New iMac, startup failure, question mark: TH00-9.000 TH0O-9.000

Hi everyone!
My new alu iMac worked for 3 weeks. Today it suddenly crashed. Now the boot process stops with a flashing question mark.
Disk Repair didn't find any harddisks to repair.
System Profiler stated "There was an error while scanning for Serial-ATA devices."
AHT reports the following error code: 4sns/1/40000000: TH00-9.000 harddisk failure.
The error appears during (or after) the main logic board test while the fans spin up.
Looking closely the space between the zeros in TH00 is significantly smaller. So maybe it's not a zero but an upper case O.

Please look over the following Apple Advice letter:
http://support.apple.com/kb/TS1440
My guess is the internal HD has crashed, this of course would be covered by your 1 year warranty so you should contact Apple immediately for repair. Please remember hard drives are not made by Apple and they do fail. Some last weeks some last 10 years, unfortunately they are very unpredictable. While this is frustrating this is why you have a warranty. If you have been using Time Machine then once the internal drive has been replaced restoring will be painless with TM.
If you have added an external HD or have a flash drive inserted in one of the USB slots that can confuse the machine so it doesn't know where the startup volume is. Try re-starting by holding down the Option key, if the machine sees start up disks it will highlight them, then choose the internal HD. Once the machine has started then go to System Preferences-Startup Disk and select the internal disk.
If that doesn't work please post back and let us know what happened. BTW you don't state where you are located but you may be covered by AppleCare. Look in your owners manual for the phone number in your area and contact Apple, you have 90 days of free telephone support.

Why does my imac have a question mark in the doc sayin start osx

my imac has a question mark in my doc. on top of that question mark it say "start osx" how can i fix this

Your images are "disconnected"
that means they are not in the same place on your hard disk as they were when you imported them into Elements. There are a couple ways this can happen, mostly folks who use Windows to move images to a new location instead of Elements will run into this issue.
To fix it, you either need to move them back using Windows, or Reconnect them using Elements.
You didn't mention waht version you have, but it's done the same in all versions.
Here is a link to the Help doc on how to Reconnect.

Reinstalling Lion/Mountain Lion Without Erasing the Drive
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. 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 main menu.
Reinstall Lion/Mountain Lion: Select Reinstall Lion/Mountain Lion and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.

New hard drive blinking question mark in a folder

I have an iMac G51058 the hard drive is dead, so I changed for a new one. I turn the computer on, insert a 10.5 disk turn off, wait 30seconds and turn on pressing the option key. A folder with alternating Apple face and a question mark blinks forever. Any suggestions?

power off machine. Hold down the option key. Power on machine. continue holding down option key until you see the startup manager screen.
sometimes you need a wired keyboard for this to work.
Sometimes if volumes don't appear in Startup Manager (what you get when you hold down the Option key at startup), you need to reset the Mac's PRAM, NVRAM, and Open Firmware. Shut down the Mac, then power it up, and before the screen lights up, quickly hold down the Command, Option, P, and R keys, until the Mac has chimed twice more after the powerup chime.
Then, before the screen lights up, hold down Command-Option-O-F until the Open Firmware screen appears. Then enter these lines, pressing Return after each one:
reset-nvram
set-defaults
reset-all
"The reset-all command should restart your Mac. If so, you have successfully reset the Open Firmware settings."

