OS X Yosemite :: Hardware Test Bypassed During Startup
Dec 10, 2014
I have a mid 2007 20" iMac that I just rebuilt with a new 1 TB hard drive and 4GB of ram. Afterwards I upgraded to Yosemity 10.10.1. Today (3 days latter) it froze up, tried everything but had to hold power button in to shutdown. After restarting I tried doing the hardware test thats in my operator's manual holding the "D" key during power up. It was bypassed and opened straight to my desktop. Can I perform a hardware test with the new operating system?
Info:
iMac, OS X Yosemite (10.10.1), Mid 2007 Intel 20"

After my MaBook Pro2,1 - Intel Core 2 Duo - 2,33 GHz & 2 GB Memory - with 10.6.8. Freeze on startup every time, only running in "Save Boot" mode. I choose do perform a hardware test with the version 3A116 on a earlier Mac OS Install Disk. The test (3 times) shows an error code (after 1. test I switched memory cards), I am not able to interpret this:
4SNS / 1 / 400 000 00 : TBOT

My August 2007 MacBook runs OSX 10.4.10. It has performed flawlessly since my daughter bought it in 2007, and perfectly after I purchased it from her last september. The other night I was surfing the web while flying on a commercial airliner. (GoGoNet or something similar) Performance was kind of slow but I attributed that to the in-air wifi, which I had never used before. Then the browser started to hang with the spinning pinwheel. Option apple escape WOULD NOT force quit safari. After a few shutdowns using only the power button, the mac hung up on startup. I hear the chime, see the apple icon, the gear turns but it never goes past that point. It may be significant that the plane was flying through scary turbulence when my problems began.
When I boot up using the mac install disk 1, I can get it to start cleanly using the C key, the D key and NO keys. But when I run the hardware diagnostic, both short and long test, the mac comes up 100% clean. But i cannot see any test for the hard drive. When I try to run disk utility, the colored pinwheel arrives and it never goes away. When I go down the road of re-installing the system software, I cannot see the target drive.
When I put my ear on the deck, just to the right of the track-pad, I can hear the hard drive quietly spinning away with regular - not random - clicks.
I see that Apple is quietly replacing these hard-drives, but the affected computers seem to have a folder/question mark on the desktop on startup, not the apple/spinning gear.
I really would like to be able to recover my photos and some files if the hard drive is going to be swapped. But I am resigned to the situation that these un-backed-up files will be forever lost.

I bypassed the option to transfer operational data (Libraries, Fonts, etc) when starting up my new iMac and would like to do so now. Drag and drop doesn't give permission to do this post-startup. How can I transfer this nitty-gritty stuff now?

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?

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.

Since I've installed yosemite on my Macbook Pro, when starting up my keyboard doesn't light up. After I type in my password then the keyboard lights up. Prior to yosemite as soon as the area for typing in my password came up my keyboard was lit so I could see the keys in the low morning light just to sign on.

I recently upgraded to Yosemite. Had problems with connecting to the Exchange server so I did a restore from my time machine from the day before I did the upgrade. Now the machine starts to turn on, then shuts down. The iMac does not have a CD drive.

I have a 2010 mac using OSX Yosemite update. It is sticking in the white apple start up screen for a long time. It boots to the password screen, I input password. It then locks up in the password screen. I have a logitech key board. I try holding the shift key at start up for safe mode nothing happens.

I've noticed that when I boot in startup mode, I see 2 different options titled "Macintosh HD":
Disk Utility also shows one "Macintosh HD" partition within "Macintosh HD".
Is this normal, or have I accidentally created a redundant partition?

By the time OS X displays the startup disk full message, you computer is already useless. Is there a way to get this warning at 5GB free space?

I usually connect my iPad as soon as I've heard the startup chimes, but since upgrading to Yosemite, whenever the iPad is connected, iPhoto opens. Usually, nothing will open until all my extension things like Dropbox are happy, but iPhoto somehow manages to kick off. Now, I don't like iPhoto. I don't understand it and it rarely does anything I want it to, so I don't often use it and I particularly do not want it to open, slowing up starting and serving no purpose.Â

I am disabled and unable to type on the keyboard. Can I set my computer not require password at start up? If not, is it safe to just let it sleep when I'm not using it, meaning it would be on 24/7.

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

Recent switcher here. Picked up a G4 17" iMac, and LOVE it.
It could use a RAM upgrade, though. For some reason, the internal RAM isn't being used. The System Profiler claims the spot is empty. The easy to get to one on the bottom seems to be working fine, but it's a lowly little 256.
I'd like to upgrade to its full potential, but am concerned the problem with the internal might be a logic board problem. Any way to tell?
Should I just get a 2gb stick for the known-good slot? Where can I get one for less than the $87.99 Crucial wants for a 512mb?

What's the best way I can test RAM in an old iBook G3? It had a bad module so I replaced it. All seems okay now, but I want to test it to be sure it's all good. Normally I'd just pop in Memtest86+, but Memtest86 doesn't support PPC (obviously).
I don't have any disks for it or anything, so no Apple Hardware Test disk.

I ordered a i7 15" Macbook Pro high resolution anti glare screen over a week ago. I've been reading lots of forums on the subject and have heard about the small print, yellow tint to the bottom half of the screen, the laptop not sleeping etc.
So I contacted the store to find out about the possibility of returning it if I'm not happy. They said I can spend all the time in the store with it but as soon as I leave the store there is a 15% restocking fee. It hasn't arrived yet but I'm expecting it any day now.
Can someone tell me all the tests I can perform in the store before I leave?

I have a MAC OS X 10.4.11 IBook G4 1.1. It's acting up on me. Crashes often and freezes as well. The only CD I can find is the Mac OS X Tiger Install DVD. Is this the Hardware test cd as well? If yes, how do I get the hardware test started. I tried the "restart while holding "C" and "restart while holding the "option key"". Doesn't work. Don't see a hardware test option. If no, Can I download the application?

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?

What is the best was to diagnose possible motherboard faults on a Mac? I'm having various problems which appear to be hardware related (i.e. re-formatting, re-loading OSX, etc don't seem to fix them and the problems appear at different times running different processes) so want to check the motherboard out.Typical problems are a USB hard drive suddening going off-line, the DVD burner suddenly resetting itself for no reason, screen not redrawing properly etc. and all these only happen occasionally. The only test I can find is a RAM test (various programs allow this including Tech Tool Pro 6) but is there a way to test other components?
