypt your browsing data, so even if hackers could spy on you, they wouldn’t be able to see what you’re doing.

VPNs are used for a lot of different reasons — one of the most popular is being able to access geo-restricted content. For example, certain Netflix shows can only be watched in the UK. So, to bypass this geographical restriction, you can use a VPN to change your IP address location to the UK and log in to view the UK’s Netflix content.

While you can install standalone VPN apps like NordVPN, many antivirus packages like Norton 360 and TotalAV include high-quality VPNs in their Mac antivirus packages.

7. Use a Password Manager

What are you doing to keep all of your account passwords constantly updated to ensure they’re safe? As mentioned previously, using a secure password to lock your Mac is essential. But what about when logging into accounts online, such as your social media profiles and online banking portals?

Apple offers its own password manager — iCloud Keychain. It works by saving and securely storing your account login credentials, passwords, and payment card information. All information is encrypted with AES 256-bit encryption, also known as “military-grade encryption”.

While iCloud Keychain can be useful, it is limited — it can only be used for Apple products, like Safari. This means you won’t be able to use it to log into websites using an alternative browser.

Also, unlike other password managers, it won’t warn you if your passwords are compromised in a data breach. You also won’t have the ability to instantly keep passwords updated with one click, meaning you’ll have to change them one-by-one.

There are many great alternative password managers for Mac. One particularly good one is Dashlane, which lets you log into almost any app or website using any browser you choose. Dashlane also lets you instantly turn all of your old and weak passwords into new and complex passwords, with just one click.

8. iCloud Two-Factor Authentication

Two-factor authentication (2FA) is where you’re required to input a randomly generated one-time code along with your account password when logging into your accounts.

Two-factor authentication adds an extra layer of security by stopping hackers from accessing your data, even if they know your passwords, as they won’t be able to guess the randomly generated one-time password.

While you should set up 2FA on all of your online accounts, you should first use it to secure your iCloud account.

You’ll be asked to input your phone number to receive the two-factor authentication codes.

Once set up, you’ll now receive a one-time password every time you log into your iCloud account on a new device or when logging in online.

9. Encrypt Your Files

Encrypting your files basically means securing your data behind a password. For example, a thief or hacker wouldn’t be able to access personal information and sensitive documents on your device if they’re encrypted and require a password to unlock them.

Apple has a built-in encryption tool, named “FileVault”, which makes securing your most sensitive personal information very easy.

Simply go to System Preferences > Security & Privacy > FileVault > Turn On FileVault. To avoid forgetting the encryption password and losing access to your files, you’ll be given the option to use your iCloud account to decrypt your files and reset your encryption password if you forget it.

Alternatively, you can create an encryption key. But you must keep a record of the encryption key somewhere safe, not on your device.

10. Backup Your Files

Regularly backing up your files ensures that you’ll always have a copy of your files if something happens to your Mac, including if it gets lost, stolen, or needs repairs.

Apple makes backups easy with its Time Machine feature. Time Machine is used to regularly back up your files on a separate hard drive so that you can restore your Mac and data from any recent periods.

Mac-based antivirus Intego also includes a backup feature that offers better functionality than Time Machine. With Intego, you can:

Time Machine is known for taking up a lot of hard drive space. But it’s recommended you use both Time Machine and another backup tool, like Intego’s Personal Backup feature, just to be extra safe.

Securing Your Data is More Important Now Than Ever

While cybercriminals have been targeting more and more Mac users recently, making simple changes like the ones described in this article can help you to fully safeguard your Mac and data from being stolen.

Having a Mac antivirus that provides proper protection is probably the most important thing you can do to secure your mac. For more information, see our list of the best 5 antiviruses for Macs in 2021.

Frequently Asked Questions — How To Keep Your Mac Secure

How long do macOS software updates take?

The time it takes for your macOS software to install depends on the speed of your device. Updates can sometimes take a few hours for the installation to fully complete.

For newer Macs, an update can take around 30 minutes to complete.

Before you update your Mac, it’s essential that you backup your data in case the installation fails.

What is the best antivirus for my Mac?

Some of the best antiviruses for Mac include Intego and Airo AV. These antiviruses are designed specifically for Mac and keep devices safe from Mac-based malware and viruses.

When choosing a Mac antivirus, you need to make sure the antivirus will protect you against:

Macs do have security features built-in to the macOS software. However, these security tools aren’t enough to fully protect you from hackers and malware. So choosing an effective Mac antivirus is necessary.

Before choosing a Mac antivirus, you need to know the best Mac antivirus programs available.

How does a VPN protect Mac?

A virtual private network (VPN) reroutes your Mac’s internet connection through a secure and private server — instead of the server provided by your internet service provider (ISP) who can track your online activity.

You must choose a VPN service provider that guarantees 100% privacy. Some VPNs (like almost all free VPNs) don’t have a “no-logs” policy, meaning they store your online activity, which could be shared with third-parties. Some also fail to fully protect your IP address, meaning websites can still track your true location.

VPNs can be installed as standalone apps, but many of the best antiviruses now include secure, no-log VPNs with their software.

Can Apple track how I use my Mac?

Yes, unless you change your Mac’s default privacy settings. Apple wants to track your Mac usage to help with their product development, so your Mac computer comes with this option already enabled.

Apple can also do other things like track your location and iCloud usage.

You need to change your privacy settings so Apple no longer has this access.
