IMac won't start in Target Mode

I'd like to retrieve some large files from my older Intel iMac, but it won't start in Target Mode. It ignores the key and starts normally. Any thoughts appreciated.

Zap the PRAM and Reset the SMC, then try getting into TDM. Otherwise, see transfer files for other connection options.

  • Imac won't start up n issues in single user mode

    Imac won't start up after long time 'frazing' of Firefox. Manual start up ended up in the grey screen forever'processing' icon.
    Had a look at other solutions, unable to enter safe mode. Someone mentioned to try single user mode and it went through half way  with error messages on the screen which has no command line available for me to key in any letter.
    My Imac has been out of warranty coverage for a while, how do I know if it's hard ware problems before paying for service?
    Any help would be appreciated!

    Yes, I have backed up and deleted old files using target disk mode with an old macbook.  It's just the larger files I didn't have enough space and disks for.  I really appreciate your help on this as I've never had any mac issues before this so am not really sure what to look for.

    help mi imac won't start normally

    Hello!
    Can you tell us what happens?
    I’ve offered the steps below to similar posts in the past and they helped out getting to the solution (or at least find the cause). I suggest them to you too in this case. It will take you about 30 minutes or less to do these, depending on how bad the problem on your Mac is.
    The goal here is to boot your Mac to the so-called Recovery partition where you’ll have a chance to repair the disk and the disk permissions using the Disk Utility and Password Utility. This might solve your issue and even if it doesn’t- it’s still a decent maintenance step to perform. These steps won’t erase your data or reinstall your Mac in any way if you follow instructions carefully.
    Here’s how:
    1/ Make sure your computer is completely shut down.
    2/ You’ll have to be quick next: Press the Mac’s power button. As soon as you either hear the loud chime, or see the display light up - usually after a second or 2 - on your keyboard press [cmd] + [r] Keep these keys on your keyboard pressed until you either see an Apple Logo with a loading bar or a spinning gear.
    After a few minutes, you’ll be presented with a Utilities screen. This is the Recovery partition. If this step is already giving you problems, try using a USB-keyboard. It doesn’t have to be an Apple-keyboard. If you have a Windows-tailored keyboard laying around, use the “Windows-flag” key in stead of the [cmd]-key and it should also work.
    3/ Choose Disk Utility and click [continue]
    Disk Utility will display your computer’s harddrive in the left column. The default name for it is “Macintosh HD” and is usually the second one from the top. Click on it and click on the [verify disk] button. This will check your “Macintosh HD” harddrive partition for errors. If found, click [repair disk]  unless you have a Fusion drive in your Mac and it says [fix] instead of [repair disk] please tell us before you continue! For a screenshot of what I mean, check this article from Apple: http://support.apple.com/en-us/HT202574
    4/ Once done with the verifying or repairing of your “Macintosh HD” click [repair disk permissions]
    This will check your partition for permissions errors. A common myth about this feature is that it will fix all permissions issues on your Mac, which is not true, but it will fix most systemwide issues. Also, here is a list of error messages that you can safely ignore if they pop up:
    http://support.apple.com/en-us/HT203172
    5/ Lastly we shall do a permissions/Access Control List repair on specifically your user’s home folder with a somewhat hidden tool in the Recovery partition. Close Disk Utility and find the menu called “utilities” in the top left corner of your computer’s display. It’s in between the menus “edit” and “window” Don’t be confused with the menu called “os x utilities” 
    Choose Terminal. A somewhat old-fashioned looking window will pop up, waiting for a text command from you. This is the Terminal.
    After the # type: resetpassword and press return. Note that there is no space between ‘reset’ and ‘password’ 
    What you’ll see next is an rectangular window that gives you the option to reset passwords. We are not going to that, however. Instead, click on “Macintosh HD” at the top. In the pull-down menu below that, choose your user's accountname. Skip all the rest and at the very bottom click the [reset]-button.
    A spinning gear will appear and may stay on for a second or several minutes. It’s hard to predict exactly how long.
    If you have multiple users on your Mac, I advise you to repeat this step for all your users.
    We’re ready to reboot your Mac now. Click on the Apple Menu and choose “startup disk” Choose to boot from “Macintosh HD” Please let us know if this solved your issue, or if the steps above did not work, or could not be performed for some reason.

