iMac Firewall options config question?
I went into my firewall settings, im trying ti install a VPN on my router. Anyway, my options that are checked, I do not think are the default, and may be incorrect. For example, the apps, Garage Band, Relax Melodies, and the apple Webkit, I never put there, and missing I believe are some file and screen sharing preferences. I tried to add them, or return the selections to default, but I can not find out how. If there is a pretty simple way to do, preferably, please let me know. Below is a screen shot os its current config. Thank you.
P.S this is a 2017 27" 5k running Mojave
MacBook Air 13", macOS 10.13
