Ugh/ kernal panics / apple hardware test will not boot / help

so my first thought is to replace all my memory and I even have some coming via OWC -- but it seems silly just to replace memory on a hunch and randomly. So I run rember and get an all cler on all my memory. Can this really be soo? So I think - try the Apple Hardware Test.
I hold down c key as 'puter is booting and I get command line screen that says
"invalid memory ascess at %srr0:ae0c0108
%srr1: 0c01086F
bad bus info crc-16"
than it tells me to type in mac-boot to boot --but it will not boot - the next screen just says command line ok
what should I do next
this machine has been acting up for over 6 months and its driving me nuts -- I bought the memory as a "quick fix" but now I am starting to have my doubts. It would be cool to know before I decide to install it so I can return it for my $ if my hunch is wrong --
help! and thanks!

I can give you some general advice about buying memory:
The question then becomes what if memtest passes it all... I couldn't complete the cloning of about 220 GB of files from one drive to another with the original MacWarehouse chips in place, but could when they were removed.
I have had quite a bit of experience testing memory, most of it grey market stuff that I salvage from trash cans and such like place. I have found some memory that worked perfectly and never gave me any problems. I have found some memory that gave me kernel panics. I have found some memory that are somewheres in between: they seem fine at first, and then when you start to run lots of apps or copy large files that's when the problems shows up, and the problems are subtle -- once in a while a task would randomly crash, but restarting the task would make it OK, etc., etc.
I've had a PC133 stick that repeatedly tested and passed on memtest until the 4th pass, then an error showed. After the error showed, there were lots of errors.
For my own use, I do not use any memory that fails memtest at all, since I am swimming in memory anyway. I usually test them overnight. Certainly when buying new memory I expect them not to fail memtest when run overnight (usually about 6-7 passes).
I'll use memory that fail occasionally in client stations that are not function critical, but my experience has been once you get some error in a memory chip, it gets worse with time.
I want to avoid if possible having the machine down for hours at a time to run memtest in Single User mode as it's serving up genealogy databases on 4 different domains, as well as static pages on 8 other domains as well as being my every day work-a-Mac.
If you're serious about hosting those domains, I suggest you buy a Mac Mini for your clientstation and let the server be the server.
sending CL3 chips maybe the Apple Hardware Test is expecting to see CL2.5 which is what the 3 chips I have to do work are.
CL3-PC3200 chips can pinch hit for CL2.5-PC2700 chips in some limited circumstances, but they were sending you CL3-PC2700 chips in place of CL2.5-PC2700 chips. I smell herring.
or are they really not the chips the label says they are?
Chips are sometimes mislabeled, due to operator error.

Apple hardware test does not support this machine, iMac 27" mid 2010

Hi, I have a mid 2010 iMac 27inch with OSX Maverics updated to the very latest version.
I need to hardware test my mac but I am finding it impossible. If I press D at bootup, nothing.
Option D, loads hardware test, but it comes back saying:
"Apple hardware test does not support this machine."
I don't have the original install disk for the mac and it has been updated several times online to the latest version. What am I supposed to do in this instance?

That Mac model requires the original system disk to run AHT. You can call Apple at 1-800-MYAPPLE, and ask for an operating system specialist. Then you can request replacement system disks for your computer. The cost us usually under US$20.
Have your serial number at hand; it is required for the techs to find the correct disk set for your model.

Add me to the list of people furious with Apple about this problem...
...I have just got back from a 2 week holiday in Spain, and on day 3 of the holiday my iPhone rebooted itself and stuck at the Apple logo.
What's more annoying, I'd purchased a data abroad plan from o2 for £50 and hardly used it because I couldn't use my iPhone because it was stuck on the **** Apple logo. o2 will not refund the plan I purchased because I had started to use it (about 2.3MB to be precise).
Good job my girlfriend had her trusty Sony Ericsson phone because at least it WORKS as a phone, unlike this **** iPhone 3G which only has one use - as an expensive paperweight.
Come on Apple, at least admit there is a problem and show your loyal customers that you are actually aware there is a serious problem that is causing your iPhones to become utterly useless.
I'm seriously thinking of gettting rid of this iPhone and getting a cheap no frills phone - at least I can use it to make calls.

HT4904 Apple Hardware Test or not?

