My iMac will not start up after running on Yosemite since Beta 4

Hi!
I have successfully been running Yosemite since the Beta 4 on my late 2012 iMac (se spec below). But I did notice that the boot process delayed for some time after approx ⅓ of the progress line was passed.
Today it did not pass this point. I had it running overnight, but it would not start up in normal mode.
It does start in safe mode.
I have run diskrepair
I have unplugged all peripherals
I have run the Apple Diagnostics (or AHT), no problem there whatsoever.
Is there anything else I can do except reinstall Yosemite or go to an apple workshop for repair??

I have the same problem (and have posted it elsewhere) and I have already rolled the system back to Mavericks to keep working. That seems to be he only course open for now, but will leave us with an increasingly obsolete system and future problems with new/updated apps. Not only that, but my iMac has plummeted in value.
Faced with a £1000 12-month old iMac that can't be updated, I seem to have an expensive paperweight and am beginning to regret the unkind things I said about Microshaft.
A solution is still needed, and none seems to be forthcoming from Apple.

Imac will not start up after power outage

My iMac G5 will not turn on after the power went out. I can hear a clicking noise which seems to be coming from the fan/power supply area when it is plugged in. Nothing happens when the power button is pressed. Tried resetting PMU and still nothing. What do you think the problem could be? Bad power supply?
Thanks.
iMac G5 17" Mac OS X (10.4.9)

I just went through the steps of troubleshooting with an iMac that won't turn on using the led indicators with the back taken off, the first led light lights but it seems to blink very quickly (in unison with the clicking noise), does not stay solid. After pressing the SMU and then the internal power button, nothing happens again, and the 2nd led light does not light even momentarily. So it tells me that I need a new logic board...what kind of costs are we talking about here, anybody have a ballpark idea? Thanks for the help.

IMac will not start up - blue screen after months of Leopard use

I have an iMac G5 that will not start up. It hangs at the blue screen, but does not have the issue with the ApplicationEnhancer.bundle file. It will start up in safe mode.
This iMac will not start from a bootable external drive (the external drive can be used as a start up disk successfully with my iBook G4). The iMac's internal drive can be used as a start up disk for the iBook (via the target mode) and does not appear to have any problems. Does this seem like it is a hardware issue with the iMac? The iMac also hangs at the blue screen if I attempt to start up with the Leopard install disk after using the startup disk preference pane in safe start mode.
I have repaired permissions, verified the disk, etc., using the disk utility. I have cleared caches, preferences, and so on, using Mac HelpMate.

It may be that some of your login items might be incompatible with the mac. Also, try booting up from the install disk and repair your disk.

G4 iMac will not start normally

My wife's G4 iMac will not start normally. I have used the procedures from http://docs.info.apple.com/article.html?artnum=107393 and the "Disk Utility" on http://docs.info.apple.com/article.html?artnum=106214 to no avail.
When trying to start, a message comes up saying that the computer must be rebooted. Trying to boot in "Safe Mode" fails after an hour and shuts down the computer, and the "Disk Utility" runs for an hour or two and then gives a message that it was unable to repair the "minor error" on the hard-drive.
After force starting the iMac by holding the power button until the command line appears, I tried running fsck, but the commands are unrecognized. However, if I type in "mac-boot" at the command prompt, the iMac will start. I have copied all of my wife's photos, movies and music, and Word and Excel documents, etc. to my XP PC's hard-drive using USB flash drives.
My question is two-fold:
#1. I have heard that "Disc Warrior" is excellent at resolving hard-drive errors. Can anyone comment on "Disc Warrior" and is there anything else out there that someone can recommend?
#2. I bought RAM to bring the total up to one gig, so I was thinking of upgrading the hard-drive and installing Tiger on the new and larger drive while in the "Ball" changing the RAM. What is the maximum capacity hard-drive I can put into the G4 800mhz iMac without any problems and is there any particular model hard-drive that seems to work best?

