  1. Double-click the downloaded DMG file to decompress it.
  2. Move the BX app to your Applications folder.
  3. Open BX from Applications and create your first launcher.

BX works on macOS 26 and 27. It is not available in the Mac App Store: an app that applies a seatbelt profile cannot itself be sandboxed.
