A command line tool to make MacOS do things.
Install GraalVM java SDK and native image tool.
sdk install java 22.3.r19-grl
sdk use java 22.3.r19-grl
~/.sdkman/candidates/java/current/bin/gu install native-imageBuild the tool.
./gradlew nativeCompileFind the names of the network services in your mac.
networksetup -listnetworkserviceorder
An asterisk (*) denotes that a network service is disabled.
(1) Belkin USB-C LAN
(Hardware Port: Belkin USB-C LAN, Device: en7)
(2) Wi-Fi
(Hardware Port: Wi-Fi, Device: en0)

(5) VPN (L2TP)
(Hardware Port: L2TP, Device: )Run the tool in dry run mode, setting your user as the only expected user on the machine, and "Belkin USB-C LAN" as
primary and "Wi-Fi" as secondary. If you are not the only user logged into the machine, then add the
flag --exclusive-user-match=false to the command bellow in order to maintain the exacted behaviour.

11:51:07.811 [main] INFO macosctl.NetworkServiceOrderService - Not switching service order.Setting the network services in the same order as they are does nothing. To have the tool switch the order switch the
primary with the secondary network service. The commands that are explained here are all executed in dry-run mode,
which means the tool does not actually switch the services order, it only logs that information.

Run the tool in dry run mode, setting your user as the only expected user on the machine, and "ALERT" as primary mode
(for this example is the mode that is active) and "SILENT_ALLOW" as secondary. If you are not the only user logged into
the machine, then add the flag --exclusive-user-match=false to the command bellow in order to maintain the exacted
behaviour.
