Intel Mac :: Start Hardware Test On Lion?
Mar 10, 2012
I have an iMac 20
2.66 Ghz Intel Core 2 Duo
2GB 800 Mhz DDR2 SDRAM
Running OS X - 10.7.3Â
Lately the machine is not detecting wireless keyboard, trackpad, and mouse unless the iMac is restarted. I tried to run the AHT using the restart and holding the D key but this doesn't seem to work I'm not sure how to run the AHT using the original DVDs, especially if the original OS was Leopard or Snow Leopard.Â

My computer started having problems some two weeks ago.First it was very slow then it blocked during the use of Photoshop.At that stage I used Apple jack to test and solve the problem and it worked.But two days later the problem came again as a verry slow start-up.I checked the disk and there was no problem signaled.I tried to boot the computer on the installation disk in order to execute the Hardware test...The test gave the folowing error code: 4HDD/11/40000004:SATA(0,0)Â

How can I run AHT on my iMAC 21.5 inch, MID 2011 and Mac OS X Lion 10.7.3 (11D50)? There were no DVDs in the package, no restart key-stroke combination connected to internet-aht, no aht is included in the package I bought and downloaded from Apstore. One of the 4 rear USB ports seems to be death from the very first moment. I would like to use the AHT to see if this is some SW misconfiguration or is it a HW problem.

recently I bought WD6400AAKS hard drive. I made to partitions (1st for OS and applications, 2nd one for photo files). I also did fresh OS install and loaded basic applications. Strangely I didn't notice any speed boost while booting and to be honest I feel like all applications (photoshop for example) are also starting much slower than on original hdd.
Is there any way to test hard drive if it performs as it should be? I also have 2 more older drives installed. is it possible that one of them would slow the system down?

My son's 17" imac PPC G5 was not booting up. After a trying a couple of things I got it to boot using Disk Warrior and reparing the file directory. At that time I also ran DW's hardware test which said the drive was fine. My son hard restarted it shortly after I fixed it and it wouldn't start up again. Just a gray screen, no apple logo. When I tried to use DW again it told me there were problems with the hard drive and it couldn't fix the problem. I tried to fix the hard drive in target disk mode using Disk Utiltiy and Drive Genius. No luck. So I pulled a working drive out of my Mac Pro and reformatted it and swapped the internal drive of the iMac with it. There were no DIP switches to set. Started up the imac with a Leopard retail disk thinking I would just install a fresh system onto the replaced internal drive of the iMac. Disk Utility on the leopard disk didn't see the hard drive. Now I'm beginning to think it's a logic board problem but I can't find the original disks to do a Hardware test with. Is there some other way to test a logic board? Or some other idea that I'm not thinking of that could be wrong with the machine?

have a Power Mac G5 1.8 Tower. I get it when they first came out in 2003. Now, This morning I went to log in and the cursor just spins. The system comes on like regular, it shows me the log on screen, the back ground and everything but when I put in my password nothing happens. The pointing cursor just spins and it does not leave this screen. I don't think it is a Hard Drive problem because then I would not even be able to get to this screen, I been trying this for hours now. I even tried to do the Hard Ware test but the CD tray wont come out.

After installing OS X Lion on my Imac (middle 2007)
start up is very slow. Screen stays white with grey progress bar very slow to complete.
Then, after maybe 15 minutes, the desk screen appears and the Imac seems to work normally. I had upgraded the RAM to 3 Go before installing OS X Lion.

I have added all of the updates and patches but the problem continues. It started with one application and now it's happening to others where they shut down suddenly at start-up and have to be restared and the windows restored. It's a brand new computer and wasn't doing this initially.

if you recall a thread I started trying to get help on why the Mac Pro was crashing... I finally narrowed it down.After speaking to about 4 different people at apple.... they had me run the Apple Hardware Test off the boot CD.I took out EVERYTHING except the 2nd DVD burner (Apple Branded Superdrive from my old 2.5 Dual G5)... and ran the test.The Hardware Test ACTUALLY FROZE IN THE MIDDLE OF THE RAM TEST.I thought I had bad aftermarket ram... as it wasn't playing nice with the Apple ram when I added them together.Looks like I had fine aftermarket ram... the Apple ram was bad.I REPLACED the Apple Ram with the Aftermarket Ram... and the Hardware Test completed fine.So, now I'm going to be calling them again in the morning and letting them know what happened. I wonder if they'll just let me RMA the bad ram, or if I'm going to have to lug this dang thing down to an apple store.I WONT BE HAPPY IF I HAVE TO DO THAT.Oh, and no more lockups since switching out the ram... and all the other quirks (not able to burn CDs in Windows, sloooow Internet page draws, etc...) are all but gone now.

