10 Tips for Securing Sensitive Information on a Mac

Apple sold more than 20 million Macs in 2020. Those numbers were even higher the following year.

Hundreds of millions of people rely on a MacBook every day. They are fast, powerful, and reliable. And with a few basic security steps, they are one of the least likely devices to be hacked.

But there’s always a risk. Whether your Mac is physically stolen or a hacker gains access to your computer, your sensitive information might be at risk.

Wondering what your Mac security options are? Luckily, there are a few quick and easy steps you can take right now to protect information on Mac computers. Keep reading below for 10 important Mac security tips.

1. Set a Mac Login Password

When you set up a Mac computer, you’ll need to create a device passcode. This passcode is just a few digits long, but it’s essential.

This passcode is used to make any changes to your device. Not only that, but that passcode can be used to lock your computer completely, preventing anyone from using it while you aren’t looking.

To lock your computer using your passcode, visit System Preferences, then click on Security and Privacy.

Click “Require Password” and set a time limit. After a few minutes of inactivity, the computer can lock, preventing anyone from accessing it while you’re in the break room, out on a phone call, or if the device was stolen.

2. Disable Automatic Login

When you start up your Mac, by default, it logs you into your admin account right away, as opposed to additional user accounts. This can be convenient but also poses a threat.

Anyone who can take your computer will be able to log in simply by turning the computer off. Luckily, you can disable automatic login to prevent this.

By visiting the same menu in your System Preferences, you can see which user will be logged in automatically, and you can disable this function altogether to prevent automatic logins.

3. Password Protect Your Hard Drive

Your hard drive stores all of the information on your computer. And you can easily keep that information private and secure by encrypting it. This makes the data inaccessible to other users who are trying to snoop.

To encrypt your data, visit System Preferences, click on Filevault, and enable Filevault using your admin password.

4. Password Protect Folder

We all have documents on our computers that contain sensitive information, such as tax returns or medical records. So how can you ensure data protection on your Mac? You can create a password-protected folder.

Add any documents you want to keep private to a folder on your Mac. Then set up a password, so nobody can access those files unless they know the password. See here how to set that up so that you’re files are easily accessible to you but locked away from everyone else.

5. Find My

You can take every measure to protect the contents of your computer, but sometimes, it’s hard to protect the computer itself. Macs are very valuable and are often the target of theft.

If your MacBook leaves the house often, such as bringing it to your workplace, to a coffee shop, or on a plane, your chances of having your computer stolen or leaving it behind somewhere are higher.

Luckily, you can always keep tabs on your Apple devices using the “Find My” app.

With the app, you can track the location of your MacBook using your iPhone and vice versa. So if you can’t find your Mac, you can use the app to discover that you left it in a friend’s car, at home, or your favorite coffee shop.

6. Remote Data Wiping

If you use the “Find My” app and discover that your computer was stolen, the last thing you want to do is try to get it back yourself. Your life may be in danger.

You can alert the authorities, but there’s a chance they won’t do anything since it’s just petty theft. While you might not get the computer back, you can prevent anyone from gaining access to your data.

With the Find My app, you can use your Apple ID to remotely erase the data on that device.

You lock down the device so that nobody will be able to activate the device without your Apple ID. So even though they may try reselling the device, it will be apparent that it was stolen and unuseable.

7. Use the Firewall

To block most hacker attempts that would try to access your computer and information remotely, you can set up a firewall. Macs have this functionality built-in.

Just visit the Security and Privacy tab in your preference menu. Click on the Firewall tab. All you need to do is turn on the firewall. This may require your system password to either enable or disable.

8. Use Antivirus Software

Mac is good at repelling viruses and malicious software on its own. Luckily, you can install third-party anti-virus software to increase your computer’s defenses.

Just visit the app store from your Mac, and scroll through the available options. Most good options require payment. But the level of security offered is often worth it.

9. Use a Password Manager

It’s essential to use different passwords for every account you create on the internet. Using the same password over and over again puts you at risk.

You can use a browser extension tool that acts as a password manager to make this process easier. So you can create unique passwords for all of your accounts, save them, and access them all using only one master password.

10. Don’t Click Bad Links

One of the most important things you can do to keep your information secure is to practice good internet hygiene. One of the most common scams is phishing.

It’s when a hacker creates a link that looks authentic, entices users to click it, and gains access to that device through malicious software.

Learn what phishing links are and how to spot them, and avoid clicking on anything suspicious.

Protect Your Sensitive Information at All Costs

Cybersecurity is critical, not just for big businesses but also for individuals. If hackers can gain access to bits and pieces of your personal, sensitive information, they could eventually gain access to important accounts, such as bank accounts, or steal your identity.

Neither is something you ever want to deal with. Keep your Mac safe and avoid these problems altogether.
