May 22, 2013 10:20 PMby mende1,If your Mac didn't come with DVDs, you can't get Apple Hardware Test in your hard disk anymore because it's only possible to get it starting your computer in this mode without being able to download it in OS X and copying it to a folder.

If you still have the original discs that came with the computer you can try running it from Disc 1. But once you chose to install Mountain Lion over your original system, then you lost the ability to run the AHT from the computer. I assure you this information has been around since 2008.

Before the process that I described above, I ran the AHT from the HD and not from Internet Recovery...
So, the assumption that AHT doesn't come packed in computers with ML installed, if true, doesn't apply to my Mac...

Sorry, that the Article was of no help to you.