I am running the 27" iMac with dual hard drives and have recently upgraded to Lion. Two things are happening.
1. On cold start / boot up, my system has no sound. And by no sound I mean - no sound. When I go to the Sound option in System Preferences, everything is greyed out and I can not adjust or access any of the controls. The only solution has been to immediately restart my computer. After restart, everything is fine.
2. On cold start / boot up, sometimes I receive a pop up telling me that TestGen is not installed properly and to please re-start. Of course, since I have no sound I'm automatically doing that.
Lastly, and I'm not adding this to the list because there is already a thread about it . . but I will mention it I am getting error messages trying to play certain videos "This video requires Quicktime which is not supported by this version of iTunes."The workaround is that you apparently have to delete the video from your Library -- DO NOT DELETE FILE FROM HARD DRIVE -- and re-add to your Library.

My father who is 91 purchased an iMac in January used it once. He is now just setting it up again after he has recently moved and this will be his only computer… finally getting rid of the PC world of Bill Gates and into a real computer. However, he has forgotten the login password at start-up which was set-up at the Apple Store. Can I reboot the machine with a CD (have one for Snow Leopard) and change administration details this way even though is running OS X Lion?Â

I have got my MBP with 10.6.7 installed now have updated to Lion.Â
So, Whenever I need to run hardware test, i need to insert my CD. Â
Now problem is, I got too many scratches on my CD and it's being tough to carry it all the times. Â
Is it possible to run hardware test without inserting CD and other way around. Â

I have a new mac mini running OS 10.7.2 and I have just noticed problems with keyboard and mouse intermittently not working, along with other random glitches that seem to be hardware related. I tried restarting while holding down the "D" key to run hardware test, but all I get is the computer trying to get onto the Internet to restore. It then asks to choose a network, and when I drop down the menu of network choices, my home network is not listed -- only my neighbor's.  Right after purchase I cloned my OEM system drive over to a faster HDD, and the OEM drive is now an external backup. I wouldn't think that would matter since everything has been working fine for the last 3 months. How can I run a hardware test?

I just bought my 27" iMac. It did not come with any install disks. I have tried everything to reach the Apple Hardware Test. Is it even possible to boot to it with a wireless keyboard? I hate to have to buy a new keyboard just to run one test. I can reach the Recovery HD, but the hardware test isn't there. (I know the computer is brand new, I just want to have the info when I will need it someday.) Â

My early 2008 24" has suddenly developed a problem - screen has gone black (initially it was 'black' with backlight on, now not even a backlight) The machine has Lion installed but it came with 10.5.2. I can access the machine via screen sharing & it all runs fine so I want to determine what is wrong with it. I dropped in my original grey system discs, pressed 'D' on start-up, nothing. It seems Lion no longer supports Hardware Test from discs on older machines. How I can run hardware test on this machine?

My iMac does not start up as usual. I now get a ' start up disk is full. You need to make space available on your start up disk by deleting files' message. Â I am able to key my log on password however I just get the purple galaxy screen with no desktop.Â
If I try to use the keyboard I get a tone when pressing the keys. Â
Has worked perfectly well up until I got this dusk full message. Â

Every month I execute Apple hardware test. The last time the following error was given:
4MOT/4/40000003:HD-1258
Apple support could not tell me what this error means. The support technician told me that some error messages are harmless.

I have a 17" unibody MBP (early 2009, specs below). It was running hotter than usual the other day, so I F2 booted into AHT to run a diagnostic. The status box within AHT showed 1 second into the 1st pass, and never got beyond that. Several seconds after that status message was displayed, the cursor froze. The time counter never advanced after that, and although I waited a long time, nothing happened. The test froze.Â
I've tried it several times more. It once worked, but every other time has frozen. Checking the "extended test" box, or trying to run in loop mode has made no difference - still freezes at "1 second".Â
I've had this machine for 3 years, OS's Leopard through Lion, and this has never happened before. I last ran a test, successfully, in January. I've not changed any components or suffered any damage since then. Memtest (ver 4.22) says my RAM is fine. (I ran this because the first portion of the AHT is the RAM component.) Aside from the aforementioned overheating episode, which disappeared, my machine's been fine.Â

Our 2011 iMac with SSD takes 2:15 (two minutes and fifteen seconds) to start up. Start up on a SSD should be faster. OS X version 10.7.4 and applications are on the SSD. Any suggestions for correcting this lack of speedy start up?

What means hardware test fault 4Mot/4/40000003:HDD-1255? I´m searching for the reason of frequent freezing and finder freezing, freezing in Safari too, and got this result with extended Apple hardware test from CD. Checking volume by Lion recovery tells: volume seems to be o.k.

After connecting the imac to a new router the system hung completely up. After each input, e.g. opening preview or a browser, the coloured turning disc appeared and nothing happened anymore. Several restarts, also in safe mode, were unsuccessful. I could not switch to another user. Restart is only possible at all from installation disc but thereafter problem remains the same.