Macbook Air won't startup, flashing question mark

Hello everyone, here's the problem:
Recently (Sep) I've bought a new macbook air (2012, 128gb SSD). After a few months of using it the following problem happened: while surfing on the web, my macbook hang up (I couldn't press anything or do anything, the system wouldn't respond), so I shut it down forcefully (by holding the power button), after this my computer wouldn't boot at all: a flashing questioning mark appeared on the grey screen. I know what it means (I'm an Intel engineer and know quite a bit on the subject), so I thought the SSD was dead. Brought it to the shop a bought it at (M-video, Russia, Nizhni Novgorod). After 21 day (sic!) they gave it back to me working fine and said that when they opened it - it worked OK, they tested it for 5 days with reboots and it was OK. After 1 month of using it after I got it back (today) it happened again: the OSx hang -> force shutdown -> question mark on startup.
Could you please tell what can it be? It's obvious that it's no a hardware problem (in this case it wouldn't happen from time to time but be a permanent defect after the first time it occurred). I tried all the recipes found on the internet (command + alt + P + R; R to get recovery mode - disk utility sees only 1 partition on disk0 of 1.8 GB (I guess it's partition with the base system) and won't let me do anything - all options are grayed out; SHIFT won't let me into safe mode - no idea why; etc.). I also don't have a CD or anything with the mac OS, however even Internet recovery won't help - no targets to install it when it comes to it.
Have tried almost anything and asked almost anyone among my IT-connected friends, but in vain. Thank you in advance for your help! Will appreciate any piece of advice.

Install or Reinstall Lion/Mountain Lion from Scratch
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Erase the hard drive:
1. Select Disk Utility from the main menu and click on the Continue button.
2. After DU loads select your startup volume (usually Macintosh HD) from the
      left side list. Click on the Erase tab in the DU main window.
3. Set the format type to Mac OS Extended (Journaled.) Optionally, click on
        the Security button and set the Zero Data option to one-pass. Click on
      the Erase button and wait until the process has completed.
4. Quit DU and return to the main menu.
Reinstall Lion: Select Reinstall Lion/Mountain Lion and click on the Install button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible
            because it is three times faster than wireless.
If this fails then see: OS X (Lion/Mountain Lion)- About OS X Recovery.

Frequent startup with question mark folder icon--a diagnostic challange!!!

I recently obtained a 500 mhz G4 Cube; I transplanted memory, video board, video riser board, and DVD/CD drive from my old (dead) 450mhz G4 Cube (logicboard and DC-DC board were fried) to the 500 mhz Cube AND I added a Western Digital 80gb hard drive. The problem involves frequent startups with the question mark folder (Mac OS logo alternates with question mark).; Eventually the system folder is found and OS 10.4.11 starts up--sometimes in 20 seconds and sometimes in 3, 4, 5 minutes or longer..........I have tried 2 brand new batteries after numerous PRAM (via keyboard) and CUDA resets (depressing the CUDA button on the motherboard just once and then installing the new battery). The battery terminals in the Cube look perfect--no corrosion. With the new battery, startups were fine for a day but now 4 out of 5 times, I will get the question mark folder. Using Disc Utility, I fixed any errant permissions and the hard drive checks out with zero problems. Once running, the Cube works great, but these startups are maddening. One other issue; if I start up with the G4 Cube 9.1 installation disc, the install program DOES NOT recognize any bootable discs; whilst starting up using the Tiger Upgrade install disc, my 2 bootable discs (partitions of my Western Dig. hard drive) ARE recognized. Any ideas would be greatly welcome!!

I believe I have solved the problem regarding the question mark startup---> after rechecking all cable connections to HD, OD, and logic board, I revisited the jumper setup on the HD; it turns out that I set the HD up to be the MASTER, but what I should have done was set the HD to be the MASTER with attached SLAVE. Since reconfiguring the jumper, all startups have so far been normal. Also, I did install OS 9 drivers, but I the OS 9.1 install disc still does not recognized my 5 gig partition when starting up from the CD; this is minor in retrospect as I can still use the classic mode with a earlier version of OSX that does not hog so much disc space.

Just got a new mac pro - flashing question mark and more...

I wonder if anyone can help me solve this problem. i just bought a mac pro, turned it on and a flashing question mark blinked on the screen. i got on my mac book to search apple.com for the problem and it said to boot with the install disk and hold the c key. i did all that and now i cannot take out the disk. i'm still unable to select a startup disk either. i currently have a mac g5 and loved it but it is old am really surprised with having this problem. can anyone help?

