The Apple Hardware Test (AHT) is a special bootable diagnostic tool that can test a Mac’s hardware. AHT has been included with Macs since well before the Intel Macs made an appearance.

AHT was originally distributed on CDs, then DVDs, and finally on USB flash drives, for Macs, such as the MacBook Air, that don’t have an optical drive.
