How to run hardware test with Lion?

Hello,


From the instllation of Lion we've lost the chance to run the harware test. Cmd-R takes you to the Recovery partition, where there is no way to make any Hardawre test.


I need to test RAM, any idea? And... why Apple has wiped the startup option to make hardware test?

iMac, Mac OS X (10.7), 21".5, 8Gb RAM, i5@3.6 Ghz

you use the original install DVD that came with your Mac to run AHT.

Note: Some Macintosh computers that shipped with OS X Lion support the use of Apple Hardware Test over the Internet. These computers will start up to an Internet-based version of AHT if the hard drive does not contain AHT.


I hope that my Mid 2010 iMac is in the list... Now I'm far from the iMac, but it seems that the D key had no effect. I don't remember if the Internet connection was active at that very moment.


I'll give it a try.


Thanks!

Right you are Fortuny..I and three of my friends who all own 2010 Macs of different configurations tried to run a hardware test, and nothing happend for any of us when pressing the D key. The applications disc that came with your computer is the answer for doing an AHT. Thanks for stating it so clearly for the rest of us!

The magic words are "Macs that shipped with OSX Lion" and your 2010 iMac is thus definetly not on that list 😟


Neither is any of my own Macs.

Tess888,


Well, that's not all true. What I did, as suggested in this thread, an installation of AHT from my original Snow Leopard DVD; now I'm far from my iMac, but I can tell you that I've found a AHT.pkg file, installed, restarted and pressing D at boot I haf my AHT back!!!


I looked for the file using Terminal, and I copied it on my Desktop; a double click to install and here you go.

How did you do that? I really need to check my hardware but since I purchased Lion on the Mac App Store the AHT vanished from my system. I have the original Mac OS X installer DVD but I don't know what key to press to start it from the disk and I don't know how to extract the file from it either.