If it's new and it does that, it's very likely a loose component. If you feel comfortable doing so, open the case, and make sure that the RAM is firmly seated in its sockets and the drive cables firmly connected to the drives and the circuit board. Also check the power cables to the drives.
Depending on how the computer was handled in transit, these things can get jostled loose, and loose RAM or cabling will give you what you observe.
The other possibility is an outright hardware fault. Though rare, there's always hardware that resides in the tail of the service-life bell-curve due to some manufacturing / material defect. Apple is historically excellent about replacing same. You need to contact AppleCare or bring the unit to an Apple store or authorized repair center.

Imac displays flashing question mark and nothing works

Hey everyone, my just the other day i turned off my imac (when it still was working normally) and the day after i turned it back on but all it does is showing me a flashing question mark!
This is what i've tried so far to fix this:
- Hold down option at startup with a snow leopard retail disk in it, nothing appears except the mouse cursor.
- hold down c at startup, nothing happens
- Reset NVRAM
- Hold t at startup, nothing happens
- Hold shift at startup, nothing happens
- Hold command-v at startup, nothing happens
- Hold command-s at startup, nothing happens
How can i fix this?? please help me because i'm going crazy!
Greetz, rutger

Hi, a few days ago I had the same flashing question mark. I had just emptied my trash in iPhoto for the first time, (a few thousand pics), and was browsing in the main photo library when suddenly everything just froze. I left it for awhile, came back and nothing had changed. I switched off using the power button, and when switching on again, the flashing question mark appeared. None of my attempts to reboot worked as it appeared there was no drive to be found.
I have to add that iPhoto would often just quit for apparently no reason, and unexpectedly, having 'encountered a problem'.
I have now been told that my HD is dead, (my iMac only 8 months old), and that i wont be able to retrieve any data (20000 photos that stupidly I hadnt backed up!)
I had too much faith in this product, having only recently converted from Windows, (which was always backed up!), and now feel very disapointed and let down....... this has been a very costly lesson,and one I wont repeat!!
good luck, and I hope you are backed up!

Startup Disk Question Mark

I have a weird problem. Well I guess its not really a problem. I reinstalled a new hard drive into my Macbook Pro and I installed everything and everything works beautifully. However I noticed that in the preference panel that there is a question mark on the startup icon.
http://img258.imageshack.us/img258/4059/picture1dm7.png
When I reboot I see NO folder with a question mark or anything of that sort. I had tried to select the hard drive as a start up disk and restarted but the icon does not change. I do NOT have boot camp for it is a fresh install.
Is this a visual glitch or can something be done about it?

Its always been like that? Weird. I've had leopard for over 6 months now and I could have sworn that it never had a question mark. O well. So then everything is normal!! Great!
I guess the thread may be closed now.

New iMac, have several questions

Community,
First of all I'm not sure if this is the right community to post to. My questions seem to span several forum categories. If there is a better general forum for my questions, please let me know.
I just got a new iMac, (21.5 inch late 2013), with a 1T fusion drive and pre-loaded with Yosemite (version 10.10.1). My "old" iMac is a 2.16 GHz Intel Core 2 Duo vintage 2006 model with 3G RAM and running Leopard and Snow Leopard. I'm trying to learn the ins and outs of my new iMac and Yosemite and I have some questions. Keep in mind that I'm an old dog trying to learn some new tricks, so please be patient.
1. I think I may already have the answer on this one (via the FAQ I read about Fusion Drives) but I'll ask anyway just to be sure I understand. On my previous macs, I've always partitioned my hard drive into 3 or 4 partitions and I would like to do the same with my new iMac. I tried following the Disk Utility Help but I'm running into a problem. Apparently I can only partition my fusion drive into two partitions. If I try to further partition either of those partitions I find I can only merge the existing two partitions back together. According to the Disk Utility help file, I should be able to create as many partitions as I want. So which is correct, the FAQ, (only two partition on a Fusion Drive), or the Disk Utility help, (as many partitions as I want)? And if I can have more than two partitions, how do I do that?
2. Related to question 1, I also have an external hard drive (plain vanilla iOmega type) that is connected to my old iMac via USB cable. I use it for backup storage. Will there be any problem using that drive with my new iMac?
3. One of my partitions is for Windows. I know OS X has Boot Camp but my understanding is that a user must restart when switching between OS X and Windows. Is that still true for Yosemite? If so, I'll stick with Parallels.
4. Related to question 3, the help link for setting up Boot Camp indicates I need a 64 bit version of Windows 7. I have a 32 bit version. Is that an issue (keep in mind, I'll likely be using Parallels)?
5. More on Windows. I see there is an option to format a Windows partition as MS-DOS FAT. On my old iMac my Windows partition was formatted as normal Mac OS Extended (journaled) and that works fine. Is there a reason I should format the Windows partition on my new iMac as MS-DOS FAT?
6. I miss seeing the hard drive icons on my desktop, everything seems to be in the dock. Is there a way to show my hard drive icon and any other partitions on my desktop?
7. Of course my biggest job will be to transfer data from my old iMac to the new one. The Firewire port on my old iMac is dead (zapped by lightning a few years ago). What is the best way to transfer data between the two computers? Note, I see a warning in the Disk Utility help file that "to prevent loss of data on your Fusion Drive don't connect it to a mac that's using a version of OS X older than 10.8.5". Is that warning relevant to transferring my data since my old iMac has
10.5.8 and 10.6.8?
That's my first barrage of newbie questions. There will likely be more.
John

