@t-joave How do you make the connection? I'm trying to make it but the server returns [] nw_endpoint_create_with_peer_name getpeername failed [22: Invalid argument] [] tcp_listener_accept_locked tcp_connection_create_inbound() returned non-zero Program ended with exit code: 9

In your response you said Any Apple URL schemes that are not officially documented **should** be considered private API. That's why I'm asking, because these documentation was written in 2017. The use of App-Prefs:root=path is avoided but what about the use of App-Prefs:to open settings app? the difference is root=path Thanks to you.

Seems to be simple, but users complain about it, so should be not so simple