Tried to open Apple Hardware Test on my MBP Pro 13", but pressing the D-key while starting the MBP did not work.
Turned to "Computers that can be upgraded to use Lion Internet Recovery" where the latest MBP 13" is early 2011.*
My MBP 13" is late 2011 (recently upgraded to OSX 10.8.1).
What can I do to use the test?
*Download and install an updated EFI Firmware ROM for these computers to use the OS X Internet Recovery feature:
MacBook Pro (13-inch, Early 2011)

Ok, I tried it but the disc is damaged and can not be read.
(Strange because the disc have never been used. I called Apple about this and they
said that they do not produce CD/DVDs anymore with AHT.)
Which number did you call?
You can get replacement System Install & Restore CD/DVDs from Apple's Customer Support - in the US, (800) 767-2775 - for a nominal S&H fee. You'll need to have the model and/or serial number of your Mac available.
If you're not in the US, you may need to go through the regional Apple Store that serves your location to find the contact number. Here's a list of links to all of those - http://store.apple.com/Catalog/US/Images/intlstoreroutingpage.html Another resource: International Support Phone #s.

Apple Hardware Test (Extended) not progressing

After upgrading my white MacBook (13-inch, mid 2010) from Snow Leopard to Lion, i was getting Kernel Panics, maximum of 5 min after startup. So i decided to downgrade back to Snow Leopard.
I erased my hard disk, tried to install SL from the DVD that came with the MacBook, i got a Kernel Panic. I tried it for 6 times, all with the same result.
I made the Apple Hardware Test, it passed.
Now i'm trying the Apple Harware Test (Extended), it's been almost 6hrs and here's the status:
Testing Memory
No error messages
Pass Number: 1
Time: stuck on 2hr 15min 49sec
Progress Bar: about 13%
However the mouse is still responsive. Is it normal for the test to take this long.
Thanks
PS: i tried the option-commant P R before running this test, and i dont have any peripheral connected

I have had endless issues with kernel panics since Lion. Rolling back to SL won't save you, because the last couple of updates to SL added in the cause of the panics:
Some combination of multitouch trackpad drivers and the graphics card drivers.
So, what I've done, and it seems to work better ( I can use this POS laptop for more than an hour now) is:
System prefs: turn off all the multouch stuff. All the gestures. Off.
Also, battery life is low because this os constantly writes to the hard drive and uses the network card. If you happen to push the system while you hear the fans spin up as it receives a push notification ...panic.
Spotlight has big problems with Lion. I stopped it from indexing almost everything, installed quicksilver, then turned off indexing on the drive. I uninstall flash unless I need it also.
kernel panics for me would always feature AppleHWSensor in the panic log.
60% triggered by me using the expose show desktop guesture. However, I assigned that to a keystroke... works fine.
I've lost 3 hard drives to this garbage, ( you can't keep on just turning off modern unix systems, via kernel panic)
Try what I suggested:
No Flash until you need it.
Turn off all the multitouch stuff in trackpad prefs
stop spotlight from indexing your logs, and Caches. Then turn it off.

HT201257 Hardware test will not complete

My hardware test runs until its about 9/10 done then it just stays on the progress forever. It never updates the time of testing either. I tired running it of the disk and everything else the help forums told me to do but nothing helped. HELP!

Thanks for the ideas. Apparently some additional context may be helpful.
(1) Yesterday, my Mac Pro booted normally, but soon the monitor went blank. I had to hold down the computer's on button to force the computer to turn off.
(2) In a few minutes, I tried restarting. Still the monitor's screen was black. In fact, the monitor remained in standby mode. Further, when I tried my second monitor, it also remained in standby mode.
(3) Today, however, the computer booted and worked fine. Nonetheless, it seemed reasonable to run a test on the hardware.
(4) Every month, I run both Apple Disc Utility and Disc Warrior on all drives. Further both programs say all four internal drives are fine.
(5) No peripherals are connected other than the monitor, keyboard, and mouse.
(6) Neither my original Leopard OS package nor my original Snow Leopard OS package came with a second optical disc. Neither of the original OS discs will run Apple Hardware Test on restart with the "d" key depressed.
(7) I suppose that if I never can get Apple Hardware Test to run, and I have trouble with video again, I'll try booting from Snow Leopard (my previous OS).
I hope the preceding helps. Thanks again.
Jim

Apple Hardware Test CD not seen

I need to run the Apple Hardware Test but the computer doesn't see the CD when I start using the C key, or even when I use the Startup Disk System Prefs. I have also tried using an external CD/DVD drive & that doesn't work either. In case the AHT disk is faulty I have downloaded & burned a new test disk. Nothing works. Any ideas?

Since this is the aluminum discussion group, I'll assume you meant to post here about your 1.67Ghz Powerbook. First, there is no Apple hardware test that you can download for it, at least from Apple. You need the original OS X disks that came with the system. If you had Applecare, you can download TechTool Deluxe, which does similar testing.
In order to run the Apple hardware test, reboot while holding the alt/option key down, then you can choose the Apple hardware test, or hold the D key down, which should go right to the test. When I run it, I use the alt/option key. If you have the original OS X disks that came with the system, make sure the one you're using says 'AHT Version x.x' in small print on the gray label. If you put the OS X disk in an external drive, using the alt/option key when you boot should allow you to choose it.

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!

