EFI update on 24" White iMac.

the installation was successful but the computer wakes up from sleep and turns it on automatically. What can I do?

Bumping due to the recurrence of the issue...
I guess I somehow solved the problem by booting from a Windows CD from the option-boot screen. It then gave me the text that told me to press any key to boot from CD. I pressed nothing and it booted from my Windows partition just fine. I figured it was some kind of MBR issue.
Well, that's not the case, because now I'm getting the black screen no matter what. The only way I can use Windows is through VMWare, which gives me very little in the way of 3D acceleration. So now I'm stuck without a solution. Apple said that they're working on a knowledge base article for this kind of thing, but that was a while ago and I have seen nothing. Thanks for the garbage quality control, Apple. You can't fix a problem that has been known for over a year!

  • EFI update 1.8 on iMac 21 mid-2010

    I have a problem updating my EFI.
    My computer is an iMac model 11,2 which has Boot ROM version IM112.0057.B01 and SMC Version 1.64f5.
    I wanted to carry out an internet hardware test as my computer is giving me some trouble however it told me that my computer did not support it.
    I read through support groups and I understood that my EFI is outdated so I proceeded to try to upgrade it.
    I proceeded to download the EFI Update 1.8 as per website however, when I try to install it, I get this Alert - "This software is not supported on your system.".
    What does this mean? Can I update the EFI? Can I do an internet hardware test from my computer?
    Thanks for all your help guys!
    Model Name: iMa

    Hey Cesco70,
    The test I believe you are thinking of is known as Apple Hardware Text. to implement it, use the steps in this article -

    Thanks for using Apple Support Communities.
    Be well,

  • IMac EFI update problems

    My Mid 2011 iMac 27" i7 will no longer start after the latest EFI update.
    I decided to perform some system updated on my iMac and after installing 10.7.3, I rechecked and it found the EFI update and one other update. They were both pretty small (the largest was 3.6MB), so I decided to proceed prior to getting back to business with my system.
    After downloading the updates (took about 5 seconds), the machine proceeded to restart. There was a loud beep prior to the system restart chime after which it went to the grey-white apple startup screen with the spinning wheel.
    And it stayed there.
    After 35 minutes with no discernable progress, I decided something must be wrong. This system normally takes about 30 seconds to boot from a cold state (it's running on an OWC SSD) or maybe a minute after updates. So I held the power button to reboot. But it keeps going to the same state. I tried to reboot to a different internal drive holding the option key, but the same thing happens.
    System Specs:
    iMac 27" i7 3.4 Ghz (mid 2011) 12G Ram
    Internal 1TB Apple HD
    Internal OWC SSD 240G (main startup drive)
    Here are my questions:
    1. How do I recover from this?
    2. Is anyone else running into this problem?
    3. How long do the EFI updates normally take?
    4. Shouldn't there be some sort of "progress bar" to indicate something is going on during this process? Or, if not, then perhaps a "WARNING!! This process will take up to two hours, during which you will receive no discernable feedback. Do not interrupt the process until more than 24 hours have passed with the spinning ball."
    Thanks for your help.

    P.S. I think this is my last iMac EFI update. After my last iMac received an EFI update (2009 model 24" iMac), it became ultra-flakey and started corrupting HD's. It never worked the same after that. This machine was working PERFECTLY before the update.

    I don't have the link to that thread, but here is how to do it:
    To reset the SMC:
    Shut down your system.
    Unplug all the accessories from the system
    Unplug the power cord from the iMac and leave it unplugged for at least 15 seconds.
    Reconnect the power cord. Wait another fifteen seconds and restart the computer.
    To Reset the PRAM:
    On startup, hold down these keys at the same time (must start before the grey screen comes up): command option  p  r
    Hope that helps.

  • IMac EFI Update 1.3 will not install

    Hello,
    24'' Intel iMac (about 2 months old) running 10.5.2.
    Auto updater tried to apply the iMac EFI Update 1.3, but failed. So I went to apple support site, downloaded a .dmg, ran the installer, but got the same result. in both cases:
    get the iMac EFI Update 1.3 window that contains instructions. hit shutdown. hit the hardware start button, get gong, machine starts to boot, something briefly flashes on the screen (probably the updater progress indicator, hard to tell) and then machine reboots itself. after boot completes, the iMac EFI Update 1.3 applications pops up again in the exact same state as before-- there is no indication of success. SystemProfiler shows that boot ROM is still the old version.
    Rinse, repeat with no sign of progress.
    Any insights much appreciated.
    thanks,
    Joe

    "...hit the hardware start button, get gong, machine starts to boot, something briefly flashes on the screen"
    Hi Bob, you have to hold down the start button(5-10secs) until you hear a long tone. Then let go and everything is ok.
    You'll also see the progress bar install the update, that is what the brief flash was but because the button wasn't held for a few seconds, it didn't take.

