Firewall is software that’s there to protect you so it’s best to keep it turned on. With Firewall running, your Mac takes care of everything — automatically determining whether or not an application is allowed to send or receive traffic from the network. It does this using Code Signing Certificates that are issued to trusted applications. Without the proper certification, an app isn’t allowed through. Think of it like a bouncer on the door of a club — if an app doesn’t have the proper ID it ain’t coming in.
There may be times where Firewall isn't needed, though. Say, for example, you’re playing a video game and don’t want to access the online multiplayer modes. Or antivirus software that you’ve installed is conflicting with Mac’s Firewall application.
Turning off Firewall solves these problems. But you should be aware that, while switching off Firewall can stop apps on your computer from sending traffic to the network, it provides free reign for incoming connections, leaving you vulnerable to malware and hackers.

Clean your Mac before changing settings
Before we show you how to turn Firewall on and off, it’s recommended that you have a cleanup of apps on your system, particularly those that you’ve previously deleted. If you’ve ever downloaded an app by mistake and uninstalled it or found an app to be malicious and sent it to the Trash, there’s every chance that their remnants still exist on your system.
If that’s the case and you have Firewall switched off, these apps will be able to send and receive traffic, putting your Mac at serious risk.
So, if you plan on playing around with the Firewall settings, use a tool like CleanMyMac X to find and remove any unwanted files that exist on your system. CleanMyMac scans all of your disks and compiles installed apps. It also identifies broken and outdated apps so that you can easily remove them.
Here’s how to use it:
- Download and launch CleanMyMac X. (Free download)
- Click on the Uninstaller tab.
- Click on View All Applications and select any apps that you wish to remove from the list. Apps can be sorted by Name, Size, Selection, and Last Launch Date to help your search.
- Click on Complete Uninstallation from the dropdown menu.
- Click on the Uninstall button and enter your admin password when prompted.
Selected apps will now be completely removed from your system.
Okay, with that out of the way, let’s get into enabling and disabling Firewall.
How to turn on Firewall on Mac
Mac’s Firewall settings can be found in the Security and Privacy preference in System Preferences.
To enable Firewall in macOS and OS X v10.6 or later:
- Go to System Preferences > Security & Privacy.
- Click on the Firewall tab.
- Click on the lock icon in the bottom left corner of the window and enter your administrator password.
- Click Turn On Firewall (or Start in OS X).

By clicking on the Firewall Options button (or Advanced for OS X) you’ll find additional settings that give you more control over how the Firewall performs.
In the list, you’ll see all of the apps that are currently allowed to send and receive network traffic. By clicking on the application to highlight it and hitting the '-' button, you can remove an app from the list. Alternatively, clicking on the '+' button lets you add a new app to the list.
You’ll also be presented with three options:
- Block all incoming connections — this blocks all connections other than those required for basic internet services.
- Automatically allow signed software to receive incoming connections — this automatically allows software signed with a valid certificate to gain access to the network for sending and receiving traffic.
- Enable stealth mode — this prevents Mac from responding to probing requests.
Check the boxes for any settings you'd like to enable and hit OK to confirm.
The great thing about Firewall for Mac is that it takes care of everything for you, regulating the access of apps to the network to keep your system safe from malicious activity. As said, it’s best to keep Firewall turned on and let it does its thing. But if you do plan on turning it off, even just for a short time, run CleanMyMac X prior to doing so to rid your Mac of old apps lurking in the depths of your system.

Backup your Mac before installing the new macOS
No matter which version of macOS Mojave you’re installing, you should backup your Mac first. You can do this via the Time Machine or with an app like Get Backup Pro (it’s more powerful than Apple’s Time Machine.)
Note: You need a backup of every important file that you'll want to reinstall on your new macOS. But there's no point in running a straight clone of your previous files: you'll just end up with the same junk floating around your new operating system.
So, before backup clean up your hard drive from junk data, old and useless data, and duplicates. An easy way to go about this is to get a Mac cleaning app like CleanMyMac. It will save to hours of manual file cleanup before the backup. Junk removal with CleanMyMac takes only a few minutes and absolutely safe for your Mac. The duplicate files finder like Gemini helps you to detect duplicate files on any folder, preview duplicate pictures, videos, music, archives, documents, and all other specific extensions, and get rid of useless versions.
You don't need to dig through Internet to search and and download each apps mentioned in this guide, all of them available on Setapp.
How to backup a Mac with Time Machine
Backing up your system with Mac’s built-in Time Machine feature couldn’t be easier.
- Go to System Preferences > Time Machine and check that it’s turned on.
- Under Select Backup Disk choose a hard drive to backup your system.
Time Machine will then perform automatic backups of your system and store them on your chosen hard drive for easy retrieval.
How to backup important data only with Get Backup Pro
Get Backup Pro offers a more comprehensive way to backup your Mac, allowing you to make copies of your system files in four different ways: simple copy, clone, incremental, and versioned. It’s a great app to use alongside Time Machine and lets you recover files to any computer — handy if anything goes seriously wrong with Mojave.
