Popular perception might lead you to believe that MacBooks and other Mac machines are safe and immune to viruses and other similar security problems… but don’t trust them. Macs are known to be vulnerable to viruses and even some of the security flaws that plague PCs. To put your mind at ease, here are some ways to improve your MacBook security.

Our first tip might have disappeared from your radar. As part of the Security features on your MacBook, you may have noticed something called FileVault. This is a setting that can help encrypt all the data on the main MacOS hard drive. With this, your data will be tampered with using the XTS-AESW 123 encoding standard. This makes it difficult for someone to access your files if your Mac is stolen.
FileVault is on Mac OS X Lion or later. You can access this by clicking on the Apple menu and choosing System preferences > Security and Privacy > FileVault.
When you activate it, you will always have to log into your MacBook with your account password. If you forget your MacBook password and want to unlock your data, you can use your Apple ID as an alternative to unlock it. However, if you forget your account password and FileVault recovery key, you won’t be able to log into your Mac or access your data on your startup disk. Any encoding you start will do so in the background as long as you are connected to AC power.
The firewalls they are something we talked about earlier for Windows machines. However, on Macs you can use the firewall similarly integrated sense to help control connections made to your computer from others on your local network. There’s a firewall in an integrated sense, and this basically helps prevent rogue apps from taking control of open network ports for apps you approved. Here we tell you how to use it.
Go to Apple menu, choose System preferences > Security and Privacy > Activate Firewall. After doing this, you can specify certain apps that you can connect or block, allow built-in apps to accept connections, or only downloaded apps. You can even choose stealth mode, which will make it harder for hackers and malware to locate your Mac.
Take note, we are calling the built-in firewall as firewall one-way because it only offers projections on incoming networks. You will need a paid outbound firewall for true protection against the most sophisticated attacks, as it notifies you about something you downloaded connecting to networks without your permission.
Officially, Apple assures The safest place to get apps for your MacBook is the App Store. All the apps that you find in the store are reviewed by Apple to make sure that there are no malware, viruses, or something else that could damage your Mac. Of course, there will come a time when you will need to download extra software from the Web that is not found in the App Store (such as Chrome, or Photoshop), so that Apple has established the privacy and security settings to authorize the App Store by default, as well as Identified Developers.
But if you really want your Mac to be super secure, you can change the settings to App Store only. Once you reach a point where you are sure that you are not going to download extra apps, this will guarantee that some of your downloads will not enter your system and will take over your Mac without you knowing.
You can change this setting by going to Security Menu and choosing System preferences > Security and Privacy > general, then go down to Allowed apps downloaded from. In this section you can change the settings so that only apps are downloaded from the App Store. You can also visit this page to allow exceptions via the button Open Any Way.
Our last tip might seem a bit obvious, but it’s worth mentioning. If you move away from your laptop, we suggest that you always keep it locked. Also that you enable the option to ask for a password once you “wake up” your Mac, or when the screen saver is activated.
You can set your Mac to log out when you’re not using it by going to the Apple Menu and choosing System preferences > Security and Privacy. From there, click Advanced, after Log out after … minutes of inactivity. We also suggest you go to Security and Privacy, after general, and select Ask for password … after screensaver starts.
Finally, we also suggest using Hot Corners. With Hot Corners, you can move your mouse to a corner of the screen to automatically lock your Mac. Visit Desktop & Screen Saver> Mission Control> Hot Corners. Then you can choose a modifier key (like a command) and one of the corners to lock the screen.
