27-in iMac Late 2009 boots from external HD only

We have a late 2009 27-in iMac running Mavericks (10.9.5) with 8Gb ram and a 1-yr old Seagate 1TB hard drive. We recently erased the drive and performed a Time Machine backup of the entire system from a MacBook Air. The iMac was working fine until yesterday.
On startup, we get the chime, then a gray screen, and eventually the missing startup disk icon (blinking folder with question mark). The iMac will startup and run from an external drive using a clean install of Mavericks but will not startup any other way.
It will not respond to holding the option key, or D, or R. I have pulled and reseated the RAM, and zapped the PRAM (command-P + option-R). I have attempted to startup in Safe mode, and Single User mode, which also do not work.
I'd like to run diagnostics / apple hardware test, but holding the D (or option-D) won't work.
Any ideas what else I can try? or Is it simply the HD has failed?
I'd really like to know if there's anything else wrong (hardware test) before opening it up and replacing the HD again. The nearest Apple Store is 90 miles away.
Thanks!

OOn iMac press and hold "Option" immediatly after Poweron. This should prompt to you disk selection for boot.
othereways you can boot from external device (always in the samewa) and start boot camp to select boot. keep in mind that command+operation+p+r reset the nvram and this also delete boot option to start from other devices.
Let me know If this is your problem

    Can I use my 27"iMac late 2009 as an external display for a non apple product such as a cable box?

    To get TV on your iMac off the cable box you would need to use an external TV tuner device such as the company ElGato is highly regarded for.  I have used one of their EyeTV products for many years with my iMac to watch television shows from my Comcasst cable TV box.  You can look at the models here:

  • IMac 2.8Ghz + booting from external FireWire Drive

    I was wondering if anyone has 'booted' from an external FireWire drive using the FireWire 400 port?
    After going through the issue of reformatting my external drive with the GU-ID partitioning scheme, I found that the drive would mount on the FW400 port but wouldn't boot. In the end I used the FW800 port and the drive booted up first time. On my old PowerBook I could boot from both FW400 & FW800, does anyone know why FW400 doesn't work or is it my iMac?

    If it mounts then you can install OSX or clone OSX and then boot from it. From what you are saying a bootable partition will boot on 400 just not on 800, which is quite odd, I concur.
    Note that they are notorious for needing the right power supply and they all look identical - I had problems of recent with a triple extreme 1 TB on FW 800, and took it to LaCie (a mile from where I work) - they told me I was using the wrong power supply and gave me the right one free. When I got home I did have the right one in a pile with others. 4.2 A vs. 2.2 A and it worked great. And I have a spare free power supply.
    I don't think drivers even enter into it at all with firewire, e.g. drive specific drivers.

  • Cannot boot from external HD

    I have an external HD which my iMac backups my system daily. I use CCC for that and it has run fine so far. I never had any problem booting from that HD either by using Option/Alt during booting or thru using System Preferences.
    Not now anymore. The iMac (late 2013, 27", FusionDrive) refuses to boot from it.
    In System Preferences I can see the external HD as a bootable device. However the iMac still uses the internal drive.
    When using Option/Alt I only see the internal drive and the restore partition.
    I have made a (new) full backup to the external HD and CCC says it "blessed" the HD. But not possible to boot from. Further I did things like resetting Pram, resetting SMC. But does not help.
    So next I installed the iMac from scratch (meaning starting the Internet restore and then do a full erase). But still the iMac will not boot from external.
    I have connected the external HD to another Mac (Mini) and there it boots flawlessly. So to me there must be a problem with the iMac. But what can I do, this is a serious problem since I now have a backup but this can not fully be used?

    - The issue is only if you want to boot from a USB3 external device. 
    - There are other ports on your machine that you can boot from, refer: Startup Manager: How to select a startup volume
    - The ASC is not where Apple make announcements, Refer to their main website.
    - Your question / query / feedback should be referred to : https://ssl.apple.com/support/feedback/
    - If you find from Apple a resolution, post back.  We would like to hear !

  • Why no airplay mirroring for imac late 2009

    Just upgrade to find the key feature Airplay Mirroring is not supported for my iMac late 2009. WHY??

    Only some 2011 machines and newer are supported (excluding any Mac Pros).
    The best theory is to do with onboard h264 encoding in Ivy Bridge and Sandy Bridge Intel chips:

    It seems likely that Apple feel a software only solution would not be feasible/acceptable on earlier models though Airparrot puts that in doubt.

