Summary of the Article: The Importance of Firewall on a Mac
1. A firewall is necessary to protect your Mac. A firewall acts as a barrier between your computer and the internet or a network, preventing unwanted contact from other computers.
2. Mac devices can still allow access through the firewall for certain services and apps. While a firewall provides protection, some services and apps may still have access to your Mac.
3. It is safe to use a firewall on a Mac. Even though Mac devices are generally secure, a firewall adds an extra layer of protection against unwanted connections from other devices on the internet or network.
4. Leaving the firewall on is recommended. Newer firewalls have minimal impact on speed and system resources, so it is advised to leave the firewall on for added security.
5. A firewall is less important on a Mac compared to a Windows-based system. macOS does not allow potentially vulnerable services to listen for incoming connections by default, reducing the need for a firewall.
6. Without a firewall, your home network is vulnerable. Not using a firewall leaves your network open to every connection, making it difficult to detect and protect against incoming threats.
7. Mac has built-in antivirus software. macOS has state-of-the-art antivirus software to block and remove malware, providing protection for your system.
8. To make your Mac more secure, follow these steps:
- Use secure passwords.
- Create passkeys.
- Require users to log in.
- Secure your Mac when it’s idle.
- Limit the number of administrative users.
- Encrypt the data on your Mac with FileVault.
9. Turning off the firewall increases the risk of unauthorized access. Disabling the firewall can make your device and network more vulnerable to security breaches.

Is it safe to use firewall on Mac
Even though Mac devices are known for their secure nature, that doesn't mean that it's best for organizations to leave the firewall in its default state. A firewall can still protect Mac devices from unwanted connections that are initiated by other devices on the internet or local network.
Should firewall be on or off
Newer firewalls on both PC and Macs are checking each packet in micro-seconds, so they don't have much drag on speed or system resources. Turning them off won't give you any real benefit, so it's better to leave them on and have that extra layer of protection.

What is the risk of turning off firewall
Turning off Microsoft Defender Firewall could make your device (and network, if you have one) more vulnerable to unauthorized access. If there's an app you need to use that's being blocked, you can allow it through the firewall, instead of turning the firewall off.
What happens if I leave my firewall off
Disabling a firewall permits all data packets to entering and exiting the network unrestricted. This includes not just expected traffic, but also malicious data — thereby putting the network at risk.
Is it OK if I turn off my firewall
Turning off Microsoft Defender Firewall could make your device (and network, if you have one) more vulnerable to unauthorized access. If there's an app you need to use that's being blocked, you can allow it through the firewall, instead of turning the firewall off.
When should I turn on my Mac firewall
When your Mac detects an attempt to connect to an app you haven't added to the list and given access to, an alert message appears asking if you want to allow or deny the connection over the network or internet. Turn on the firewall on your Mac to prevent unwanted connections from the internet or other networks.
Why you should turn off firewall