  • IMac won't start up passed the grey screen

    Last friday my iMac (late 2006, 24", 2.33 duo core Intel, OS 10.6.8) gave me the spinning beach ball.
    Restarting resulted in: first the apple screen with the progress indicator, followed by grey screen..
    That was it. It hangs at the grey screen.
    I've been busy this weekend testing all kinds of ideas to get my imac to fully start up again.
    I checked the RAM, it's fine.
    I flushed NVRAM, wild guess, but nothing changed.
    Starting up in safe mode doesn't work.
    Starting up in recovery mode doesn't work.
    On the upside, I was able to start my imac up in Target mode. Using the host computer and Disk Utlity I can see there's nothing wrong with the HD. All the data is still there!, so later today I'll make a copy of the complete HD, hoping/thinking that I won't copy whatever is wrong.
    I had Disk Utility repair all the permissions.
    I've used the host computer to reinstall the OS on my imac.
    But on start up my beloved iMac still won't get passed the grey screen.
    I'm thinking something goes wrong before my Mac even gets to the HD. Maybe it's the firmware, but I'm not really sure that firmware matters in this case. And I wouldn't know how to reinstall the latest version of firmware because my imac won't start up from it's disk drive
    I'm thinking maybe something could be wrong with the graphic card's RAM, though on start up I can see the apple logo just fine.
    I'm not able to start up from CD, I've tried that because I wanted to reinstall my OS (before I figured out how to do that in Target Mode) by putting the OS disk in my imac's own disk drive. Staring up with the C key still gets me the grey screen. Staring up with Option key shows no other option but the HD.
    So is there anybody out there who has an idea that could help me further along?
    Any help is greatly appreciated!
    Frank

    Hi Jan,
    If you have another firewire Mac you can check if the HD of your Mac is OK by connecting them with a firewire cable and use target-mode. That way I found out my HD was just fine.
    It also offers you the chance to run a diagnostic program to check if anything else is fine. I used TechTool to do that. But everything checked out fine.
    In the end I decided the problem is probably hardware. Some electronic part that broke. Very frustrating that some small transistor or so is keeping me from using my otherwise fine iMac.
    I contacted a repairshop that also works for the local Mac retailer. They told me my iMac was concidered 'classic' and therefor it wasn't economically not worth the trouble trying to repair it.
    I gave up, took two weeks to mourn the loss of my beloved iMac, and bought a Mac mini.
    FrankV
    Judging by your name I'm guessing I could've anwered this in Dutch.

  • HT1767 iMac won't start up.

    My iMac won't start. When you turn it on the apple logo comes on but it keeps trying but never turns on. I tried unplugging it and plugging it into a new power source didn't work. I tried starting it up in safe mode didn't work. Any ideas out there?

    There are some good Apple Support articles about startup issues, but which one to read depends on your operating system and model.
    For example, if you are running 10.1-10.4, this one is good: Resolve startup issues and perform disk maintenance with Disk Utility and fsck
    Here's one for 10.4-10.6: Mac OS X: Gray screen appears during startup (I know the apple logo is showing up for you, but good things to try anyway).
    If you decide to run fsck as mentioned in the first article, be sure you read this article first: Mac OS X: How to start up in single-user or verbose mode
    Regardless, are you in fact running a late 2009 iMac? If so, it's an Intel mac, and you're in the wrong room. You'll want to move your post to the Intel iMac community which has more active users. Remember to post your OS.

  • 24" iMac won't start when iPod is connected

    My 24" iMac won't start up/restart if my iPod is already connected to it. If I restart with the iPod connected, I just get a gray screen (with no apple logo) forever. Has anyone else experienced this problem? If so, any solution? I have Windows installed with boot camp, don't know if that's the problem, but I tried reseting the p-ram, but to no avail...
    Intel iMac 24", 7600 GT, 500GB, 2GB. Titanium Powerbook 667 MHz G4, loaded.   Mac OS X (10.4.7)   30 GB iPod Video

    My suggestion would be disconnect the iPod. That's just me though.
    http://docs.info.apple.com/article.html?artnum=93953
    I'm guessing Boot Camp is the culprit. Whatever emulated BIOS it's using doesn't like the iPod as a startup disk.

  • IMac won't start with Thunderbolt Display connected after firmware update

    After updating my thunderbolt display firmware to version 1.2 this morning via the App Store, my mid-2014 iMac won't start up with the external display connected.  I can get the iMac to start up only by disconnecting the display's thunderbolt connector. After the iMac comes up, I can reconnect the display and everything appears to function normally.  I've tried several restarts and the iMac won't start up with the display connected.  Anyone else experience this?

  • After installing update, iMac won't start up

    After installing the last updates my iMac won't start up, starts what look like install then just shuts down.

    Would you care to tell us what exact model and version of iMac and what version of OS X you are using?  We need a hint to help you.
    Hope this helps .

  • IMac won't start - should I reinstall OS?

    Recently my iMac won't start up - it goes to screen with folder + question mark. I've run Disk Utility, repaired hard drive, but there were no reported repairs to make.
    Occassionally it will start up, and everything seems normal until suddenly the beach ball appears and everything freezes. 99% of tries it won't start up (i get the ? folder). Is it worth erasing the disk and reinstalling everything to see if a fresh start will help, or is it likely that the hardware is damaged?
    Don't want to bother erasing it if there's no point... any advice greatly appreciated.
    Also - anyone who's had their iMac repaired - what are the costs like?