Niel,
Thanks for the quick reply. I understand 1, 2 and 3. I'll check with the Parallels people to get full resolution on items 4 & 5. It's a shame about the restart requirement for Boot Camp.
Item 6 is a "duh". If I'd looked further I could have answered my own question.
For item 7 I didn't get a definitive answer to my question about the relevancy of the warning. Is there an issue? For the answer you did provide are you saying i should dump everything from my old iMac onto my external hard drive and then move that external drive to the new iMac and load it? With regard to using a network approach, all I have is airport to my DSL router from my old iMac and then either Firewire or airport from the router to my new iMac. How would I use that setup? I have no other local or remote "network".

G5 IMAC STARTUP FAILURE

When I try to turn on my Imac, several things have happened or can happen.
Grey screen comes up, loud "clicking" sound, fan kicks in, then screen either goes grey, or blue with alternating folders (question mark/os folder), or I get the white screen with grey apple but nothing beyond that. I have read other posts and found some similar circumstances, but I thought I would post anyway. Any help would be greatly appreciated. I purchased my computer in January of this year if that helps at all.

I notice that you have an iMac G5 that are normally delivered with OSX 10.4x (Tiger). How or why did you install 10.3.1? Is that a typo? Apple says you can't install an older version OS than what was originally installed, unless you received a G5 with Panther. In that event, at least update to 10.3.9. Perhaps this might be the source of your problem. From the Apple icon in the menu bar click on "About This Mac" and check your basic computer profile. Click on the "More Info" for greater detail. Do you have a Rev. A or B? If you eventually are able to "boot up", run Repair Permissions in Disk Utility located in the Utilities Folder inside your Applications Folder. With more detailed input from you, more solutions are possible.

New iMac - set up question

I'm just about to take delivery of a new iMac.
At the moment I use Logic 8 on a Core Duo Mac Mini with all the Content (Loops Jam Pacs) stored on an external Hard Drive, which I also record to. My interface is a MOTU 896.
The Mac Mini runs fine in every respect - no crashes or glitches - recording with Logic is fine. I play classical guitar so the silent Mini has been great. I usually have 2 audio tracks for the guitar and a couple of midi tracks for strings etc - keeping it all simple.
Questions:-
a) given that all is OK on the Mac Mini - could I simply Migrate my account and applications to the new iMac using the Migration assistant? Will this also move my MOTU and M-Audio(keyboard)Drivers?
or
b) If I opt for a clean install of Logic 8 onto the iMac, how do I access the content from the External Hard Drive, or should I re-install the content as well as part of the installation?
c) I was planning on daisychaining the MOTU through the hard drive to the iMac. This works fine on the Mac Mini. Would I be better off having Logic and the Content stored on the iMac (now that I will have plently of space) and also record to the iMac - or should I keep the set up as is with the Content stored on the External and also keep Recording to the External Drive?
Any thoughts and suggestions would be much appreciated - Thanks.