  • EFI Update Lost The Speakers?

    I'm on a brand new iMac 24". I ran System Update and now all the software is up to date. Part of that, apparently, was an EFI updater, which I also ran. After the EFI updater, the iMac no longer "sees" any internal speakers.
    Here's a screen shot: http://i14.tinypic.com/6hgi0dc.png
    Any ideas?
    Intel iMac 2.16GHz   Mac OS X (10.4.10)  

    Open GarageBand and see what happens.
    Also after all these updates did you go to Apps/Utilities/Disk Utility/First Aid and Repair Disk Permissions on your boot volume?

  • EFI update went well.  Am I crazy or do things seem snappier

    I just updated my iMac with the EFI update. Very smooth. Subjectively, the machie seems much more responsive and quick. Is this just me or have others noticed what appears to be this increase in responsiveness. For example, applications just seem to load much more quickly.
    Steve

    Hi Steve,
    You're not crazy AFAIK . I did the EFI update yesterday and, after a slight glitch which is described in this thread,
    http://discussions.apple.com/thread.jspa?threadID=1153464&tstart=15
    I was surprized by a 20 second bootup this morning. 20 seconds! It used to take about 25 to 30 seconds prior to the update. Hope this continues. And yes, everything does seem snappier as you report.

  • Netboot Issue - White Imac to 2007 AL Imac

    Hi
    We have just purchased 20 Mid 2007 Aluminium iMac's to add to our existing network. - The one i have taken out of the box was pre-installed with 10.4.11 with a Leopard Upgrade Disk inside (said that Leopard is not installed on the machine but can be upgraded by use of this disc).
    We have a 10.4.10 Netboot image (built on a 17" 2006 White Intel iMac) on our XServe that I have tried to restore onto one of the new Aluminium Imac's.
    The actual netboot operation worked fine and the operating system booted up on the new Aluminium Imac - but then i have found;
    a) the onboard LAN port is greyed out and cant be configured
    b) the isight camera does not work
    c) the sound does not work
    I downloaded the 10.4.11 combo updater and ran that on the machine hoping that it would replace drivers, etc - no chance.
    Is there a way i can get the specific drivers for this hardware, as I dont want to have to install all of the programs and settings that we have for our network. then have to clone it 20 times.
    Or is there a way i can remove the settings for the missing items (network, isight, sound) from the computer prefs and get them rebuilt on system startup?
    Frustrated that Apple support has been less than forthcomming, with the reply of
    "upgrade to Leopard" - Upgrading to Leopard is not an option.
    Not understanding the problem which i was facing.
    I might have to return the 20 and just get hold of 20 of the White Imac's - which are on sale from our reseller.

    Thank you so much for your information.  I have been using a Seagate GoFlex portable drive as my back up disc with TimeMachine on my iMac.  The AirPort Time Capsule is arriving tomorrow with my new iMac.  My question to you is this:  Will it be easier to wait till tomorrow, set up my AirPort Time Capsule and back up my old iMac to it and then use it with the Startup Assistant to transfer my stuff or will it be easier just to use my GoFlex back up disc?  I have had some issues in the last year where Time Machine send me a message that the (daily) back up failed because the file got corrupted and I have been unable to fix it so that I have to reformat the disc and back up everything I have.  Just an FYI, I don't have a huge amount of stuff on my iMac even if is almost 7 years old....I have 900 GB out of 1TB available.  This is one of the reasons I felt it's time to replace my iMac.
    Right now I have a clean encrypted back up on the GoFlex but I don't want to transfer anything I shouldn't to my new iMac.  Please advice and thank you.

