Won't boot from Apple Hardware Test or 10.1 Install disc

Disk utility states that I need to boot from a CD and then run Disk Utility to repair my disk. However, neither CD seems to be recognized as a viable startup disk from either holding down the C key or trying to select it as a startup disk in System Prefs.
FYI, I am running 10.6 and trying to boot from a 10.1 disc and an Apple HT disc with SW version 1.2

There is no way any Intel Mac will run with 10.1 -- it was released before there was any Intel support in the OS.
Every Mac model requires a specific version of the Apple Hardware Test to support its hardware. (If yours is the "Late 2008" black MacBook, the Mactracker database says it requires version 3A147.) Somewhere in the fine print of your original grey system disc set, or on any other grey system disc for any model, you will find the version of AHT it contains, if it contains any version. Unless that version is the same as your Mac requires, it won't work.

Won't Boot to Apple Hardware Test or accept Boot Commands

Hi All,
I would appreciate some help with this issue, I am trying to boot up to the Apple Hardware Test on my Install Disk 1 that shipped with my MacBook Pro 2.4GHz Model #A1226 ordered new with 4 gigs of memory (around Aug. 2007). I am currently running 10.5.6 and the install disk of course contains the Tiger OS. I have nothing plugging into my computer, other than the Power Adapter. I have the proper install disk inserted in the computer and am holding down the "d" key on my built in keyboard throughout startup, but it will not go to the AHT. It simply boots to the normal login screen for Leopard. In fact the only boot commands that I see any visible or audible confirmation that it has taken effect is the option key, taking me to selecting a Startup Manager and holding down the Power Button gives me a tone from the internal speaker after a few seconds.
Below are what I have tried with seemingly no effect:
"d"
"c"
"t"
Option-Command-"p"-"r" (no beeps)
Command-"v"
Command-"s"
Shift (not sure I should see or hear any confirmation, I don't have any login items set right now so I can't tell if it has any effect)
I have not tried an of the networked drive boot commands as I don't have any networked drives
The only way I have been able to boot from either the optical drive or another disk is either holding down the option key during boot up or selecting the drive from the startup manager in system preferences.
I can't seem to access the AHT an in any way. The reason I am trying to access it is because I have had a few weird intermittent problems that I can't put my finger on and would like to be able to rule hardware out.
I also just replaced my HD with a WD 320 gig drive after my original drive failed due to a physical error. I just restored my data, and all seems to be running well after a permissions repair and a disk repair while booted up on my install disk.
The intermittent problems I was talking about are very vague and rare so I is difficult to describe them other that just a hunch that something is still a bit off. One is the display, every once in a while, showing what looks like a massive bar code or UPC code on my screen. This is not like the bands with soft edges that seem to be a well documented issue with the early MBP but transparent lines of alternating width and brightness with hard edges. Again it looks just like a UPC code transposed on my screen. The other items are random freezing of the OS or the mouse and the fact that my keyboard does not respond to any but a few boot commands. Again all the things are either rare and intermittent or do not come up in daily use of my machine. But when taken together, seem to add up to the conclusion there is still some issue present (at least in my mind).
To recap my specific questions relate to not being able to run the Apple Hardware Test and many of the boot commands having no effect. If you can shed light on the other items mentioned, great!
Thank you!

At a guess, I would think this error code has to do with the video artifacts you are experiencing. You might try reseating all the cables to the display. If the position of the screen makes a difference, there may be damage to a cable, particularly where it goes through the hinge.
Apple is the keeper of the error codes. If you have access to an Apple Store, you could probably ask about this.
Don't know about the other intermittent problems. Does an external keyboard work? If so, there's likely a problem with the internal, maybe even again, a cable or connection.
You could also try creating a new use account and see if the keyboard and mouse problems persist. If not, there could be some sort of software corruption in your usual account. Ditto with the freezing.
Good luck!

Error when booting from Apple Hardware Test (AHT) CD

Just downloaded AHT 1.2.6 from here for my 2nd-hand Power Mac.
Burned it to CD with Disk Utility on my iBook, booted from it on the Power Mac, and received the following message after the "loading..." splash screen:
invalid memory access at %SRR0: 00034870 %SRR1: 00003030
This left me at a command prompt, from which I chose to shut down the Mac.
My Mac version is PowerMac3,6 4.4.7f1. Is this error down to using an incorrect AHT CD, or something fundamentally wrong with my RAM? I did test my RAM after purchase with Rember and possibly also with Tech Tool Pro 4.5.3 - no errors reported then.
SiR G.
EDIT: The Power Mac now has its original graphics card installed, not the ATI Radeon 9800 Pro; however, it still has the Sonnet card in place as the boot disk runs from this.

