Startup problem - iMac won't boot up, I keep getting the flashing ? mark

Hi,
I was wondering if anyone can help me. I have just restarted my iMac as it was running really really slow. Since doing this it won't now boot up. Eventually I get the flashing question mark and folder icon. I have tried restarting holding down Alt and it brings me to a menu but no hard drive showing to point it in the right directions. Resetting the PRAM doesn't seem to do anything either.
Does anyone have any ideas?
Thanks, ArchieA

Hi, Archie. Welcome to Apple Discussions.
Disk Utility is found in the Utilities menu in OS X 10.4.
Here are links to a couple of articles on recovering from the flashing question mark:
http://docs.info.apple.com/article.html?artnum=58042
http://www.bombich.com/mactips/openfirmware.html
If nothing there helps, you may want to ccsgraphic's suggestion to post in the iMac forum or the OS X Tiger forum.

Since you have Lion v10.7.4 installed, use Lion Recovery to repair the startup disk if necessary, or reinstall the Mac OS X.

My iMac won't boot. I only get a white screen. Won't open in safe mode or recovery mode. Any suggestions?

If you can't boot from your installer DVD, then take it in for service.

I have started having trouble since i had to upgrade OS the latest in July 12.

My 27" imac won't boot in normal mode. The screen stays white. I have upgraded to Yosemite. However, the computer does boot in safe mode. Could this be a virus related issue or possibly a video card issue?

My 27" iMac will not boot in normal mode. The screen stays white. The computer will boot in safe mode. Could this be virus related or is it possibly an issue with my video card. Before this happened, my computer screen was flashing weird things and the computer would unexpectedly power down.

1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve the problem. But with the aid of the test results, the solution may take a few minutes, instead of hours or days.
Don't be put off by the complexity of these instructions. The process is much less complicated than the description. You do harder tasks with the computer all the time.
2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. Backup is always a must, and when you're having any kind of trouble with the computer, you may be at higher than usual risk of losing data, whether you follow these instructions or not.
There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
3. Below are instructions to run a UNIX shell script, a type of program. As I wrote above, it changes nothing. It doesn't send or receive any data on the network. All it does is to generate a human-readable report on the state of the computer. That report goes nowhere unless you choose to share it. If you prefer, you can act on it yourself without disclosing the contents to me or anyone else.
You should be wondering whether you can believe me, and whether it's safe to run a program at the behest of a stranger. In general, no, it's not safe and I don't encourage it.
In this case, however, there are a couple of ways for you to decide whether the program is safe without having to trust me. First, you can read it. Unlike an application that you download and click to run, it's transparent, so anyone with the necessary skill can verify what it does.
You may not be able to understand the script yourself. But variations of the script have been posted on this website thousands of times over a period of years. The site is hosted by Apple, which does not allow it to be used to distribute harmful software. Any one of the millions of registered users could have read the script and raised the alarm if it was harmful. Then I would not be here now and you would not be reading this message.
Nevertheless, if you can't satisfy yourself that these instructions are safe, don't follow them. Ask for other options.
4. Here's a summary of what you need to do, if you choose to proceed:
☞ Copy a line of text in this window to the Clipboard.
☞ Paste into the window of another application.
☞ Wait for the test to run. It usually takes a few minutes.
☞ Paste the results, which will have been copied automatically, back into a reply on this page.
The sequence is: copy, paste, wait, paste again. You don't need to copy a second time. Details follow.
5. You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode, under the conditions in which the problem is reproduced. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
6. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply. Don't log in as root.
7. The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in the browser window, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.
Triple-click anywhere in the line of text below on this page to select it:

Copy the selected text to the Clipboard by pressing the key combination command-C.
8. Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Click anywhere in the Terminal window and paste by pressing command-V. The text you pasted should vanish immediately. If it doesn't, press the return key.
9. If you see an error message in the Terminal window such as "Syntax error" or "Event not found," enter
exec bash
and press return. Then paste the script again.
10. If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important. If you don't know the password, or if you prefer not to enter it, press the key combination control-C or just press return three times at the password prompt. Again, the script will still run.
If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that requires administrator privileges.
11. The test may take a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, there will be nothing in the Terminal window and no indication of progress. Wait for the line
[Process completed]
to appear. If you don't see it within half an hour or so, the test probably won't complete in a reasonable time. In that case, close the Terminal window and report what happened. No harm will be done.
12. When the test is complete, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
At the top of the results, there will be a line that begins with the words "Start time." If you don't see that, but instead see a mass of gibberish, you didn't wait for the "Process completed" message to appear in the Terminal window. Please wait for it and try again.
If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
13. When you post the results, you might see an error message on the web page: "You have included content in your post that is not permitted," or "You are not authorized to post." That's a bug in the forum software. Please post the test results on Pastebin, then post a link here to the page you created.
14. This is a public forum, and others may give you advice based on the results of the test. They speak only for themselves, and I don't necessarily agree with them.

