A firewall can protect your Mac from unwanted contact initiated by other computers when you’re connected to the internet or a network. However, your Mac can still allow access through the firewall for some services and apps. For example:
If you turn on a sharing service, such as file sharing, macOS opens a specific port for the service to communicate through.
An app or service on another system can request and be given access through the firewall, or it might have a trusted certificate and therefore be allowed access.
For greater control, you can select apps and services, and specify whether they can have access through the firewall.
On your Mac, choose Apple menu > System Preferences, click Security & Privacy , then click Firewall.
If the lock at the bottom left is locked , click it to unlock the preference pane.
Click Turn On Firewall.
To specify additional security settings, click Firewall Options and do any of the following:
Allow only specified apps and services to connect: Click the Add button , then select the app or service in the dialog that appears.
Allow only essential apps and services to connect: Select the “Block all incoming connections” checkbox.
Automatically allow built-in software to receive incoming connections: Select the “Automatically allow built-in software to receive incoming connections” checkbox.
In your opinion, is turning on the firewall inconvenient or beneficial? Happy wheels
An application or service on a different system may request and be granted access through the firewall, or it may possess a trusted certificate and thus be granted access.
Through the firewall, an application or service running on a different system can request and be granted access, or it may be granted access because it possesses a trusted certificate.
You may choose which services and apps to allow access over the firewall, giving you more control. space bar clicker