Hi,
You have the same problem as I, but I also noticed your firmware is a little off. The absolute last firmware update should have given you: "4.4.8f2". Here, have a look at mine.
Machine Name: Power Mac G4
Machine Model: PowerMac3,6

Yeah, I get the same problem as well with the AHT CD, strange as it seems. I tried removing DDR chips one at a time to find the culprit. It seems that I have been unable to figure out why it goes to the open firmware command line and prints: invalid memory access at %SRR0:00034870 %SRR1: 00003030. I ran memtestosx with applejack and although it took hours for it to complete, it gave me fantastic reports of all my memory functioning normally. I do notice the following with my memory:

Apple Hardware Test : Use original Tiger Instal disc, or new Leopard disc?

Hi,
I'm STILL trouble shooting my slow iMac. I figure this may point me in the general right direction.
My question is if my computer came with Tiger, and Leopard is now installed, which startup disc should I use?
thanks

Hi:
Try the OS X 10.5 DVD (boot while holding down the "D" key). I have, frankly, never tried to run an "old" hardware test on a "new" computer, but nothing should be harmed by trying.
Incidentally, slow is usually software-related not hardware-related.

Can't boot off Apple Hardware Test disk

Can anyone suggest why my laptop won't boot off of its Apple Hardware Test disk anymore? I have not tried it in years, but want to try now. I have the original, and a copy I made years ago, and neither will boot. I can select them at startup disks in that preference pane in OSX, but then it fails to find it, and boots into OSX. I can boot into OS9 on the hard drive. I was able to partially boot off of a different AHT disk from my 12" Albook G4, but it gave the message that I can't use that disk since it is not meant for the Tibook. One idea is that TechTool tells me that "macintosh startup file was absent", and the Help file states:
"The Startup file is intended for use by systems that do not have built-in ROM support for booting from HFS Extended volumes. The first eight extents of the Startup File are stored in the Volume Header. This makes them easy to locate and read into memory. This file contains information used by the computer’s ROM to determine what program will boot the computer. In almost every case, this will be configured to point to the preferred System."
But it does not tell me how to restore this Startup file.
-how can i get my startup file back?
-my computer boots fine off the hard drive, so is this file used only to boot off a CD?
-any ideas why i can't boot off my AHT CD?

Hi, t. (That alias of yours sure is a mouthful.) I think in your shoes I would pose the question to the tech support people at Micromat (TechTool's developer). It's their error message, after all, and they should be able to explain it to you in as much detail as you need. Perhaps they'll shed some light on the original problem in the process.

COOL FEATURE-Apple Hardware Test built-in. No disc needed!

It's a MacBook Late 2007... it would be interesting to see what other models have this feature.
Start the Mac
hold the D key
do NOT put in your installer disc
it starts up Apple Hardware Test (AHT) in like 5 seconds. No disc needed. VERY COOL
(unfortunately, it seems to have been disabled after I did the Keyboard Firmware Update) -- 2 units, same issue.
Is there a way to get this feature working again?
What other models have (had) this feature?

Well, I've tried some experiments:
1) Removed the hard disk from the MacBook, and tried starting up while holding down the D key. Question mark icon. So apparently the AHT is not in ROM, but ensconced somewhere invisibly on the HD.
2) Put the HD back in, started the MacBook from a standard, late-2007 retail 10.5.1 Install DVD (not the Install/Restore DVD that came with it). No AHT of course. And when it started up, the backlight went dark. Shining a lamp on the screen and looking from an angle, I was able to see enough to erase the HD. And tried starting again with the D pressed. Question mark icon. So apparently the AHT is not in a special HD partition that persists even when the HD is erased.
3) Installed 10.5.1 on the MacBook HD using the standard 10.5 Install DVD (not the Install/Restore DVD that came with it); once again, running the MacBook from that DVD turned the display backlight off. Then started the MacBook with the D key pressed. Question mark icon. So the standard, retail 10.5 Installer doesn't install the AHT.
4) Started the MacBook from its own Install/Restore DVD, and restored the factory HD setup. When setup was finished, shut down and started again pressing the D key. Apple Hardware Test (v.3A143) appeared.
Conclusion: Apple Hardware Test is on the hard disk, not in ROM, installed as part of the software specific to this model. If the disk is erased and System software is installed from a generic 10.5 DVD - for instance, because the original Install/Restore DVDs have been lost - AHT will not be installed. So the instructions in the manual apply only so long as the original disk setup (or a restoration of same using the original DVDs) remains. Otherwise the original Install Disc #1 will be required to run Apple Hardware Test.

