Hardware :: EMac Aborting Apple Hardware Test (Memory Leaks)
Dec 17, 2009
I do pro bono tech support for a local elementary school computer lab filled with 20 G3 iMacs and 4 eMacs. One of the eMacs recently began throwing intermittent kernel panics. Specs: 1 GHz, USB 2.0, single 512 MB PC2700 stick. mfgd. March 2005. DiskWarrior 3.0.3 found no problems. Repaired permissions and ran Disk Utility repair. Open Firmware resets were done (set-defaults, reset-nvram, reset-all). Problem still existed. Then I booted from the Apple Hardware Test disk. It passed the Quick test, but the Extended test was aborted during the Memory test. There was no error code. Instead, an Open Firmware window popped up. It said AHT was aborting due to a script execution error in AHT on line 11688. Underneath this was a line that said there were memory leaks.
AHT was rerun, and both Quick and Extended tests were aborted with the same message. The 512 RAM stick was removed from slot 2 and placed in slot 1. Cuda button was pushed. AHT was rerun and the same aborting script execution message happened on both Quick and Extended. The 512 MB RAM stick was removed and two known-good 256 MB sticks were placed in the slots. Cuda button was pushed. AHT was rerun and both tests were aborted during the memory test portion. The only difference is that the error occurred on Line 11685 both times. The locations of memory leaks changed too but I didn't write those down. This AHT is Stand Alone Diagnostics V23.0. Is that the logic board's memory controller is failing.
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.
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".
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.

I read somewhere that memtest can be used to test the memory of your mac. I tried it and it didn't even know what memtest was. Is there a way to test the memory in the unix shell?
I've kept my Mac on for days in order to test out these memory leaks that Safari, iTunes, etc supposedly have.
Safari is now using 1.01 GB of memory. And that's not from having 100 windows open or anything. I usulaly have a few windows open with a few tabs each most of the time. But it's just the size to which Safari has grown. It started out much less. Under 100mb I think.
iTunes is up to 280mb from 50mb and I believe it was even higher earlier in the day somewhere in the 330mb range.
I have 4 gigs of RAm on my aluminum iMac, but now I have only 58mb of free memory left!!!
When memory runs out what will be the result? Is Safari just using a gig of memory because it can??? Will this slowdown my system? Or will Safari and/or iTunes give up memory starting with the oldest data first? Am I reinventing the wheel here? What will this test or observation prove?
I have had a look at previous Q & A and am satisfied that 1.5 GB ram is fine in the eMac however i would like to know what the symptoms would be if there was memory incompatibility.
There is a long story , here is the short version.... Basically things went into a frenzy, wouldn't even shut down. The (additional) memory wasn't put in at my place and the computer also had updates done by the other person, when it came back it was unbelievable.. and worrying... my son refitted the 2 sticks that were in it, still frenzy, thought it was wrecked, looked up book, did safe boot. after angonising minutes everything came back.
Gathered courage and we re installed the (new) 1gb alongside incumbent 512 and now things seem ok.
I don't believe the ram is /was faulty so something else went on.
The sticks that are in the machine are 512gb DDR SDRam PC3200U 30440 ( this was one of a matched pair)
1 gb DDR SDRam PC 3200U 30330 ( this is the new one)
I felt i bought the 1gb carefully to be compatible. I do see there is a difference in the last number.

What is the minimal configuration (operating system and memory) for installing iTunes 10.x on a G4 eMac?It already runs on Tiger 10.4.11 with 718MB of RAM.
I have a busted DVD drive, and I need to run the AHT utility. I heard it was in the /system/Library/CoreServices/ folder. It's not for me. And so, pressing "d" or "f2" on a reboot doesn't work. Anything I can do to run AHT without getting my DVD drive repaired first?
I'm running an extended Apple Hardware Test on my 4Gb MacBook Pro. It's been running 50 minutes and isn't even 25% completed going by the progress bar. It's been on the same step (memory pass number 2) for pretty much this entire time. Is this a sign that something is wrong with my MacBook Pro? It was purchased new in June of this year.