Go into your system preferences and click on the sharing, up top you will see the computer name click on it and change it.

Copied Iphoto 9 library to new Imac... question on faces...

Hi,
I have an old macbook with Iphoto 9 loaded. Faces never worked right on the Macbook and after a while, I just gave up.
I bought a new Imac yesterday and spent a while trying to figure out how to get my Iphoto library over to the new machine.
First, I used migration assistant and tried to migrate files from my time machine. It"migrated" the user that is defined on my macbook and the associated folders I specified in migration assistant (music, movies, pictures). I thought it would just populate Itunes, Imovie and Iphoto, but it actually just copied user "Mike" (my name is the user on my macbook) and the files, and then I couldn't even get at them (had some message saying they were locked or I didn't have permission or something to that effect)! I thought it would automatically populate Itunes, Imovie and Iphoto with all my stuff from the time machine... but nope.
So, I deleted the user "Mike" from my Imac since it was unaccessible anyway.
Second, I decided to open Iphoto 11 from the new Imac and use the "import photos" command from there. I navigated to the image folder on my Time Machine and imported that way. I got closer this time... but it imported 32,000 images when all I have is ~6000! Tons of duplicates and triplicates were loaded! Doh. Round 2 was a bust.
Third, I decided to delete the Iphoto library on the new Imac (since it now contained 32,000 images) and instead, straight up copy the Iphoto library from Time Machine and paste it into the approrpriate directory (this was midnight, so a little fuzzy, but think it was just in user>pictures... can't remember if there was an "Itunes" folder or not.) Regardless, the Iphoto library seems to have copied over OK! When I opened Iphoto this morning, it gave me a messahe about upgrading my Iphoto Library, but once that was done, all 6000 pictures were there, with all the events, etc. So everything seems just fine.
So really, 2 questions:
1) Was this the right way to have done it all along or did I screw something up now that I will pay for later? And if so, how should I fix it?
2) I want to wipe out my "Faces" and start from scratch. The "Faces" that are there now are left over attempts to get the Faces in my Iphoto 9 working (basically, it didn't work at all and the only phots in the folders are ones I manually put in there), and just want Iphoto 11 to do its thing without any legacy '09 attempts. How do I wipe out what is in the Faces Corkboard and let Iphoto 11 go to work with identifying faces from scratch?
Sorry for the long post, but figure some background would be helpful!

The correct way to move Library is to copy it to the new machine and just open it. You got it right at the end.
Just erase the Faces. Select a Face and go command-delete
Regards
TD

G5 Startup issue - question mark folder

Hello -
I am using a PowerMacG5 Dual 2.3 ghz with 1GB RAM
OS 10.4.9
No partitions or anything - just one large hard drive.
It has started having an issue on startup :
For a second, it shows the Flashing question mark folder, then starts up as normal.
Not sure how long this has been happening, or what triggered it.
It runs fine otherwise, except for not recognizing its Airport card.
Latest Repair Permissions returns only the folllowing :
Repairing permissions for “Macintosh HD”
Determining correct file permissions.
Permissions differ on ./private/var/log/secure.log, should be -rw------- , they are -rw-r-----
Owner and group corrected on ./private/var/log/secure.log
Permissions corrected on ./private/var/log/secure.log
Permissions repair complete
The privileges have been verified or repaired on the selected volume
But I want to avoid this becoming a larger issue - why would it be doing this Question Mark on startup and what can anyone recommend - clean install ? upgrade to 10.4.10 ? other ideas ?
Thanks

Hi infoAP-
It sounds like it may be looking for a startup disk, doesn't find what it is looking for, and resorts back to the system drive.
Take a look at your Startup Disk preference and make sure the drive of this particular mac is selected, unless you want it to boot from something else.
Luck-
