MacOS Local network access issue

[Skepller]

Currently, my application requires access to devices on a user's local network. On Windows, users typically encounter a firewall prompt when they first run the app. However, the same doesn't seem to happen on Mac.

One user discovered that running the Client4JLauncher within the app, the application launches through a Terminal and this prompts Mac to ask for permission to allow "Terminal" to access the network, which resolves the issue. Yet, when the app is launched normally, it seems to be blocked from network access and immediately fails with the error java.net.NoRouteToHostException: No route to host.

The user did capture videos demonstrating the issue:

• Popup when using Client4JLauncher
• Both versions connect attempt

I'm a bit stumped on what can I do to fix that, any ideas?
