24" iMac freezes after failed 1.4 EFI Firmware update

After scouring the internets I'm hoping you guys could help me.
I was having trouble with boot camp waking from sleep which was supposedly cured by installing the 1.4 EFI Firmware update. While I was installing the firmware upgrade the computer crashed... when it rebooted it took (and continues to take) about 10minutes to boot. Aside from random freezing (more frequent under heavy use), my firewire ports are dead.
I've tried re-installing the firmware but the it say this computer does not need this update.
I've also tried everything outlined in the article: [URL="http://reviews.cnet.com/8301-13727_7-10329023-263.html"]Can't install EFI Firmware Update? Check partition scheme; disconnect peripherals[/URL]
"So the procedure would be: Use Disk Utility to Get Info on your internal drive (the whole thing, not just a partition of it) and thus check the partitioning scheme of your internal drive. If it isn't GUID, then you could clone to an external drive, boot from the external drive or from your installer DVD, repartition the internal drive as GUID, clone back from the external drive to the internal drive, boot up from the internal drive, and perform the firmware update."
I'm at a loss... any ideas has anyone else had this problem?

Please give more information , what version of windows are you try to use via boot camp?.
(in the windows installation process the Mac Os Partition will be there if you put the windows in the wrong partition automatically you are formatting and installing windows on the Mac Os partition.
Hold "Option" for 7 seconds as you hit the power button .
If everything is correct you can choose between Mac or Windows OS for the start up, select the mac OS
If everything is good still you can use your MAC OS normally till you get a fix .
When booting in windows is normally to the mac not recognize the firewire ports, and depending of the version of the windows in your iMac takes about 5 minutes or more for the Boot .
Please note Not all the "intel macs" are compatible with windows 7 ....
Please give more information , but is look like your firmware is OK , (already you try to re-install it)
Take care with disk utility operation, if you can back up your data and reinstall everything again it may help . (a external hard drive and Time machine can help you a lot) .
If you are near by a Apple store , the genius bar guys can give you more details and the proper help ..you can bring the iMac there .

  • Slow Booting time after installing MacBook Pro EFI Firmware Update 2.0 on 13 Inches Mac 2010 model

    I'm experiencing a slow boot time after my computer installed a MacBook Pro EFI Firmware Update 2.0 itself on 13 Inches 2010 model, how to downgrade or fix it?
    My computer is starting 2 times slower then it should be, why Apple done this to me?
    Please help who really know somthing about Macs.

    I have the same problem, especially when I open my laptop from sleep.  It takes at least 2 minutes for the computer Internet connection to work.
    Never had that problem prior to the last firmware update 2.7.
    Is there a way to revert back to 2.6?

  • My imac freezes after 5 minutes of use

    my imac freezes after 5 minutes of use, that's including after i reboot.  is there something that i'm not doning because it's freezing on all my programs.

    Please read this whole message before doing anything.
    This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
    The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, or by a peripheral device. 
    Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Ask for further instructions.
    Safe mode is much slower to boot and run than normal, and some things won’t work at all, including Wi-Fi on certain iMacs. The next normal boot may also be somewhat slow.
    The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin. Test while in safe mode. Same problem? After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.

  • HDD clicking after EFI Firmware Update 2.7

    After I did the EFI firmware 2.7 update and the my macbook pro restarted, I noticed that I started to hear a clicking noise from my laptop. At first, I thought it was a normal sound that I may have not heard before but I checked my other laptops and they aren't making any noise close to this. The other two laptops I checked were also early 2011 models, one 13" and the other is 15".
    Here is the recording of the sound.
    http://dl.dropbox.com/u/108564/iPhone/Memo.m4a
    There is some background noise but that clicking sound is the sound I hear. This is recorded with my 4S with the mic hovering around the palm rest and trackpad. I also noticed that when I tilt the laptop, I can hear a grinding sound. I tried to replicate this grinding noise on my other MBPs but I can't replicate it.
    What is the best option for me? If I take it to Apple, would they actually be able to replace it for me or resolve the issue? I don't want to waste my time driving 45 minutes to Apple just so they can say it's "normal". Has anyone had this issue before and taken it to Apple?

    Pretty nasty, sounds quite regular. Drives don't make that sound normally, sounds defective.
    What is your machine specs, opeating system version etc.?
    If your drive is grinding, that's a sign it's going to die soon, so you need to backup immediatly.
    EFI 2.7 might not be the sole cause, especially if others don't come forward and report the same issue, but might have attributed to something pre-existing.
    There has been a unusually high number of issues with the latest EFI firmware updates, why I don't know.
    Perform a hardware check, rule out anything else.