  • Constant Disconnection from Airport Extreme Networked iMac (late 2009)

    I keep trying to copy fairly large files (2-7GB) over my Aiport Extreme (latest—5th generation) network from a early 2011 Macbook Pro to a 27" iMac (late 2009), and I keep getting disconnected from the iMac while the file is copying. I've tried repairing permissions on every computer in the house and restarting them, but I'm still having issues. I have no issues copying files to another late 2011 Macbook Pro in the house, so it seems to be happening only when I copy them to the iMac. The iMac is running Snow Leopard and the Macbook Pros are running Lion, so could that have something to do with it?
    Additionally, I had been trying a wireless extended network with another previous generation Airport Extreme, but I found the connection wasn't much stronger with the extension, so I've just been leaving the second Airport Extreme unplugged. I've had that unplugged for months and haven't had any issues, so I don't think that's the problem.
    I'm hoping this isn't a sign of something being wrong with the Aiport card in the iMac. Anyone have any ideas?

    Bump?

  • Why won't my iMac 27" boot from external hard drive?

    I have a new 27in Intel i5 dual core 3.6GHz iMac. It works wonderfully.
    My question is this. I have a Pleides Ice Cube external hard drive with a USB 2.0/Firewire enclosure with a 500GB hard drive. I used diskutility to format the hard drive as a GUID Partition Table. I then used SuperDuper to clone the iMac OS 10.6.7 and Apps over to it.
    I can select the external drive in System Preferences/Startup Disk to boot from, but when booting the iMac gets as far as the white screen then just stops loading.
    I have tried both the USB connection and the Firewire connection (with a Firewire 800 to 400 cable).
    I have run Disk Utility and repaired the disk and the preferences.
    I have used Disk Warrior to rebuild the directory as well, but the iMac will not boot from the drive.
    It does boot from the original DVD's and its own hard drive.
    My old 24" iMac had no trouble booting from this hard drive or any of the others I have collected over the years, so I am reluctant to think it is the external drive. It is something to do with this particular processor Snow Leopard and external drives.

    It sounds like something in the SuperDuper clone might not have copied well. To get the full answer on that I would check with Apple or SuperDuper to see if they support each other.
    As a quick test, if you restart and immediately press and hold "option" on your keyboard do you see your external HD as an option to boot from? If so, click it and see if the boot runs any differently, but if you don't see it at all that could show that the problem is more deep rooted.
    Personally, if looking in to either of those didn't give me any other info to go on, I would reformat and start the clone again. BTW, do you know for sure GUID Partition is the format you'd want to do this on? Generally macs use "Mac OS Extended" and some external HDs can use "FAT32" (if you want them to work well with Windows)
    Hope that gives a little direction

  • How to install windows 7 on Imac late 2009 using Vmware/Vbox

    Hey guys. Here's the thing. I've installed Windows 8 on my imac late 2009 but then i realized that there's no bootcamp drivers for it (check image).
    everything works fine except for the video drivers that crash everytime when i install any driver (bootcamp or manually).
    So I've searched on many forums n i found a guy that could do that by using Vmware/Virtualbox by accessing the full disk n installing it from there.
    Here's what we wrote -> (http://forums.macrumors.com/showthread.php?t=1526883)
    "Thanks for the suggestions, but installing from usb wasn't working, and refit didn't recognise the external dvd drive too (it was in the list, but when i tried to load it i got an error).
    But i found a solution, not usual procedure but still good and easy to do.
    I installed virtualbox, created a virtual machine with the full disk access (you'll have to unmount all the partitions first and run virtualbox as root), started installing windows, when the copy of the files ended and the vm was rebooting i simply closed it and rebooted my imac and finished the installation directly on the imac, everything went well...
    Thanks again for the help"
    Important notes :
    - My superdrive is broken
    - I can't boot efi windows 7 (cause it needs efi 2.0)
    So i might ask u 2 things..
    1- Is there a way that i can install all those drivers on windows 8.
    2- Can u describe how he did that with Vmware/Virtualbox?

    I can't. Just like i said. My superdrive is broken so the only way is to boot from usb but my imac's efi firmware is 1.0 and to boot a windows 7 efi you must have at least efi firmware 2.0. I managed to install windows 8 cause it needed efi firmware 1.0 that's why.

  • IMac late 2009 crashing with Maverick

    I have a problem with my iMac (late 2009) that I cannot solve. It has become very slow, and crashes regularly after some time. Impossible to repair it, neither from the disk recovery partition, nor an external HD boot and using Disk Utility. So everytime I have to download Maverick again and install it to be able to work. I have noticed that after the fresh installation, and and a few days of working, Disk Utility shows problems with Disk permissions that need to be repaired. This occurs systematically.
    To complete the story, the iMac was working fine when I bought it, but was returned to Apple for the HD substitution (Apple replacement programme). After this, and/or after installing Maverick (but I am not sure the 2 things are related), the problem started.
    I have also tried PRAM resetting, no effect. Any suggestion?