I tried reading the link that you posted http://www.thexlab.com/faqs/kernelpanics.html but I don't have a disk with the "Apple Hardware Test".
Since I made the post that you replied to, things have gotten worse. I can no longer get onto the internal hard-drive. I have tried many different methods including the methods written about in the linked article you supplied. I can get onto the Installation CD and I can run "Disk Utility" from the CD. I have repaired the file permissions, but when I run "Repair Disk", it runs for about two hours and then suspends operations with a dialog box stating, "First Aid failed. Disk Utility stopped repairing Volume because the following error was encountered: The underlying task reported failure on exit." and then in the progress box after the list of addresses, there is a message:
(in red) Incorrect number of thread records
Invalid leaf record count
Invalid Map Node
Invalid directory Item Count
Invalid directory Item Count
Invalid volume directory Count
Invalid volume file Count
Volume Bit Map needs minor repair
Invalid volume free block count
Volume header needs minor repair
(in green) repairing volume
(in red) The volume could not be repaired
Error: The underlying task reported failure on exit
(in black) 1 HFS volume checked.
(in red) 1 volume could not be repaired because of an error
(in black) repair attempted on 1 volume
(in red) 1 volume could not be repaired.
I recently bought the 1/2gb replaceable RAM and the 1/2gb "Hidden" or "Factory Installed" RAM. I was planning on installing them soon. Since the "Disk Utility" is telling me that there are faults on the internal hard-drive and I have to go into the "Ball" to replace the "Hidden" or "Factory Installed" RAM, I figured that I might as well replace the hard-drive and redo the system.
Unless someone comes up with something I can do which will not cost me much money, I figure that I might as well install the RAM and a 120gb Western Digital Hard-drive that is about a year old, but was only used for a few days in an XP PC. Will the 120gb drive be recognized? I was thinking of partitioning it as 80gb and 40gb partitions. Does that sound good? I would install the OS on both partitions so that I could always boot if there was a failure.

Macbook will not boot up after running Software Update

My MacBook will not boot up after running Software Update (Security update + Java?) earlier today. I have only the gray start up screen + Apple logo + gear wheel constantly rotating. I have tried restarts several times and tried to start up from my original system DVD - this makes no difference.
I called Apple support, tried resetting the power and PRAM - still no difference. He had no knowledge of other problems reported; although I note recent post may have same issue.
I cannot get an appointment at my Apple Store before Monday.
Any suggestions?

Still no success. When I hold down the option key when powering up I get the hard disk icon plus arrowhead (only). When clicking the arrowhead it goes to the gray screen + apple logo+ rotating gearwheel.
This happens both with DVD in slot and without DVD. the DVD image is not coming up on screen. When I start up without DVD the hard disk icon appears promptly. When I start with DVD in the DVD is spinning for a short period before the hard disk icon appears. On clicking the arrowhead to hard disk icon the DVD spins again for a while then stops. Apart from the DVD spinning, both situations result in gray screen + apple logo+ rotating gearwheel.

My imac will not start - it is hunged up, when I turn it on I see the apple and the little wheel go around and around and nothing happens - what can I do ???

Hello - can anybody help me - my Imac will not start - When I try to start it I just get to see the apple and the wheel that goes around and around HELP !!

Restart in Safe Mode, this will clear some caches. How you do this is when you hear the startup tone hold down the Shift Key until you see the progress bar appear. Let it fully boot, then open System Preferences - Startup Disk and ensure your internal HD is selected and then click Restart to test. If you still don't have luck you should run Apple Hardware Test in Extended Mode, you may need to run the test 2-3 times to report any errors. To run AHT you will need teh ORIGINAL Install Discs that shipped with the computer. Instructions for AHT are in:
http://support.apple.com/kb/HT1509
Have you been backiing up?

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.

My brand new iMac will not power up after an update restart, any suggestions?

Any suggestions on why my IMac will not power up after it done a restart?

Try an SMC reset and PRAM reset: https://discussions.apple.com/docs/DOC-3603
If that doesn't help:
See if it will start in Safe Boot: restart holding down the Shift key until you see a grey progress bar, type your admin password when prompted, let it continue to (hopefully) boot. Restart as normal from the Apple menu.
If that didn't help, try booting into the Recovery HD: restart holding down Command+r and choose Disk Utility from the four choices when they appear on screen. Once DU has launched select your Macintosh HD on the left and click on 'repair disk'. If anything gets changed click on repair disk again until you get a clear pass, restart as normal from the Apple menu.
If you still have problems, give AppleCare a call.