  • Built-In iSight NOT RECOGNIZED after EFI Update 1.1

    After updating to EFI 1.1 on my iMac 20 Inch (2,16Ghz) the built-in iSight-Cam is not
    working anymore. It´s not showing up in the system profiler > USB Devices.
    I bought the iMac last week, switched it on, the cam took a picture on the user account creation,
    I applied the EFI-Update and OSX 10.4.8. After that the cam was gone.
    I tried everything from resetting SMC, PRAM to reinstalling Combo-Update 10.4.8 ... NOTHING helped !
    Any ideas or solutions ???
    P.S.: Sorry for my crappy English, I´m writing from Germany !

    Here´s a report from MacFixIt.com about this problem:
    http://www.macfixit.com/article.php?story=20061211231332862
    Built-in iSight not recognized Some users have reported loss of their built-in iSights after applying the iMac EFI Firmware Update 1.1. In some cases, this issue can be resolved by resetting the SMC (system management controller) using this process:
    1. From the Apple menu, choose Shut Down (or if the computer is not responding, hold the power button until it turns off).
    2. Unplug all cables from the computer, including the power cord and any display cables.
    3. Wait at least 15 seconds.
    4. Plug the power cord back in, making sure the power button is not being pressed at the time. Then reconnect your keyboard and mouse to the computer.
    5. Press the power button on the back to start up your computer.
    Resetting PRAM can solve a variety of issues As mentioned in our coverage of recent EFI Firmware updates issued for other Macs, a number of potentially serious issues apparent after applying this EFI Firmware Update can be resolved by simply resetting PRAM/NVRAM via the following process:
    Shut down your Mac, then start it back up while immediately holding the following keys: Command, Option, P and R. Hold the keys down until the computer restarts and you hear the startup sound for the third time.
    This workaround is a good first course of action before exploring more complex fixes. It should also be attempted if your system cannot properly startup after applying the update.

  • Snow Leopard on a 1.83 White iMac Core Duo w/ GMA 950 Integrated Graphics?

    Hi. My parent's computer is an older, white iMac with a GMA 950 integrated graphics. Currently it's running Tiger and it runs very well.
    However, I am in town for a short bit and was thinking about updating their system while I'm here. Does the iMac 1.83 with integrated graphics run Snow Leopard very well? Or should I just leave Tiger on it?

    Anyone with a 1.83 iMac Core Duo with integrated graphics (NOT the ATX 128 mb graphics) running Snow Leopard?

  • White Imac and Leopard

    Hi,
    My white Imac has Tiger, should I upgrade to Leopard?
    what are the known issues?
    How is Leopard working with Adobe CS3 applications?
    Do they run better on Leopard?
    thanks.

    First ask yourself is this your primary work machine? If work flow is your number one priority you probably won't want to make any changes that might interrupt your work flow. However if you have the time to install the upgrade without it impacting your business then go for it. I am running Leopard and have not found any problems that I couldn't work through and the new features are great. I have heard that there are some issue with CS3 in Leopard that are awaiting updates to resolve but I do not know what they are as CS3 runs great for me. Then again CS3 is not of my main applications that I use. You might search around and find out what exact issue CS3 might have in Leopard.
    If you are concerned and have an external drive, you could clone your system as it is before you upgrade to Leopard just in case something goes wrong you could restore your system to how it was. Otherwise I recommend doing an Archive and Install. When you boot up to the Leopard install disk and get to the part where you select the drive to install Leopard on, before you click install, click on the Options button. There change it from Upgrade to Archive and Install. Also put a check mark in the box that says Preserve Network and User data. Doing this will ensure that you get a clean install of the new system but it will migrate all of your applications and user settings for you.
    BTW How much RAM do you have in your system? CS3 uses a lot in general but Leopard also tends to use more RAM than Tiger does. This is a good thing.

  • Blue/White iMAc G3 233mhz/32mg 512cache

    have a blue /white iMac G3 and when i turn it on a flashing and mac folder began flashing. i have tried everything in resetting nvram holding command option and p and r keys also of key . I remover the old battery it had no voltage rest cuda button same flashing Question mark and mac face. I do not have any of the original cds, if anyone has any would appricate a copy of these cds if all possible unless someone has any other sugguestions NEED HELP PLEASE. I have a ImacG5 and tried loading the operating disc to see if it would boot up no luck

