    Hi there

    Is it possible to prevent apps from accessing internet without little snitch?

    Any solution that works natively in macOS/ Mojave?

    What I can think of is modifying the hosts file, but that assumes you know everywhere the app is trying to access.

    There is a Firewall in macOS, but it's not fantastic. You can use it to block incoming connections to an app, but I don't think you can use it to block outgoing connections.

    Can you provide more specifics on exactly what you're trying to do.

    You might tell us which specific apps you are concerned about.
    Some apps need that internet connection, and don't provide a good result without it.

    Even using Little Snitch (or other software that identifies apps and processes that are "calling home") can be set too strictly, and can interfere with your internet connection when there is no need to do that.

    That’s not correct. macOS has a full-featured and quite powerful firewall, PF (https://en.wikipedia.org/wiki/PF_(firewall)),and some of the apps are just a GUI to control it. Murus for example; https://murusfirewall.com/.

    Anyone know, how to block outgoing connection on particular applications using Mojave's built-in firewall?