IPhone 3G stuck at the Apple logo screen; will not boot!

My iPhone 3G has been working all day. I rebooted it because it was hanging when trying to use some apps, and now it's hung at the Apple logo. It will not boot fully. I have tried to reboot the phone many times but I get the same problem. I let it sit there for 30 minutes and it does nothing.
Anyone else have this problem? Any ideas on how to fix it without doing a Restore?
Ethan

Oh, they know! I've had all of the above issues, tried every and all remedies several times, even uninstalled and reinstalled itunes. My phone froze up totally for over 24 hours after several attempts to sync and itunes closed then I had to reset, not even an apple logo, just a dim lit screen. Went to the genius bar, they replaced my phone. The tech said apple knows and is working on it.
Note: tried to book an appointment online, none available so I went and signed the standby list.
Luckily someone didn't show up, because they said some people wait for hours.
The new one is doing the same thing. I have yet to sync fully. my contacts & calendar sync OK, a few apps, beyond that nothing-no music, photos, podcasts, ringtones. Itunes hangs during syncing an application and iphone times out. the only option is to close itunes and reset the phone. Upon fully reset, maybe 1 or 2 apps are installed, nothing else. Resetting takes forever, it has frozen again with the apple logo for about 12 hours, and usually about 10-30 min each reset. I have restored the new one twice. Problem is, when it freezes up or times out, itunes won't recognize the iphone at all, it says no iphone detected.
I am now going to restore the phone again, and not attempt to install any apps until this issue is resolved. I have already spent hours on this, and really tried everything. I would rather have my music, ringtones, photos, podcasts etc than a few apps. Shame, because i've spend at least $50 in addition to numerous free apps.
Side note: I scheduled another appointment at the genius bar when my phone was out of commission for 12 hours, they are booked for three days in advance so the issue is still widespread. Luckily I was able to finally get itunes to recognize my phone and restore.

10.5.8 Both hard drives OK, tested - will not boot past startup screen

Okay, I have an early 2008 MacPro, and everything has been running fine, but I was trying to search for something in Finder, and it wouldn't show up, so I checked my other hard drive's permission options - it displayed "Custom" for all users, when I know I had them all set to "Read & Write" previously, so i changed my main user's (on my newer HD on 10.5.8) permission to Read & Write on the original HD with 10.6.8, so I could search its contents, then these error messages poppped up, everytime i hit OK, a new one popped up immediately in its place, with some "Apple AUD" OR "HD" messages (can't remember the exact messsages), so I restarted my computer and now I cannot get past the apple logo screen.
- Attempted selecting both hard drives as startup discs and still hangs at the white apple logo screen.
- I tried booting into Safe Mode and it loads the status bar, and when it's done loading, it simply goes back to the spinning gear.
- Tried booting from my 10.5.8 installation disc and it works, both of my HD's tested "OK" when I verified them.
- Tried resetting PRAM, and even reset SMC, and the problem persists.
One last note: the original HD that came with my Mac Pro, which has 10.6.8 on it as of last year, has a tiny lock icon on the left of the little hard drive graphic.
I'm stressed because I use LOGIC a lot, and I have all of my music projects on these hard drives, and over a million files between both of them. I'd pull my hair out, if I hadn't just shaved my head for summer
Any help would be GREATLY appreciated!

Your hard drives may be OK, but the installed systems are not. You need to reinstall OS X on your startup volume. Doing this with Leopard requires your Leopard DVD:
How to Perform an Archive and Install
An Archive and Install will NOT erase your hard drive, but you must have sufficient free space for a second OS X installation which could be from 3-9 GBs depending upon the version of OS X and selected installation options. The free space requirement is over and above normal free space requirements which should be at least 6-10 GBs. Read all the linked references carefully before proceeding.
1. Be sure to use Disk Utility first to repair the disk before performing the Archive and Install.
Repairing the Hard Drive and Permissions
Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger, Leopard or Snow Leopard.) After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer. Now restart normally.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
2. Do not proceed with an Archive and Install if DU reports errors it cannot fix. In that case use Disk Warrior and/or TechTool Pro to repair the hard drive. If neither can repair the drive, then you will have to erase the drive and reinstall from scratch.
3. Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When you reach the screen to select a destination drive click once on the destination drive then click on the Option button. Select the Archive and Install option. You have an option to preserve users and network preferences. Only select this option if you are sure you have no corrupted files in your user accounts. Otherwise leave this option unchecked. Click on the OK button and continue with the OS X Installation.
4. Upon completion of the Archive and Install you will have a Previous System Folder in the root directory. You should retain the PSF until you are sure you do not need to manually transfer any items from the PSF to your newly installed system.
5. After moving any items you want to keep from the PSF you should delete it. You can back it up if you prefer, but you must delete it from the hard drive.
6. You can now download a Combo Updater directly from Apple's download site to update your new system to the desired version as well as install any security or other updates. You can also do this using Software Update.

