Apple Service Diagnostics (ASD) is only distributed to Apple Service Providers. The Apple Service Diagnostics application is designed to run both EFI and Mac OS X tests from an internal cd- or dvd-drive or an external USB hard drive ( version 3s123 or above ). Apple Service Diagnostics (EFI) runs low-level tests of the hardware directly and does not require Mac OS X, while Apple Service Diagnostics (OS) uses Mac OS X to run tests.

This diagnostics suite was added to the ASD archives 11-Jun-2013

Note: ASD is tested with a custom Mac OS that is supplied in the image. As a test requirement the OS is set up as a root user. DO NOT copy ASD to another OS or some tests will fail. Also running ASD on another OS removes some of the Finder menu items and sets preferences specifically for ASD requirements. It will damage your OS so use the one provided.