I am receiving a G5 Power Mac and I will need to run the Apple Hardware Test to check it. It has no install disks. Does anyone know where I can obtain the Hardware Test to check the computer? I do have a Mac Mini install disk for my Intel Mac Mini, will that Hardware test work with the G5?
I purchased my Macbook Pro (Early 2011) 2ghz i7 edition, about 4 months ago now,
Earlier today my MacBook Pro ran a grey bar update during start up started up & ran a little slower until I restarted afterwards. I was concerened until the restart, however I am no longer concerned. My main issue is that now I can't seem to correctly follow the instructions to successfully start an apple hardware test. I have previously owned a Mac mini, Powermac G5 Dual 1.8ghz and Powermac Quad G5 and I have always been able to successfully run apple hardware tests on them.
I held down the "D" key during startup prior to the grey screen and I tried plugging in a ethernet cable, the powercable and a USB keyboard all to no avail.
I've been having issues with my 2011 MacBook Pro, I just keep getting a weird error popup but it always flashes up and goes away before I can read it. My Mac has also even running a bit slower lately and I know that I can do the Apple Hardware Test to check out that all the hardware is functioning properly. But will my Mac continue to run normally after I do the AHT? Like, will I be able to use it as I was before?
After a lot of erratic behavior with my dual 2ghz g5, I ran the apple hardware test. When testing RAM it gives me the following error message each time I run the extended test:
2MEM/1/4:DIMMI/J11
I'm wondering how to interpret this exactly which RAM is bad (more specifically where is it?) I'm wondering if there is a diagram out there so I can relate this an exact location on my computer.
The next security and maintenance release for Apple's Leopard operating system could arrive sooner than later if the company maintains its current cadence, which has seen two successive pre-release builds land in the hands of developers in just five days. On the heels of the first external test build labeled Mac OS X 10.5.3 build 9D10 and released privately late last week, the Mac maker on Tuesday followed up with build 9D11, which adds nearly 20 more fixes and code corrections, bringing the new total expected with software's release to nearly 100. Among the most recent improvements, according to people familiar with the ongoing testing process, are fixes to AirPort connection issues and problems with the MacBook Air's sleep functionality. Other fresh fixes target Time Machine, Spaces layering and preferences, graphics corruption, display issues within Mail.app, Back to My Mac communication issues, and Automator quirks when interacting with Mail.app.
As was the case with Friday's pre-release distribution, Apple reportedly asked that its developer community focus their ongoing testing efforts on two dozen core system components. These include, but are not limited to, AirPort, AppleScript, Audio, Dashboard, Directory Services, Dock, DVD Player, Finder, Graphics, Installer, Printing, and VoiceOver. Mac OS X 10.5.3 Update, which currently weighs in at a hefty 410+ MB in Delta form and 530+ MB in Combo form, will mark the third update to Mac OS X 10.5 Leopard since the software made its official debut in late October. While those people familiar with the ongoing testing process have been unable to provide a target release date, it's presume the update is being groomed for distribution sometime in April or May.

I'm wondering if anyone has any information on the network boot Apple hardware test done in the stores - how it might compare to the OS9-looking hardware test that comes with the machines, or would have been used over USB if an Apple tech were working on it. The network version looks radically different from either the CD that shipped with my machine, or the ASD CD.
II'm running the AHT on a 2012 quad core i5 iMac 16gb/3TB the progress bar moved quickly to about 7/8 done, about 4 minutes, but now has been sitting there for 40 minutes.
I have a MacBook Pro (17-inch, Late 2011) using OSX 10.7.5
Trying to run Apple hardware test as my computer keeps crashing, or shutting down 30min in. I restart while holding down "D" and nothing comes up. takes a while to startup, but then goes straight to desktop. What am I doing wrong? I'm ethernet connected to internet. When I bought the computer I installed an SSD HD. I remember when needing to install new software on the new drive it was a nuisance since the computer didn't actually ship with any software CDs. Had to do it over the internet somehow. The computer didn't have any problems before so never had to use AHT until now.
secondary question. I also reset SMC, by pressing left side shift+control+option+power key after shut down, but didn't get much response out of that either. no sound, or signal that what I did actually reset SMC. How would I know it reset or not?