    For 2009 iMac owners on Mavericks, I recommend this procedure. Saved me a lot of frustration after almost a month of constant crashes and getting no work done.
    I downloaded a temperature monitor to see what was happening. Before the fix, the temperature on the "north bridge heat sink” would just go up and up without fail. Particularly when using flash or a video related application. It would just keep rising until until the graphics card just shuts down.
    It’s a 3 year old bug related to 10.6.3 and GPU drivers (ATI/AMD). Here’s the link to the guy who figured it out and should be testing for apple. You have to use terminal to solve the issue. He explains everything in detail.
    http://www.pauloamgomes.net/blog/fix-weird-os-x-freeze-imacs-late-2009
    After the fix, the temperature at the graphics card stays level. I’ve also decided to use a fan control app for the moment so temperatures stay around 50 and the iMac runs like it should. Even in my hot room in the summer.
    Been crashless since doing the procedure. Try it out. better than lugging a 27" iMac around town.

  • IMac late 2009 gives beach ball. All test return normal.

    I have an iMac late 2009 model 27 inch. update to Mavericks (10.9.1)
    Returning from holiday, I found my iMac dead slow, with spinng beach balls on every click. Until now I have done ....
    Create new user account, logged in as this new user.
    reset PRAM / NVRAM
    boot up in safe mode
    boot up in recovery mode, perform disk test. (all normal)
    I managed to copy the most important directories to an external storage. Got more and more read/write errors.
    iMac had become unusable slow.
    Made bootable USB stick, used this to boot and did a complete HD erase.
    Clean installed Maverick.
    Problem still persist.
    Performed AHT (Apple Hardware Test) in extented mode. No error founds.
    Performed Black Magic Disktest, around 110 MB/s seems normal speed.
    After reboot, the first application start up fast (which gives me hope) but starting the second app, takes several minutes with this spinning beach ball.
    Anyone here having simular problems or otherwise can point me to a solution?

    Thanks for you advise. I did a clean install, so without any third party software like Trusteer Rapport.
    On you advice I ran EtreCheck. This is the result:

  • IMac Late 2009 i7-2.8Ghz Poor Performance

    My iMac Late 2009 seems to run very slowly after a clean install of OSX Mavericks. I am not sure that happened after the clean install. But now i have noticed it.
    I am using mainly photoshop. Everything is sluggish. Moving or resizing layers.
    Generally it runs very slow with everything.
    The surprising fact is after i ran GeekBench.
    The average score for 32-bit test is about 2000 for single-core and 7000 in multi-core
    My results are: 700 for single-core and 3000 in multi-core.
    Few users seem to have about the same results as me..
    My specs are:
    Late 2009 iMac
    intel i7 2.8Ghz
    12GB of Ram
    ATI Radeon HD 4850 512 MB
    Kingston SSDNow V300 120GB with trim enabled (i upgraded my ssd after my old corsair 90GB ssd broke!!!)
    OSX Mavericks 10.9.3
    You can see all the iMac Late 2009 i7 2.8Ghz results here.
    http://goo.gl/yuoQvm
    Do you have any suggestions?
    it drive me crazy!!
    I am considering a clean install but i want to wait for the Yosemite release.

    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 merely by the seeming 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. All it does is to collect information about the state of the computer. That information goes nowhere unless you choose to share it. However, you should be cautious about running any kind of program (not just a shell script) at the behest of a stranger. If you have doubts, search this site for other discussions in which this procedure has been followed without any report of ill effects. If you can't satisfy yourself that the instructions are safe, don't follow them. Ask for other options.
    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.
    4. 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.
    5. 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.
    6. 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.

    Copy the selected text to the Clipboard by pressing the key combination command-C.
    7. 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.
    8. If you see an error message in the Terminal window such as "syntax error," enter
    exec bash
    and press return. Then paste the script again.
    9. 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.
    10. 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 the results. No harm will be done.
    11. 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.
    12. When you post the results, you might see the message, "You have included content in your post that is not permitted." It means that the forum software has misidentified something in the post as a violation of the rules. If that happens, please post the test results on Pastebin, then post a link here to the page you created.
    Note: 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.

  • Format iMac - Late 2009

    I want to format my iMac (Late 2009) and i am now on Yosemite 10.10.1
    and originally my iMac came with Snow Leopard ...
    The original DVD for OS X installation doesn't work in the DVD drive in the iMac, each time i load it in , it makes some sounds and then ejected automatically.
    i Copied the content of this DVD on an external Flash drive and external HDD as well but it couldnt work.
    Any idea how to force format it ?
    and also am i able to install the Yosemite directly after formatting it or i have to install several OS X in sequence starting with Snow Leopard till i reach Yosemite ?
    Thank you very much for your time.

    Do a backup. Boot to the Recovery Volume (command - R on a restart or hold down the option key during a restart and select Recovery Volume). Run Disk Utility Verify/Repair and Repair Permissions until you get no errors.  Reformat the drive Mac OS Extended (Journaled), then click the Option button and select GUID. Then re-install the OS.