Ibook will not boot HELP!!!!

Hi,
First the ibook booted then would come up with the kernel error: square box with "you need to restart your computer. Hold down the power button for several seconds or press the restart button......
I then booted to single user mode and ran fsck -y which eventually came up with the all clear "The volume Macintosh HD appears to be OK"
I then restarted the system which booted to the blue screen with some quirky graphics towards the top. It will now not boot into single user mode, just black screen or multi-coloured stripy screen. When booting from the CD drive the sceen is just blue or black.
Has anyone any ideas what this could be

You are having kernel panics as shown in this Apple doc.#106227.

HT1212 screen is blank with the apple logo. Will not boot up after downloading the latest software. Any suggestions?

screen is blank with apple logo after downloading new ios 7. Any suggestions?

Hi, ronia90.
Thank you for visiting Apple Support Communities.
I would first try a reset of the device. To reset a device, press and hold both the Sleep/Wake and Home buttons for at least ten seconds, until the Apple logo appears. You may need to attempt this multiple times.
iOS: Turning off and on (restarting) and resetting
http://support.apple.com/kb/ht1430
If the issue persists, you may need to attempt a restore on the device via forced recovery.

Apple TV 2 Will Not Boot, Flashing LED

Hello everyone,
I was just in the middle of watching a movie and the Apple TV went back out to the main menu, and lost connection with iTunes, I restarted my Apple Tv, and now it displays the iTunes logo with a USB cable on my TV, and the LED on my Apple TV keeps flashing white. I'm guessing my Apple TV want's me to plug it in to my iTunes. I have never needed to plug it in to iTunes before, why now, I have the latest updates.
It's an Apple TV 2 Model: A1378
What's going on?

ah crap, my wife is super mad now lol, I have to go buy another cable, I need a mini USB cable or what ever they are called to plug in to the back of this. That also means I have to rerent the movie we rented tonight *sigh*
Thanks for the reply Eric :O)

Iphone 3g will not boot. help needed!!!

the phone was working and then i tried restoring it when my desktop lost power half way through. it now remains in the connect to itunes state even with trying the hold home and key lock operations. i have tried all the troubleshooting options from apples website with no success.
also i have tried restoring agian but the process is as follows;
1) itunes has detected an iphone in recovery mode, it needs to be restored before use.( after clicking buttons the restore process is started )
2) half way through itunes says it is restoring the software the phone shuts down into recovery mode.
3) itunes pops up a window saying "the iphone could not be restored. an unknown error occurred (14)."
i have been trying to fix this problem for like 23 hours straight as i have just bought the phone. assistance on this would be more than appreciated.

I have had this issue before, the iPhone will hang with the apple logo up indefinitely. I lost patience around 20 minutes. The way I got past this was to hold the power/home button at the same time until the phone powered off, and then retried, repeating around the 7 minute mark until it booted successfully. It has taken 3-4 tries at times, but has always started. This has happened about 3 times now since I upgraded the day it was released.
Also, when it does finally start, I've gotten the "iPhone is activated" popup, and had trouble using apps (closing immediately after splash screen) and certain songs. Seems like it's some sort of DRM credential issue. I downloaded a free app to the phone, and they all began working again, even once the app was deleted. However, if I end up with the boot process stalling and the whole iPhone is activated popup again, I'm back to square one. I also got the songs I couldn't play to play, but I am not sure what specifically it was that fixed that.
I am running 3.1 on a 3G, which I upgraded from the latest 2.x release.

K8T Neo will not boot - Help!

I purchased an AMD64/MSI bundle that refuses to work. I did return the bundle to Komplett but they say it checked out 100% and returned it. Reading threads I can see certain PSU's or RAM could cause problems.
I have detailed the kit below but when I assemble the complete kit and power it on, I hear the HD spin but that’s it. The monitor stays in standby. The 4 lights on MSI “D-Link” are all red & the lights on my keyboard keep flashing. I also tried just connecting absolute minimum items as per FAQ to see if that nailed the problem but is the same result every time. The PSU is a fairly decent Enermax model. The RAM came part of the bundle and works in other machines (anyway Komplett checked it out). The only thing I can think of is that the OS is on a 120GB IDE HD and I also have a 250GB SATA backup drive. This is the 3rd system I have built. Can anyone point me where I could be going wrong as it seems a waste of money with this great bit of kit just sitting in a cardboard box!
KIT:
(forgot PSU) Enermax EG651P 650Watt
AMD 64 3200 Socket 754
MSI K8T Nero-FSR (754K8T800, SATA/ATA, GbLAN)
RAM Crosair Value PC3200 512 (plus 2 more sticks of 256MB)
Maxor ATA 120GB