Won't boot from Apple MacBook Air SuperDrive

I am told to run DISK UTILITY as I get the "No Mountable File System" error for EVERY DMG I try to install. (Install works fine on my 2nd MacAir so the DMG is not damaged.) However DISK UTILITY does not fix this issue.
I am trying to boot to Disk Warrior 4.2 on my Apple MacBook Air SuperDrive. Holding C down for 10 minutes on reboot does not work. Selecting DVD SuperDrive using the REBOOT | OPTION KEY option does not work.
Any ideas?
My thanks!
~P

Sorry, but the current Disk Warrior CD will not boot the recent MacBook Air models. See:
http://www.alsoft.com/DiskWarrior/support.html
The only way to run DW on your system would be to boot the MBA from an external hard drive with your MBA's version of Mac OS X and DW installed on the drive. IF you don't have one available you can use, if there's an Apple Store in your area they may be able to help. Otherwise, you may have to reformat your MBA's hard drive.
Regards.

Message from Apple Hardware Test 4Mot/4/40000003: HDD-1361

Ich habe Probleme mit meiner Festplatte. Nach einem Hard reset kam beim Start ein aktualisierungsbalken. Nach dem der Balken vollständig gefüllt war schaltete sich der Rechner selbständig ab. Ein Start der recovery Partition brachte folgenden Effekt. Im festplattendienstprogramm war die Macintosh Hd. Ausgegraut dargestellt. Die Reparatur lief an und es stand als Meldung, dass keine Fehler gefunden wurden, trotz dem blieb das Programm aktiv. Die Festplatte kann nicht partitioniert oder formatiert werden. Gleiches bei versuchen die Festplatte im Target Modus zu reparieren oder zu formatieren respektive partitioniern. Ich habe nun den Support um Rückruf gebeten. Kann jemand helfen?

The error indicates an issue with the hard drive fan motor. It's possible that you won't be able to recover anything from the hard drive, so if you haven't got a backup, it's difficult to recover files. You can try using DiskWarrior or even taking the hard drive to a company that recovers files, but it's not sure if this will work.
Now, the best you can do is to take your iMac to an Apple Store or reseller to get your hard drive replaced. You can do it yourself, but I prefer not to modify anything on a iMac myself.
Der Fehler zeigt ein Problem mit der Festplatte Lüftermotor. Es ist möglich, dass Sie nicht in der Lage, etwas von der Festplatte wiederherstellen, so dass, wenn Sie nicht haben ein Backup, es schwierig ist, Dateien wiederherzustellen. Sie können versuchen, mit DiskWarrior oder sogar unter die Festplatte mit einer Firma, die Dateien wieder erholt, aber es ist nicht sicher, ob dies funktionieren wird.
Nun ist das Beste, was Sie tun können, um Ihren iMac zu einem Apple Store oder Reseller nehmen, um Ihre Festplatte ersetzt. Sie können es selbst tun, aber ich ziehe nicht, alles auf einem iMac ändern mich

IMac G5 hangs on startup, won't boot from disc

Hello,
My brother's computer has been acting up and I've been unable to fix it for him...so I was hoping I might be able to get some advice here.
Problem: hangs on startup. It goes to the gray screen with the Apple logo and the spinning progress wheel like it normally would, but never gets past that. You can hear the hard drive working and eventually the fan comes on.
What I've done:
1) attempted to boot from OSX disc, same result
2) attempted to boot from Apple hardware test disc. this brings up an open firmware terminal style prompt but does not boot from the disc. using the prompts i reset pram and did the "reset all" command which restarted the computer but it continued to hang
3) opened it up and pulled the only ram chip out and put it in the other slot. Unfortunately we don't have another chip to test out, but if you guys think it is a likely culprit I'll go buy him one to see if that fixes it.
Any advice will be appreciated. Thanks!
-Alan

Do you hear the drive spinning up? Have you tried a safe bootAfter the startup tone, hold down the <shift> key until you (hopefully) reach the desktop, it will be longer than normal, because Disk Utility's "repair" is invisibly run; it also will bypass any login items. If the system gets to the desktop OK this time but stalls when the shift key is NOT held down, the problem may be some login item that will need to be removed, using the Accounts panel of System Preferences and its Login Items section.
You could try to repair the machine using Target Disk Mode to access it.