    You might have a warranty call if the drive is failing.

  • After installing an SSD into my optical bay, I've found out I need EFI Firmware Update 2.2. I can only find 2.3 which is not supported on my Mac. What can I do?

    After installing an SSD into my optical bay, I've found out I need EFI Firmware Update 2.2. I can only find 2.3 which is not supported on my Mac. What can I do?

    You do not want EFI 2.2, it bricked many 2011 MacBook Pro machines.
    EFI 2.3 is the fix. Software Update should install it if you need it, but it goes to the boot drive as that's where the hidden EFI resides.
    Check out this link of machines and their EFI versions
    https://support.apple.com/kb/HT1237
    Also if your SSD should be in the hard drive bay as it makes a better boot/applicaitions drive, not a good storage drive as it wears out with repeated use and is not "scrubbable" like a regular hard drive
    The hard drive should be in the optical bay and used as a storage drive, you have things all messed up inside your machine, Apple doesn't support or expect the optical drive to be used as such to begin with, then as a boot drive is just asking for trouble. So use the optical bay as storage and not as a boot bay.
    Also you can't install OS X or Windows or use a Firmware restore disk because it only works from a internal optical drive, which you have removed.
    https://support.apple.com/kb/HT2213
    You need to learn all about cloning etc., as you have no other means to boot the machine.

  • Late 2011 MacBook Pro running Mountain Lion with app: "iMac EFI Firmware update"

    I have an app on my MacBook Pro late 2011 model, by the name "iMac EFI Firmware update" that my computer says is useless... can I uninstall it using CleanMyMac without corrupting my OS Mountain Lion or simply dragging it to the garbage?

    You can delete it. Just drag it to the Trash and this installer will be removed. As you have already installed this update, you don't need the installer anymore on the hard drive

  • Installed iMac EFI Firmware Update 1.1 - now programs keep crashing

    Hi,
    I installed the firmware update as recommended by apple and now I find that most programs crash on a regular basis. In particular, MS Office (Had this installed before the firmware and it worked perfectly) and iTunes.
    Can I back out the firmware update?

    1) Quit all applications
    2) Click Shut Down in the iMac EFI Firmware update window and wait for your computer to shut down
    3)Press and hold the power button until you hear a long tone,then release the power button
    A status bar indicates the progress of the update
    Important: Do not interrupt the update
    Your computer restarts automatically when the update is completed and opens the iMac EFI Firmware update.
    Click OK if the firmware is up to date
    If these instructiona appear on your screen again repeat steps 2,3 and 4
    Hope this helps - I had the same trouble initially!

  • Software Update Failed - MacBook EFI Firmware Update 1.4

    Superdrive Firmware Update 3.0 fails each time, /Applications/Utilities/SuperDrive Update.app asks me to quit all apps and try again which I did but of no help. I also retried with a reboot. Help!

    What are we talking about: EFI firmware update or superdrive firmware update? What generation of MB do you have? Was any update detected by Software Update? How does it fail? is there any message? hos do you proceed?

  • /Applications/Utilities/MacBook EFI Firmware Update... Missing?!

    Hey folks, I've done a search of the forums but to no avail. A Google search has turned up precisely nothing like what I'm experiencing here. I have no idea if it's normal or if my wee 'Book's playing up.
    Basically, in checking my RSS feeds, I was informed of the release of a new firmware update for C2D MacBooks, available via Software Update. I ran Software Update and... nothing. I decided I'd check in Apps/Utilities and use the EFI Updater to manually update my computer's firmware, but the utility seems to be missing altogether. Anyone else experienced this, or have any idea what's going on? It used to be there, and I can't really think of anything that might have made if go 'poof!'
    I realise this isn't exactly a major issue, but I can't say I'm at ease with the disappearance of bits and bobs from my Mac.
    Any info would be greatly appreciated.
    Gray.

    Well if it's any consolation Leopard seems to have thrown over the generic EFI Updater that used to fly standby on my MacBook, but apparently left a new one or left the newer one that may well have been abandoned on my iMac after that rather disconcerting task was deemed necessary a few months prior.
    Seems that the updater app comes with the new image whenever and however the time to update becomes a pressing concern so maybe space saving has something to do with the policy.
    There does seem to be a colorful spectrum of issues surrounding the ins and outs of EFI firmware notifications and techniques from platform version to another but
    http://docs.info.apple.com/article.html?artnum=303364
    clears up any confusion pretty much and
    http://support.apple.com/kb/HT1237
    seems to nail down which chicken goes in which pot. Nonetheless I picked up a bum steer at Apple Support Downloads yesterday over that shiny new "iMac EFI Firmware Update 1.3" delightfulness recently trotted out as better than sliced bread for something they refer to as an iMac!
    So joyful I was at the thrill of being ahead of the line I I dropped everything, downloaded and installed it, but only to be politely informed that my unit was lacking any of the discomforts it was intended to relieve. It's nice to get something for nothing but I kind of wish I could say the same :P

