If you’re using a Mac, you probably think your general security is already superior to that of Windows PCs. In many ways, you’d be right to think this, but in the modern world of computing you can’t afford to be complacent; as the threats to your Mac’s security are more prevalent than ever before.

Thankfully, Apple has made your general and internet security for Mac as strong as possible, but you’ll have to make sure you do your part too. When it comes to business, keeping your valuable information secure should always be a high priority and not something ever overlooked.

To help you take your Mac internet security to the next level we’ve highlighted the very best practices for you to follow. Have a look at our list of 5 Mac security tips to learn more or head over to our Workplace page to read some of our other recent articles there.

Always install the latest software and security updates

If you’re someone that likes to postpone their security updates to a more convenient time, you’re going to need to re-evaluate your position on this bad habit.

It’s crucial that you hit ‘Install’ immediately, whenever you see the Software Update window appear on your Mac’s screen. Why? Well, having unpatched software on your computer opens you up to a whole host of potential cyber-attacks.

To ensure you’ll always be prompted to install the latest software and security updates for your Mac, open the Software Update pane inside System Preferences. Once there, make sure that “Check For Updates” checked and is set to the most frequent amount of time possible. This is normal, by default but it’s worth having a look at just to make sure.

Make sure you don’t forget to back up your data with Time Machine

With everything being transferred to cloud in recent years, the value of hard backups has slowly been overlooked. Sadly, solely relying on iCloud to store your valuable data can leave you open to attacks from hackers and seriously jeopardise your internet security for Mac.

Thankfully, Time Machine offers a robust solution for keeping your valuable data safe in the way of a hard backup. To create a Time Machine backup, plug in your desired drive and then click on the Time Machine pane in order to start the process.

Enable Keychain and up your password security

When it comes to Mac internet security, having the strongest passwords possible is a vital part of keeping yourself safe online. By this point in time, you should in no way be using the same or similar passwords for anything online.

However, when dealing with a large number of complex passwords, remembering them as and when required can be a burdensome challenge.

With Mac OS X, you can conveniently store all of your complex passwords, certificates, and other confidential login information securely, by making use of the Keychain feature. To access and enable the Keychain feature, go to the Utilities folder in Applications.

Turn on your firewall

In the past, you would often hear how your internet security hinged on whether you had a good firewall or not. But, the importance of having a good firewall hasn’t really changed over the years, as they continue to fend off unwanted incoming network connections to this day.


Strangely, your firewall internet security for Mac is actually disabled by default. However, it couldn’t be easier to enable the firewall and doing so is the best course of action if you want to maintain your Mac security.

To enable your firewall, find the Firewall pane in your Mac’s System Preferences. Once there, you’ll need to click the padlock icon in the bottom left of the pane and then type in your login information when prompted. After this, simply click the “Turn On Firewall” button.

For an added layer of security, click the “Firewall Options” button and then check the “Stealth Mode” box. By doing this you’ll be able to hide your computer on public networks, like WI-FI hotspots or libraries.

Encrypt your user data with FileVault

You’ve probably heard of encryption through a TV show or movie if you don’t already utilise it. Thankfully, it’s not just government agencies that can reap the benefits of data encryption; you can too.

By turning on your Mac’s FileVault feature, all of the files in your Mac’s user account can be securely encrypted. Then, in order for the files to be opened, you’ll have to enter your account password or the secure recovery key that’s created when you enable FileVault.