Apple on Tuesday afternoon pushed out another private beta of Mac OS X 10.6.3, asking its developer community to test font compatibility and stability alongside a handful of other components that have been in need of evaluation for the past several weeks.
Those other components include iCal, QuickTime and graphics drivers, according to people familiar with the beta software. The last private beta, distributed March 5th and labeled build 10D567, also listed those components as focus areas, in addition to Rosetta and third party printer drivers.
When it's released later this month, Mac OS X 10.6.3 will bundle an update to QuickTime X that improves security and compatibility while also enhancing overall reliability of the media software.
The Snow Leopard update will also include tweaks that enhance the performance of Apple's 64-bit Logic pro audio suite and deliver better compatibility with third-party printers and OpenGL-grounded applications.
Other fixes baked into the release target issues with mail messages displaying the incorrect background color and problems copying files to a shared Windows volume.
The latest beta carries build number 10D571 and weighs in around 700MB.[ View this article at AppleInsider.com ]
1.) Download Image from [URL] 2.) Save it to computer and then open it up in Photoshop 3.) From there please apply a 'radial blur' with the settings at:
Amount = 100 Blur Method = Spin Quality = Best
Using a stop watch / ps timer see how long it takes to apply this filter. I just want to see what mac systems can do, be it a powermac dual 2.7 or an older dual 1.8 or even an ibook. Please list your mac system, cpu details, amount of ram and the time it took for the test, just so we can get an idea of how different mac machines handle this task.
My wifes new macbook has had a few weird things happen, including 2 kernel panics right out of the box. She puts in the restore discs, reboots holding D and gets to the AHT screen. Selects the language then gets the that message, "apple hardware test does not support this machine"
is it possible to use the Apple Hardware Test if I have a firmware password?
I know firmware password stops you from using the "c" or "d" during the boot, and I haven't seen any alternate way to start the Hardware Test (I managed to use the Disk Utility by booting to the DVD, but there wasn't an option for the hardware test that I found there).
suddenly, everytime i start up my computer, apart from the apple icon, now there also is a symbol for the apple hardware test as an option when the comp starts up!
anyone who knows how to erase this so that when i start my comp only the apple logo appears when it starts up with the light blue screen?
I'm running one on my mid-2009 15" MacBook Pro with 4Gb RAM. It appears to be taking forever as it tests memory. It's been on Pass Number 2 for around 30 minutes now. The progress bar is either completely stalled or moving VERY slowly. Is this normal for the extended AHT? This is the first time I've run the extended test. I ran the quick test just prior to this one and it returned no errors.
Is it possible that a failing I/O board would not show up as a problem in Apple's hardware diagnostic test? (from disc 1 of those included with the computer). I'm specifically referring to the Left I/O board, which handles the left ports, the a/c adapter, and part of the wireless connection. My battery just fried and now my airport card isn't working, and after trying everything, I think I may have found the issue.
I cant start my MacMini 2,1. I get some kind of panic error when I start and it constantly tells me to restart. I have managed to perform the Apple Hardware Test. Each time a new error is detected.
4MEM/1/40000000:001301d4 4MEM/1/40000000:00554194 4MEM/1/40000000:001681d4 4MEM/1/40000000:017301d4 etc.
I have a Mac Mini 1.83 Intel Core 2 Duo 1 GB ram. My internal drive is shot and I need to run the hardware test that came with the system (on my leopard disk) from an external optical drive. I am now running snow leopard 10.6.8
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.)
I have an iMac intel core 2 duo late 2006. I have upgraded it to snow leopard. From two months ago, it began to show distorted pictures, random lines/pixels/, and regular freezing. But if I boot it into the safe mode, it works well, although there is no sound or webcam. I did a research online and it seems that I should run apple hardware test (AHT) first. But the DVDs came with this machines have been lost. where can I download this software?
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.