  • EFI firmware update 1.4 killed my ethernet connection

    Trying to set up my sister's new 20" iMac.
    It came preinstalled with 10.5.6. We hooked it up to her cable modem with an ethernet cable, it got a DHCP'd IP address, I immediately ran software update and it downloaded a slew of stuff. After the initial update and restart, it went into the firmware update procedure for EFI Firmware Update 1.4. After the update we got the expected loud beep and restart, but now the ethernet connection is dead.
    The computer claims the ethernet cable is not plugged in - network diagnostics says it can't do anything - to contact our network admin.
    I tried another cable, I tried recreating the "Ethernet" connection in Sys Prefs->Network and also tried creating a new connection with ethernet but ethernet remains stone dead.
    Anyone see this before?
    Jeez, this thing only worked for like an hour :-/

    Solved:
    Tried 2 ethernet cables and all ports on the router with no luck.
    Reset the PRAM with no luck.
    Tried another router port - success!
    Some experimenting reveals that the router port the computer was plugged into at the time of the EFI 1.4 update is now dead. It was working fine up til the firmware update but now won't work with any combination of cables or computers.
    The iMac connects fine over ethernet to all of the other router ports with all 3 cables we have here.
    Weird. I cant imagine that the firmware update somehow killed the ethernet port on the router. Timing sure is strange tho.

  • EFI Firmware Update 1.2. won't install

    I can't find exactly my problem but some threads are close. I keep getting software updates for EFI Firmware Update 1.2.
    I shut down, then startup holding on-button until it flashes, release, buzz buzz, chime, then very briefly the apple logo and status bar, then gone, buzz buzz, chime and restart. After everything loads, there is the update window with install instructions, telling me to repeat if I see them, to no avail (tried several times over several weeks). My HD appears to be correctly partitioned, with this boot ROM: IM51.0090.B03 which would seem to indicate the update has not happened. I have unplugged all my peripherals (printer, zip drive) but not DSL modem.
    any ideas?
    thanks in advance
    craig

    I would delete the firmware updater that is in your Utilities folder and check your account settings(System Preferences/Accounts/Login Items) to see if it has been added to your login items. If so then remove. Re-run your software update and see if the Firmware update shows up again. If so then download and try again. According to Apple your BootROM should be IM51.0090.B09 after the update.

  • EFI Firmware update 1.4 was not successful, no progress bar

    I have a MacBook Pro 2.16 Core 2 (MBP22.00A5.B02). Software update prompts me to download and update the Firmware 1.4 udpate. After following the instructuions, shutting down the computer, and restarting holding down the power button, I hear the beeps but nothing comes up but a blank (grey/white) screen. After several minutes (like 10) it restarts and the updater returns and shows not successful.

    Hi macinfrance!
    I installed the EFI Firmware update successfully on my computer.
    It seems to me that your list of nvram is lacking an entry telling your bootloader (boor.efi) exists on your normal harddrive partition.
    I suggest the following (i am not quite sure if it will work):
    1. Go to the system preferences and select the startdisk fane. Then, be sure to select your system harddrive.
    2. Then restart your computer.
    3. Make a restore CD in case something goes wrong (instructions at: http://www.apple.com/support/downloads/firmwarerestorationcd14.html )
    4. Try the firmware update again.
    When i type nvram i get the following contents:

  • MacBook Pro EFI Firmware Update 2.0 will not install.

    Hi
    The latest MacBook Pro EFI Firmware Update 2.0 will not install.
    It runs and I restart my Mac but when I search for more updates it appears as a required update again.
    Anyone know why this may be?

    I had the same problem today. I called Apple support who transferred me to second level support and no resolution. I decided to try a combination of the items I have seen below.
    I restarted my computer. I went to apple support download and downloaded the software EFI firmware update 2.0 by typing in search window. I made sure the power cord was pulled into the wall and the laptop had a FULL charge. I installed the update and the computer restarted.
    I went to check the software update window after the update and restart completed and SUCCESSFUL.
    I do not know why the Genius Bar or the second level support could not resolve my issues but, by me reading information here I hope at least this issue is resolved.
    Thanks ALL.......... Happy Mac ing