Please can somebody help, my imac will not start up, just chimes, apple sign then spinning cog. I have tried many key codes, no success, would really like to talk to someone.

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.

TS3824 iMac will not start and switches off almost immediately

My iMac will not start. It switches off about 3 seconds after pressing the power button. The iMac then starts again, and fails again after 3 seconds. This cycle just repeats.
I have not installed any new software, this seems to happen for no reason.
Any help would be appreciated, as I cannot use my iMac at all.

I thought there was a way to start your iMac in an emergency independent of my hard drive. From a flash drive for example? If this can be done, where can I get the appropriate software to put on the flash drive?
You will need to call AppleCare if you want to speak to them yourself. They don't participate in this forum in any fashion, and no they don't support via email. If you don't have AppleCare you will be charged, otherwise you will need to take it into an Apple Store or AASP. If you don't know how to contact AppleCare or an AASP please start with AppleCare Contact Info
Good luck.

My MBP will not start up after restart

My MBP (late 2011 running 10.8.something - receintly updated) will not start up after I had to do a restart to install Blackberry Desktop software (for my wife, I promise). It chimes, gets past the grey screen with the Apple logo and then just sits on the login screen but with the background only, no account or anything. My mouse pointer is there and moves but nothing else. Anyone have any idea?

Reboot holding the Shift key down on a wired or built in keyboard, this is Safe Mode and will disable the at boot kernel extension file that Blackberry installed.
When you get in uninstall the software using their uninstaller. Then reboot normally again, visit their website for a update if there is one.
Blackberry/RIM software has been causing issues around here lately.
If your machine refuses to boot normally again, then run through this list 1-8,, by #8 your machine should be booting normally again.
Step by Step to fix your Mac

IMac will not start-up, do not have a backup, any way to back it up before erasing the drive?

Our iMac will not start up, it goes to the flashing question mark screen. I have tried the different steps listed at http://support.apple.com/kb/TS1440, but they have not worked, as it says the disk is not repairable. It says I need to erase the disk and reinstall OS X. However, I do not currently have a back-up of the hard drive, so is there any way I can back it up before erasing and reinstalling, even though the iMac will not start up? Thanks.

I also tried downloading Snow Leopard onto an external hard drive and boot from there, but it just comes up to the choose a language screen everytime.

2007 Mac Book pro Shuts down at startup attempt. Tried reloading OSX and will not start up after that.

My Mac Book Pro started having issues. I tried to relaod the operating system and it worked for a moment. When I tried to do a time machine back up it failed.
Now itr Shuts down at startup attempt. Tried reloading OSX and will not start up after that.

Dr.Conga,
did you try to do a Time Machine backup from your MacBook Pro, or a Time Machine restoration to it?
Are you trying to reload your current version of OS X (10.7.4, to judge from your signature), or are you trying to reload the version of Mac OS X that came on the grey installation DVDs that originally came with your MacBook Pro?

My MacBook Pro will not start up after entering correct password.

My MacBook Pro will not start up after entering password. Circle with an X in it and 'cancel' below it is on bottom of screen. When clicking on cancel, nothing happens. This just started last night.

Hi MJTOOTS,
Since you are getting to the login screen, it is booting past the "gray screen" phase, so try the steps in this article, like a Safe Boot.

IMac will not start following OS X 10.9.4 update - takes 30 minutes to load and then turns off

iMac will not start following OS X 10.9.4 update - takes 30 minutes to load with spinning wheel and progress bar and then when it appears to be finished it powers off?

Thanks for the suggestion - this was the 1st thing I tried but it does not appear to work either. I'm still getting the 30 minute spinning wheel and slow moving progress bar on a grey background - even if I try to start the iMac in 'safe' mode!

My iMac will not start up after running on Yosemite since Beta 4