TS1367 my mac pro won't boot up, it keeps showing the circle but then shuts off. I've disconnected everything and it keeps doing the same thing.

I have a mac pro desktop and it won't boot up, it keeps freezing at the circle and then appears to be loading and then it shuts off. I've turned it off and disconnected everything and reconnect and it does the same thing.

I wasn't aware PRAM batteries did any charging
Apple has used rechargeable batteries for volatile storage for some time.
and just 'held' information in NVRAM and PRAM when needed and there was no power coming in
I can't see data held in NVRAM/PRAM doing something like keeping time without some power. One can't assume a permanent Internet connection to update it when the system is turned on now can we?
I assume it is on a 1000VA UPS that has good battery and fully charged too, and didn't discharge during the vacation
If the UPS was turned off it's as good as being totally unplugged so it may well have still been at 100% upon return. There's no power delivery when the UPS is off remember.

IMac won't boot after iTunes Match - Get diskos2 i/o error. Help!

So after almost 24 straigth hours up uploading songs to iTunes Match, I woke up this morning and my iMac wouldn't boot. Gets stuck on the gray screen with the apple logo. I booted in verbose mode keep getting a "diskos2 i/o error." With a little googling some people say it's a bad sector and to erase and reinstall Lion others say it's a failing hard drive. Disk Utlity in Recovery Mode says the drive is ok. Any thoughts out there on what I should do? Thanks!

I am having the same problem. The machine loads just to the point when it says "Loading Mac OSX", then its non responsive for hours. The keyboard and mouse still work, but it won't move past that point.
When I try to repair the disk, it gives me an error message indicating that the disk cannot be repaired. I am bad at backing up my files, so I want to avoid a fresh reinstallation.
The worst part is I had just purchased Disk Warrior, and that won't boot up.
If no solutions are found, does anyone know a way that to initiate the computer in disk mode, so I can hook up another Mac to it, and save all the files?

Satellite Pro A10 won't boot up - Where to get the disks

I have a Satellite Pro A10 which currently won't boot up Windows (XP) as it says
The following file is corrupt or damaged:
C:\Windows\System32\Config\System
The Tools & Utilities CD-Rom which came with my laptop has unfortunately been scratched and won't boot.
I have the two System Recovery Disks, which are fine.
My questions:
1. Is it possible to purchase a replacement Tools & Utilities CD-Rom?
2. If so, where from?
3. Is there a way of restoring my laptop without having to completely reinstall everything and lose all my files?
Thanks
Message was edited by: Stuart_2007

Regarding the point;
a) Usually it should be possible to order the Tools & Utilities CD-Rom but I ask why?
b) You can purchase the CD from the ASP in your country
c) The older recovery CD supports an expert mode. You can use this mode to choose the partition where the OS should be installed. In such case only this partition will be formatted.
But listen dude. You dont need to order the Tools & Utilities CD because on this CD you will find only the Toshiba drivers which can be downloaded from the Toshiba page too.

I downloaded a TV episode and it looks like it is basically completed (the line is almost at the end) but the download won't finish and I keep getting the message "Download error, tap to retry" which doesn't work. I've tried everything. Any suggestions?

I've tried rebooting, closing out and reopening iTunes, and even tried to repurchase the show in HD (which the iTunes Store won't let me). Any input would be greatly appreciated!

I'd report the problem to the iTunes Store.
Log in to the Store. Click on "Account" in your Quick Links. When you're in your Account information screen, go down to Purchase History and click "See all".
Find the item that is not downloading properly. If you can't see "Report a Problem" next to the entry, click the "Report a problem" button. Now click the "Report a Problem" link next to the item.
(Not entirely sure what happens after you click that link, but fingers crossed it should be relatively straightforward.)

My iPhone 5 won't restore, and I keep getting the error messages "9" and "1600."

So, today has been a disaster for my poor little iPhone. I have been at football camp all day, and my phone has been tucked away in my bag, so no physical damage was done to it whatsoever. At about 3:30, I checked it and it was working fine. At 4, when my camp ended, my phone was dead - with 80%+ battery. It wouldn't display anything, not an Apple logo, not a charge logo, nothing. So, I tried restarting it by pressing the home button and sleep button together for 20 seconds, and it didn't work. I tried doing it for 60 seconds, and it didn't work. So, finally, I get home and plug my phone into my wall charger in hopes of reviving my iPhone, and still no luck. So I've reached my last resort and I plugged it into the computer to restore it. I finally got it to show up, and didn't think there would be any problems. I started getting it restored, and no luck. I got error message 9. I thought it was just unlucky, so I tried again. This time, the process had went a little further, enough to display an Apple logo on my screen, but then I got error message 1600. Ever since then, I've been getting those error messages. I've tried everything. I've rebooted my Mac, changed USB ports, everything. Does anybody know what it might be? I know what both errors mean, and the problems that they are depicting aren't actually happening. Any help would be greatly appreciated.
Cheers,
Cole

