• Host Machine: A Mac running macOS Mojave (10.14.6) or Catalina (10.15.7). Why? AST 1.5.3 30 leverages deprecated kernel extensions (kexts) that Big Sur and later block.
• Bootable Media: The toolkit is distributed as a .dmg containing a bootable .iso or a Restore image. It must be written to a USB drive (minimum 16GB) using dd or Apple’s Restore utility.
• GSX Access: The toolkit requires a live authentication token from GSX. Without an active GSX account (which requires Apple certification), the toolkit will either refuse to boot or will enter a limited "demo" mode with no actual testing capability.
• Target Macs: Macs from 2012 to 2020 (pre-M1). This includes all Intel-based Macs up to the i9 2020 models. M1 Macs are NOT compatible with AST 1.5.3 30.