What Do I Put On the com.apple.Boot.Plist to Make Snow Boot to the Apple Hardware Test By Default?

Hi. My main OS is 10.7.2 Lion but I had installed Snow 10.6.8 into a USB external drive. I will use Snow for apps that run well in it and for the Apple Hardware Test which is was my main reason why I installed Snow. Whenever I boot to this iMac's Snow DVD installers (disc 1 or disc 2) or to the one installed on the external USB drive and press D before the gray screen and 'ding', it doesn't want to go to the Apple Hardware Test. I want ot use AHT because I have no budget for similar apps like TechTool Pro.
Why is pressing the D not working by the way?
Is there a way to edit the Snow's com.apple.boot.plist to always boot to Apple Hardware Test (AHT)? What should I write in it. I'll be using Smultron to edit the plist instead of Terminal.
Thank you in advance.
Gbu.

Put the AHT disc into the machine, restart, holding down the D key. AFAIK, you can't do the way you're envisioning.

MacBook won't boot from disc

On Sunday my ten-month-old MacBook froze up and made some nasty clicking noises. I forced a restart, but now it just boots to a white screen and, after a good five minutes or more, eventually displays the blinking, question-mark folder.
I'm quite certain the drive is toast, but what I find more interesting (and in some ways more irritating) is that I can't for the life of me get it to boot from a DVD. I've tried my Leopard disc and the install disc that came with my computer. I hold C while booting, the drive spins for a bit, and eventually it just spits the disc back out. I've also tried holding D with the original install disc to boot the Apple Hardware Test and get the same result. I've tried holding Option to get a list of boot volumes and just get a white screen with a mouse cursor. I've tried resetting the power management unit and zapping the PRAM, as suggested in the "What to do if your Mac won't boot" list, and have noticed no change.
Thoughts? There must be something else I can do.

You may have a bigger problem than just the Hard Drive. Call Apple support or go by an Apple store if your near one and talk to them. You've done everything you can do. It will be up to them now. Be thankful it's still under warranty.

PB won't boot from drive or disc: HELP!

I can turn the machine on with the power button, and the screen displays the grey background with Apple logo, and the spinning barred circle underneath. The circle just spins and spins. Also, the machine is suddenly very loud--fan or drive making a clattering sound.
I have tried to boot from the Hardware Test disc. I could get to the Open Firmware screen but when I try the "mac-boot" command, I get the following error message: "Invalid memory access." Also, the "eject" command would not open the drive device (though the disc did eject when I powered down).
Also tried to boot from the Software Install disc. I can hear the drive reading the disc, but once the spinning circle comes up nothing else happens.
Now I cannot eject the Software Install disc.
Next steps? All help appreciated!!

Virginia:
Welcome to Apple Discussions.
Let me see if I got this right.
1. You can't boot normally from the internal HDD.
2. You can boot from the Hardware Test disk, but no "Mac-boot"
3. You can't install from the Install Disk.
First try resetting the PRAM (Hit start button while holding down CommandOption+PR) and let it chime at least three times. Then release and see if it boots.
If it won't boot restart and when it gets stuck in the Apple Logo grey screen do a hard reset (hold down the Power button for 10 seconds or so until it goes off) then try restarting.
If you manage to get it to boot Open Disk Utility (Applications>Utilities>Disk Utility) select your HDD and run Repair Disk.
Report back on any progress of lack of it.

MBPro Won't boot from CD

Hello there,
I just brought home a brand new MacBook Pro. This was actually a replacement Apple gave me since my last computer wouldn't work.
When I opened the computer up for the first time and went to set everything up, I chose the option to restore my settings from a backup on my external HD. The backup was from the same OS version as this MacBook (10.5.6), but that Macbook Pro wasn't one of the new ones with the black screen, if that makes any difference.
Everything went smoothly, but once I had restored and started up for the first time I thought I would rather restore from a different backup instead. I went to try and reinstall and the computer won't boot from the CD at all. When the disc is in the machine it can be read, though. Opening the Mac OSX install disc on the desktop and selecting restart from the install menu restarts the machine but it does not go to the install or disk utility screen, instead it starts a continuous restart loop until I hold down the option key and select the HD instead of the disc.
*I have tried the restart from install menu on desktop option.*
*I have tried holding the "option" key during startup and choosing the startup disc*
*I have tried holding "c" when starting up*
*I have tried resetting my PRAM by holding CMND OPTION P R*
This install is working perfectly so far aside from this. However, it worries me that if I do have an actual problem and need to boot from the cd to solve it I won't be able to.
Any ideas?
Thanks!
-Spencer