Hi Cole,
I did some checking around and this article has some information on your error messages:
iTunes: Specific update-and-restore error messages and advanced troubleshooting
http://support.apple.com/kb/ts3694
Error 9 says:
Error 9
This error occurs when the device unexpectedly loses its USB connection with iTunes. This can occur if the device is manually disconnected during the restore process. This issue can be resolved by performing USB troubleshooting, using a different USB dock-connector cable, trying another USB port, restoring on another computer, or by eliminating conflicts from third-party security software.
Error 1600 says:
Error 1600, 1601, 1602
Follow the steps listed above for Error 1604. This error may also be resolved by disabling, deactivating, or uninstalling third-party security, antivirus, and firewall software. See steps in this article for details on troubleshooting security software.
The steps for 1604 are:
Error 1604
This error is often related to USB timing. Try changing USB ports, using a different dock connector to USB cable, and other available USB troubleshooting steps (troubleshooting USB connections. If you are using a dock, bypass it and connect directly to the white Apple USB dock connector cable. If the issue persists on a known-good computer, the device may need service.
If the issue is not resolved by USB isolation troubleshooting, and another computer is not available, try these steps to resolve the issue:
Connect the device to iTunes, confirm that the device is in Recovery Mode. If it's not in Recovery Mode, put it into Recovery Mode.
Restore and wait for the error.
When prompted, click OK.
Close and reopen iTunes while the device remains connected.
The device should now be recognized in Recovery Mode again.
Try to restore again.
If the steps above do not resolve the issue, try restoring using a known-good USB cable, computer, and network connection.
If all else fails, this article should allow you to fully restore the phone:
iOS: Unable to update or restore

I hope this helps!

My nano won't sync and I keep getting the error code 13019

I had a computer crash and have been trying to move all of my itunes library over to my new computer. I got that accomplished today, added new music and got my itunes library all filled up how I want it but now it won't sync with my ipod. It says "This Ipod "Jessica's Ipod" cannot be synced. An unknown error occurred (13019)."
Any ideas on what could be the issue here? I've done all the basic troubleshooting including: resetting my ipod, making sure I have the latest itunes availalbe, restarting my computer, trying different USB ports and I even restored my ipod to factory settings to see if it would help. Now all I'm left with is an empty Ipod.
Any help would be greatly appreciated.

I've done all the recommended steps from other posts similar to this and NOTHING is helping.

ITunes store won't connect. I keep getting the "Accessing iTunes" when I try to connect.

I have been having a problem getting my iTunes to connect. It just stopped one day, no idea why. I have tried to fix this by uninstalling, and I have tried to fix it by going through my firewall. I have restored my programs, but that didn't work either. I looked on some Apple discussions and tried the wonsock restore and that didn't work. I read an article about winsock providers, but I am not computer literate enough to know what to do next.
Below is an image of what I get when I run autoruns.exe. I cannot uncheck or delete the non-Bonjour winsock programs, and I'm at a dead-end.
Can anyone help me?

IMac won't boot, won't start in safe mode

I'm at my wits end. My 17" iMac G4 won't boot. I just get the Apple logo, with the spinning progress wheel. I get the same thing when I try to boot in safe mode -- it just sits there with the progress wheel spinning. (I waited an hour, just to make sure.)
Here's what I've tried:
First, I read various articles on the Apple Web site which, among other things, talk about bad fonts, etc. All of the tips rely on safe mode, so I didn't get too far.
I was able to see the iMac HD from my PowerBook by launching it as a target drive, via "t", using a firewire cable. I used Disk Utility to do a repair on the iMac HD. It did find problems (I don't remember what they were), but when I ran it again it said there were no problems with the HD. I can move files from it to my machine, and browsing it looks normal. I looked for non-standard StartupItems, as recommended, but didn't see anything that isn't on the PowerBook.
I also tried putting my install disk in the iMac as it booted. The DVD went in, but had no effect on startup. (Same symptoms.)
Is there any way I can re-install from my PowerBook -- i.e., can I somehow run setup from the PowerBook on the firewire-connected iMac?
I'm not sure of the exact version of the OS it's got, since I can't boot it to see. (Should I look somewhere on the HD for that information?)
Any ideas or suggestions?
Thanks!

IMac won't boot after power failure during 10.5.6 update

Help!
Tried to update last night and at something like 80% install, we had a power cut. iMac won't boot at all now - get to a grey screen which tells me to restart. Don't have a wired keyboard. If I did - what are the steps to get this working again.
I believe I have a good backup, but don't want to risk as all the family photos are on the iMac.
Thanks in advance.

Thanks for the help, but can't even get to a screen where I could type anything! I know I'm being dumb here.
