As we grow increasingly connected to the internet, security is becoming more important than ever. Firewalls on our computers have existed for a long time, but sometimes, it can actually be more problematic than useful, which is why turning it off can actually be a good thing. But before we decide to turn it off, what exactly is a firewall and what does it do?

What Is A Firewall?

A firewall can be thought off as a wall of bricks surrounding our home. This wall helps to keep unwanted visitors out while protecting the residents of the home. In tech terms, it helps to protect your computer from unwanted intrusions from the likes of hackers or malware which might be trying to compromise your system and gain access to your personal information.

It will scan incoming internet data for things that are known to cause problems, and thus prevents it from infecting your computer system and causing havoc.

Firewall VS Antivirus

So right off the bat, firewalls sound a lot like antivirus software designed to protect your computer from threats, but there are differences. Having a firewall does not negate the need for antivirus software, even though it does protect your computer to a certain degree.

In the case of antivirus, you can think of it like a metal detector of sorts. Imagine a bad person was at the airport and they were looking to fly somewhere, so they use a fake passport and somehow get past immigration (firewall). Now that they’re inside the airport, they will need to go through a metal detector (antivirus) that will pick up any illegal objects like knives or guns they might be trying to smuggle on board.

Antivirus also works great for computers or devices that aren’t connected to the internet, where if you try to load a program from a disk or a USB drive that has malware, it will pick up on that.

Why Would You Want To Turn Off Your Firewall?

With that being said, it sounds like having a firewall is a great thing, doesn’t it? But that doesn’t mean that it doesn’t run into issues every now and then.

This is because computers pretty much just do what they’re told to do, they’re generally not smart enough to think on their own.

This means that as long as an action, connection, or program has been deemed as “bad” (or even “risky”), it will block it, even though it might not necessarily be the case.

For example, system administrators might need to do some work like applying software updates or installing new applications, and sometimes a firewall might prevent them from doing that.

As an end-user, you might also run into similar issues where programs or applications may run incorrectly or not at all due to their connection being blocked, and this is why you might want to turn off the firewall.

IMPORTANT: Most app developers will have a guide for users that bump into a Firewall issue. We recommend trying that first, as disabling the Firewall greatly increases your security risk. But if you’re set on disabling the Firewall, please continue reading…

Apple T2 chip.
The next generation of security.

Apple Mac Firewall

The Apple T2 Security Chip — included with many newer Mac models — keeps your Mac safer than ever. The Secure Enclave coprocessor in the Apple T2 chip provides the foundation for Touch ID, secure boot, and encrypted storage capabilities. Touch ID gives you a seamless way to use your fingerprint to unlock your Mac, fill passwords in Safari, and make purchases with Apple Pay. Secure boot helps ensure that you are running trusted operating system software from Apple, while the Apple T2 chip automatically encrypts the data on your Mac. So you can be confident knowing that security has been designed right into the architecture of your Mac, from the ground up.

Apple helps you keep your Mac secure with software updates.

Firewall For Mac Osx

The best way to keep your Mac secure is to run the latest software. When new updates are available, macOS sends you a notification — or you can opt in to have updates installed automatically when your Mac is not in use. macOS checks for new updates every day, so it’s easy to always have the latest and safest version.

Protection starts at the core.

The technically sophisticated runtime protections in macOS work at the very core of your Mac to keep your system safe from malware. This starts with state-of-the-art antivirus software built in to block and remove malware. Technologies like XD (execute disable), ASLR (address space layout randomization), and SIP (system integrity protection) make it difficult for malware to do harm, and they ensure that processes with root permission cannot change critical system files.


Download apps safely from the Mac App Store. And the internet.

Now apps from both the App Store and the internet can be installed worry-free. App Review makes sure each app in the App Store is reviewed before it’s accepted. Gatekeeper on your Mac ensures that all apps from the internet have already been checked by Apple for known malicious code — before you run them the first time. If there’s ever a problem with an app, Apple can quickly stop new installations and even block the app from launching again.

Stay in control of what data apps can access.

Apps need your permission to access files in your Documents, Downloads, and Desktop folders as well as in iCloud Drive and external volumes. And you’ll be prompted before any app can access the camera or mic, capture keyboard activity, or take a photo or video of your screen.

FileVault 2 encrypts your data.

With FileVault 2, your data is safe and secure — even if your Mac falls into the wrong hands. FileVault 2 encrypts the entire drive on your Mac, protecting your data with XTS-AES 128 encryption. And on Mac systems with an Apple T2 Security Chip, FileVault 2 keys are created and protected by the Secure Enclave for even more security.

Designed to protect your privacy.

The most secure browser for your Mac is the one that comes with your Mac. Built-in privacy features in Safari, like Intelligent Tracking Prevention, help keep your browsing your business. Automatic strong passwords make it easy to create and use unique passwords for all the sites you visit. And iCloud Keychain syncs those passwords securely across all your devices, so you don’t have to remember them. You can also easily find and upgrade any weak passwords you’ve previously used (and reused and reused and reused).

Automatic protections from harmful sites.

Safari also helps safeguard you against fraudulent websites and those that harbor malware — before you visit them. If a website seems suspicious, Safari prevents it from loading and notifies you. And when connecting to unencrypted sites, Safari will warn you. So everything you need to browse without worry is right at your fingertips.

Find your missing Mac with Find My.

The Find My app combines Find My iPhone and Find My Friends into a single, easy-to-use app on Mac, iPad, and iPhone. Find My can help you locate a missing Mac — even if it’s offline or sleeping — by sending out Bluetooth signals that can be detected by nearby Apple devices. These devices then relay the detected location of your Mac to iCloud so you can locate it in the Find My app. It’s all anonymous and encrypted end-to-end so no one — including Apple — knows the identity of any reporting device or the location of your Mac. And it all happens silently using tiny bits of data that piggyback on existing network traffic. So there’s no need to worry about your battery life, your data usage, or your privacy being compromised.

Keep your Mac safe.
Even if it’s in the wrong hands.

All Mac models with the Apple T2 Security Chip support Activation Lock — just like your iPhone or iPad. So if your Mac is ever misplaced or lost, the only person who can erase and reactivate it is you.