You might be right about the cd's, except if so that greatly upsets me with the Apple store.
When they took my old laptop that they were replacing (which took a month to begin with), they asked if they could use the box from the new one to send back the old one. I said this was probably alright. The next day though I called and mentioned that they didn't give me the install cd's out of the box, they only gave me the computer and the power cord. They said though that my old cd's should work fine.
The computer that broke was an older MacBook Pro that came with Tiger.
This computer is one of the new generation Macbook Pro's that was supposed to come with Leopard... so, wouldn't they be cheating me somehow by doing that anyways? My Tiger discs definitely don't work, anyways, neither do my Leopard discs for my iMac that I got in September. I even bought Leopard for the old laptop back in September as well, but that disc won't work on this MB Pro either.
I got a little frustrated and tried to see if I could reformat from Single User Mode a few moments ago though, but when I held CMND S on start up I couldn't even enter single user mode... I just got the flashing question mark and folder. Tried to reset NVRAM by holding X as well, and got nothing. Holding Shift on startup resulted in a flashing question mark as well. Very confused.

XServe won't boot from any drive, but recognizes them in OS X Installer

I know I have another post here but this is a different issue, and I've already fixed that one thanks to Camelot .
I just received an 2 used xserves for work. One booted into OS X Server fine, so I scrubbed it and reinstalled without issue.
The second however never booted into an install. That is, I never found it on my network when I started it up and when I pushed the power button it would turn off immediately, suggesting that there was no OS on the disk or that the xserve couldn't find it. I didn't have a spare monitor to plug into it (surprisingly) so I just chalked it up to the fact that it was a new disk and hadn't had OS X Server installed on it.
Now I have a spare monitor, I've gone and installed OS X Server on the xserve. It boots from the DVD just fine, runs through the installer, then when it goes to restart, it won't boot from the hard drive that it just installed OS X Server on, it'll just boot back from the DVD unless I pop it out. If I let it boot up without the DVD in it, I'll get the standard Folder with a ?.
At first I thought it was the drive, so I installed OS X Server on another drive. Still wouldn't boot to that drive, so I booted from the DVD and repaired the disks in Disk Utility. Still nothing. I booted to DVD again and when I went to Startup Disk, it actually did show my disks with their respective OS X Server installs.
When I boot the machine holding alt/option, the system doesn't show my drives, only the DVD if it's in the slot.
I figured ok, this has to be the drives, so I swapped them with those of the identical xserve in the rack below, but my top xserve wouldn't boot from those drives either. Somewhat expectedly however, the bottom xserve would boot the drives that I took out of the first one.
Now I'm just stumped. Any ideas?
PS, drives are unlocked.

I'm running the EFI diagnostic tool now. Firmware and disk I/O path came to mind, let's just hope it's not a major hardware issue

Apple Hardware Test Error IP6M

Hi everyone
I'm only asking this here because I've completely exhausted my google-fu. I bought a used Mac Pro that's still in its warranty, and I'm getting this error from Apple Hardware Test:
4SNS/1/40000001:Ip6M-0.976
I managed to find out that the 4SNS part means it's a logic board sensor error, and that the crucial part is the IP6M bit, which in Service Diagnostic manuals points to:
PP12V_S0 MLB2 240V A Main Current
Honestly, I have no idea what that is.
Googling for this error, I found out this support page
http://support.apple.com/kb/TS4051?viewlocale=en_US
which states that "Although the diagnostic displays the alert that the hardware does not pass for this specific sensor, the computer can be considered as passing."
So, it's apparently a false positive.
This is not enough to convince me that the computer hardware is solid, specially because Apple Hardware Test cannot complete its tasks once it finds this error, so it's possible that there could be more.
I took it to an authorized Apple repair center, and they replaced the video card and a backboard panel (no idea what that is). They told me nothing about this particular error.
Anyone got more info on this? Should I be worried?
Is there any other way in which I can properly test this machine?
Also, in case I need to resell this computer, I'm at the risk of potential buyers refusing the machine due to this error. Anyone knows if updating it to Mountain Lion will fix this false positive?
System Info:
Mac Pro 5,1 - mid 2012
OS X 10.8.2
Quad 3.2
6GB Ram
Radeon 5770

I forgot to mention that even after the computer went through the Apple repair center, the error persists. I don't even know why they replaced parts, because apart from this error the computer was fine.