    I've just suddenly had the same problem - for no apparent reason as far as I can tell. The night before last I switched off my iMac as normal, and yesterday morning switched it back on. At first it would start, but crashed as soon as I tried to start any applications. Then it wouldn't start at all, and just got as far as the gray screen with the apple on it. After trying resetting the PRAM, switching on and holding the on button for 10 seconds, it was no different...
    So, I tried doing a archive-reinstall from the original leopard DVD I bought from apple. This did a successful disk verification, but then said it couldn't install mac os due to a problem with the basesystem package. After that it wouldn't let me try another archive-install and only gave the options to install as new, or erase and install. The latter I don't want to do, and the former just gives the same basesystem error... All I get now is a flashing folder with a question mark and not even the gray screen...
    I have tried using the diskutility to verify/ repair the hard drive and it says all is well...
    I have heard this may all be due to dodgy RAM chips, but I have never messed with them or altered them. It just seems odd they should suddenly fail when they were working fine before.....
    Any ideas would be much appreciated. A lot of data at risk
    Dan.

  • IMac won't start without install disc

    Hi, I'm new to all of this. I tried resetting my admin password using install disc on my iMac as I'd forgotten it. Now iMac won't start without disc. If disc is ejected on restart apple logo flashes between no entry sign and folder with "?" on it. Will start up with install disc in, but then wants me to choose language and install OS. Tried repairing and verifying HD and all seems ok. Tried holding option key and selecting HD on startup, but same outcome - choose language and install OS. How do I get back to normal desk top? Do I have to install OS again? Will I lose data? Please, please help! Thanks.

    It should only take a minute or so at most to boot from the DVD.
    If your sure you have the correct Install Disk for that iMac, I'd start over. Then if it still doesn't work then perhaps a trip to your Local Apple Service Provider with the Disk or Disk and iMac is in order.

    Alternately using the correct Disk as per the following article, see if you can run the Apple Hardware Test? > http://support.apple.com/kb/HT1509

  • G5 iMac won't start! Help needed.

    Got a new intel iMac. Gave my husband my old G5 iMac (not intel). It was working perfectly. For some reason unknown to me, he decided he was going to reinstall everything from scratch so he grabbed the first disk he saw and put it in the computer. It was the startup disk for an intel computer & NOT for the iMac G5.
    Did he fry the computer? It won't start up. Keypad & mouse won't respond.
    The screen can't find the driver (no surprise) and says "panic: we are hanging here...." I can't get the disk out of the drive. Service contract is up. Is there a way I can connect my laptop to it and get it to respond & spit out that intel disk? Perhaps if I open the cover up, I can into the CD drive and get the disk out. All ideas appreciated.

    Hi Mel Kev
    Have you tried holding down the left mouse button when you turn the computer on. Holding down the left mouse button should force eject the disk.
    Hope this helps

  • Intel iMac won't start - HELP!

    My iMac won't start this morning. I get the white screen with the grey apple,
    and the swirling progress thing, then after a few seconds I can hear
    the sound you hear when the system shuts down. like a soft switch
    going off, then it just continues swirling, still with the white
    screen and grey apple, then it restarts by itself. Then we go through
    the same routine. Tried booting up by holding C with the Leopard disc inside but nothing happens.I have just reinstalled Leopard as Snow Leopard left too many printers and programs lifeless, so I did an erase and install a few days ago. Since then I have used the Mac fine, switched down normally last night, but this morning it doesn't want to play.
    Any thoughts?
    Thanks in anticipation

    Have you reset PRAM and SMC?
    Do this first
    http://support.apple.com/kb/HT1379
    and then do this, if the PRAM does not help
    http://support.apple.com/kb/HT1543
    The second one is basically disconnecting your iMac from power (and all cables), then reconnecting following a precise procedure.
    If that does not help, I would restart with the Snow Leopard installation disc (insert disc and start up with the C key held down). You probably did an installation of Snow Leopard over your existing Leopard system the first time. This time, erase it completely first, then install Snow Leopard. I assume you backed up your data already.
    When you get to the Installer screen (after selecting language), go up to the menu bar. Under Utilities, select to run Disk Utility. In the sidebar, select the internal DRIVE, not the volume indented under the drive. Go to the Erase tab. Name the volume +Macintosh HD+ and set the format to +Mac OS Extended (Journaled)+. Erase the drive. Since you have the drive selected in the sidebar (not the volume), it will also re-partition the drive.
    It should take less than on minute to complete the process. Quit Disk Utility to go back to Installer. Run the standard installation onto the blank internal drive. Hopefully, a fresh Snow Leopard install on a reformatted/re-partitioned drive will work better for you.

  • IMac Won't Start Up/Boot

    My iMac won't start up. I've tried holding all kinds of key combinations while I turn it on, but it doesn't even get that far. It gets stuck on a folder with the Apple picture alternating with a question mark. It doesn't do anything else for a while, and then the fan turns on (???).

    This is indicative of a corrupted system or drive. The first thing to try is:
    Repairing the Hard Drive
    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.) 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, then quit DU and return to the installer. Now shutdown the computer for a couple of minutes and then restart normally.
    If DU reports errors it cannot fix, then you will need Disk Warrior (4.0 for Tiger) and/or TechTool Pro (4.5.2 for Tiger) 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.
    If this doesn't solve the problem then you will have to reinstall OS X. If the drive tests out OK per the above then you can reinstall without erasing the hard drive:
    How to Perform an Archive and Install
    1. Be sure to use Disk Utility first to repair the disk before performing the Archive and Install.
    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.
