A dialogue box appears every time on startup

Everytime I start my MacBook, I get a dialogue box which says - Do you want the application "mediasharingd" to accept incoming network connections?


It stays for a few seconds and disappears even before I read it. What is the reason?


MacBook Pro 13", macOS 10.15

You have your Firewall enabled, so it is doing what you requested it to do.

It is part of the OS, so allow or deny as you wish.


If your network is behind a NAT router, you don't need the Application Firewall.

If you connect to public wifi with multiple sharing services enabled, you might get some benefit from turning on the Firewall at those times instead of disabling all of the sharing services.

If you don't enable anything in the Sharing system prefs, then you don't need a Firewall.
