Block incoming connection on apps on Mac

Hey, Thanks for reaching out to us.

Yes, you can. The firewall feature can be used to block all the incoming connections into installed applications on Mac. Please navigate to macOS->Security and choose the Firewall option. Check the ‘Enable Firewall’ option and choose the ‘Block incoming connections’ option under ‘Applications’. Click on the ‘+Add app’ icon and select the apps to which the incoming connections are to be blocked. Click ‘Done’. Associate targets and save the policy.

Kindly use the help link for more info on the same.

Cheers!
