Run the installer on windows, which should be pretty straight forward.
You can open the
.dmg file and drag the "turboget" app to "Applications"
However, you may get an error about the application being from an "Unidentified Developer" (this is expected, because you need to be part of Apple's developer program to sign applications, which costs $100 which isn't feasible for a hobby project).
You will have to go to "Settings > Security and Privacy" and you should find a button to open the application. Thankfully, you only need to do this once.
