// A custom apphost is required (instead of just invoking <arch-dir>/OpenRA directly)
// because macOS will only properly associate dock icons and tooltips to windows that are
// created by a process in the Contents/MacOS directory (not subdirectories).
//
// .NET 6 does not support universal binaries, and the apphost that is created when
// publishing requires the runtime files to exist in the same directory as the launcher.