  • IMac late 2009 - beach ball of death

    My iMac is hanging a ridiculous amount - Every 30 seconds or so, no matter how few applications are running, I get the beach ball of death. It'll typically stall for a minute or more. Ugh.
    I upgraded the RAM to see if that would fix the problem, and it didn't (the computer still hangs when available RAM is in excess of 10GB). I've run the Apple Hardware Test, and there were no problems reported. I've run virus scans, and there were no problems reported. I've upgraded the machine to OSX Lion, and have all of my software updated to current versions.
    Please let me know if you have any ideas for a solution!
    System specs:
    iMac Late 2009, 21.5 inch
    Processor  3.06 GHz Intel Core 2 Duo
    Memory  12 GB 1067 MHz DDR3
    Graphics  ATI Radeon HD 4670 256 MB
    Software  Mac OS X Lion 10.7.2 (11C74)
    Thanks,
    Mike

    Yes... took it back to Mac Store who sent it to their depot who did a deeper scan and it was a failing harddrive.  Thank goodness for Time Machine and having backups... I am not as stressed as I would have been.  However, they reinstalled it with Snow Leopard instead of my purchased Mountain Lion.  When I brought it home I imported from Time Machine.  But another issue reared its head and fought with its password issues (seriously, hours of work there) only to find that I could not upgrade from SL to ML on my disc.  I did a check for software update from the Apple Icon (no Apple Store in SL) and it downloaded 1.6 GB of 5 updates (what appears to be the Java and others that are making the rounds currently).  When this installed I was unable to log in at all, unable to get past the login screen, with some heavy duty serious lag and blue screens.  So I am BACK at the Mac Store and having them do a complete wipe (again) and installation of Mountail Lion this time.  In theory I should be able to take my machine with a new harddrive, Mountain Lion installed, back home and import form Time Machine. 
    Preach it from the rooftops and mountains... buy an external hard drive and install Time Machine.  Seriously!  Do it now!  I am very happy that I finally, after a year, got around to doing this in time.

  • Should I Plug the iMac (Late 2009 i7) Directly to the AVR or AVR- Supressor -iMac

    Hi. I have an Omni AVR 1000w with delay switch, built-in fan when it overheats, input and output indicators, servo motor, will turn off if it's overloaded, circuit breaker and fuse. It's the best AVR I can get (no blackouts here at the meantime and APC is expensive). I also have a good Belkin surge supressor which has 8 outlets. The iMac late 2009 i7 can be plugged at the back without any adapter.
    Should I plug the iMac (which has a huge 3 prong plug) directly to the AVR to give it better, more quality current coz' it's a shorter distance to the iMac or should I plug the surge supressor to the AVR then plug the iMac to the surge supressor which has a cord length of around 2.3m or about 7 to 8 feet? Which one will give a more quality current for the iMac. Will the AVR with all it's features protect it from lighting even if it's not connected to the surge suppressor? The belkin has two external drives and two desktop electric fans and a battery charger plugged-in usually. Will connecting it to the supressor give less quality current coz' electricity has to trable farther?
    Thank you in advance.
    Gbu.

    Hi. Thanks for the reply. No UPS here yet (no budget the 500w one is too expensive). I only have an AVR and the surge supressor. Is the AVR (I think it's called line conditioner/line regulator in other countries) a surge supressor also?

  • I can't seem to get my iMac (late 2009 model) into automatic sleep mode.  If I manually put it into sleep I don't have any issues.  I used to solve the issue by running "PleaseSleep" application but that doesn't work anymore since Lion.

    I can't seem to get my iMac (late 2009 model) into automatic sleep mode.  If I manually put it into sleep I don't have any issues.
    I used to solve the issue by running "PleaseSleep" application but that doesn't work anymore since Lion. I now want to fix the underlying problem.
    I'm not running any weird background processes and in my energy saver settings I've tagged "put the hard disk to sleep when possible:, "allow power button to put computer to sleep" and "automatically reduce brigthness". All pretty standard.
    Is there anyone who can give me some pointers ?

    Today I solved the same problem for my iMac running Snow Leopard. See https://discussions.apple.com/thread/3008791#15947706. The method may help you, too.
    For me it was the DynDNS Updater preventing my iMac from automatically entering sleep mode.
    To my knowledge the cause of this sleep problem can only be a peripheral device or a process. So I suggest to first unplug all peripherals and test whether that's the cause. If not, I suggest to terminate one process after another and to test automatic entering of sleep mode after each. Start with user processes; continue with system process if necessary.
    At least that's the way I found the offending process. Fortunately, I was able to change the configuration of that process to allow again automatic entering of sleep mode.
    Good luck!