    Hi, abelmichael -
    The information Kappy gave you in your other thread is correct - the flashing icons when you try to boot indicate the machine can not find a valid OS from which to boot.
    That can be caused by a weak or dead internal battery. You said you checked the battery, and it was dead - you did not mention whther you had replaced it. If you have not yet replaced it with a fresh one, do so before going any further with trouble-shooting. Reset the CUDA again when replacing the battery.
    If that machine had had OSX on it previously, then its firmware has probably been updated, and you can install OSX on it again.
    If it did not have OSX on it previously, and if you are not sure that the firmware on it has been updated, do not try to install OSX on it. IN the case of early iMacs, just booting the machine to OSX when the firmware has not been updated can result in loss of video.
    You can get any firmware update needed for a CRT iMac from here -
    Article #58174 - iMac: When to Install Available Updaters
    The forum best suited for problems with your iMac 233MHz model would be the "Using your iMac (CRT)" forum, here -

  • New update tonight killed my iMac! Ugh!

    Computer has been working fine, Apple update came up and pointed out three new updates for the new iMac including general fixes and keyboard enhancements.
    Did them and restart..now the white screen of death! Did hard boots, power off boots..unplugged everything and booted. Still white screen of death.
    Is this the Mac answer to windows blue screen of death?
    This is highly annoying! Any ideas?
    TIA

    I have bad memory (in my head, not computer ) but:
    These updates - it was the updates from last week (32MB for keyboard and such)???
    Because I installed it on Friday and everything works fine on my new iMac 24" so far.
    Yesterday I installed AirportBase Update and again... no problems after.
    And I haven't seen any other updates yesterday.

  • Interruppting EFI Update

    What happens when you interrupt the EFI update?
    I was in the middle of running my EFI update. Now I can't seem to get my Mac running. I tried all the troubleshooting tips that was in the manual. I also refered to the update instructions again to try and restart the update. Now my LED light blinks from dim to bright.
    Is there something that I can do or would have to return my laptop?

    Welcome to Apple Discussions, Shugah Shane.
    EFI updates should not be interrupted. But you know that now
    Did you read this support topic also? You may be able to create a restore disk w/o bringing your Mac in for repair.

  • Performance reduced under Bootcamp after EFI update on Macbook Pro Retina

    after i upgraded EFI on my retina macbook pro the proformence reduced to unusable. under heavy load under bootcamp windows7. the cpu clock drops and as well as cpu clock. this is the screen shot of gpu clock monitoring from windows u can see the gpu clock is running at 270Mhz at most of the time and trying to be back to 725Mhz(yea, not 900Mhz!) when im running a graphic benchmark at same time cpu will run about 1.1Ghz as well. i noticed that it will run 10-20sec normally then CPU and GPU clock will start dropping. It's almost like speedstep is programmed backwards. My CPU is constantly running at 3.1-3.2GHz, and then as soon as a game loads, it drops to 1.2GHz. I've lost track of how many times I reset the SMC  reseting SMC PRAM, reinstalling windows using Bootcamp or even erease the entire drive and start over from network recovery MacOS did not solve this problem. so all the recent games like COD MW3, Starcraft II, BF3,or D3 will only run about about 10 fps as i was playing them with no ploblem before the EFI update.
    this is killing me! please help.
    im in NY, in this season i dont think is the overheating problem. when i check the temperature, it stays about 80C (fans will run about 4k rpm). but some time heavy loaded Mac OS cpu is about 90 degree but only with 3k rpm fan kicked in.
    i did search online, seems that some other people have the same problem with rMBP or MBA 2012.
    anyone knows if i take my macbook pro to the store, will those people work at genuines bar help me with this "windows" problem?
    thanks!

    Hey Shadowyani, please take a time and fill a bug report at http://developer.apple.com/bugreporter/ . The machine is useless for me as it is now because I develop and use very GPU/CPU demanding scientific applications, after the update my realtime applications are completely useless as they drop from something like 25fps to 9 fps even on Mac OS X (no SMC reset fixed the issue). In bootcamp the situation is worse, my software runs at 4 fps and gaming turns to be impossible to play as well.
    Please let Apple know about the problem, fill a bug report, even if SMC reset once in a while fixed the issue for you (this is not a common behaviour and must be fixed). We paid the price for cutting edge technology.
    Apple shall not do a downgrade of the system after few weeks, remember that most of reviews and benchmarks were done BEFORE the EFI Update, so people are being fooled by Apple in this sense.
