IMac 27 screen went blank installing snow leopard

My iMac 24 screen went blank installing snow leopard. Should I wait? I wish this **** machine ha a HDD light like a PC.

You can attempt to reset the PRAM in the machine, but it looks as though there's a hardware problem. It's actually kind of difficult to determine if it's the graphics hardware or the mainboard, but neither are really servicable. You'll want to take it to get serviced.

    Snow Leopard cannot run on a PPC G5 Mac as it requires an Intel processor. Please confirm what Mac you have.

  • IMac i7 need to install snow leopard NOT Lion - Will it allow the install of 10.6?

    I have a bit of a quirk to deal with, a client has a Snow Leopard Network but just recently had a replacement iMac i7 delivered for a previous box from earlier in the year. The IT Contractor is stating that the machine can only take Lion and will not install Snow Leopard. The problem is there is some FileMaker issues that have come up with some deep level custom functions that have exposed a critical problem and the machine needs to run Snow Leopard. This would be until the work around is developed for the software solution or FMI comes out with the next version of FileMaker resolving the issue.
    Is the IT Contract full of it ? If not is there a way to force the iMac i7 to accept a Snow Leopard installation ?

    For years Macs have not be able to run earlier versions of OS X than they originally shipped with so this is nothing new. It also makes a lot of sense when you think of it, one of the reasons Mac's run so well is the software and hardware are optimized to run well together. Attempting to install an earlier version of OS X than what the machine was designed for is technically possible but it also comes with significant risks because you're then dealing with a system that wasn't designed to run well together...in other words you're emulating the MS Windows world.  While there can be some temporary inconvenience as you're experiencing in this case  Apple makes these decisions for a reason. While not always obvious to we end users but there are good reasons none the less.

  • Can't install Snow Leopard on iMac

    Heya everyone. Alright, pretty much I had no problems with snow Leopard for a while until it started not being able to open a few files, I quickly restarted the computer, only to find the mac had stayed at the loading screen. I installed Snow Leopard again, that seemed to work and everything was still there. It crashed a second time 2 weeks later, I accidently put in the Leopard CD instead of Snow Leopard, and restarted the mac before it could confirm installation. Unfortunately i was too late, and tried using the snow leopard CD and didn't work
    Shortly after i just went with installing leopard. it had made a file with all my old files, but all the applications were corrupted and had to be deleted and had to start my apps from scratch on Leopard. Now every time I try install Snow Leopard it won't let me from the desktop, and when i try doing it from restarting the mac it won't even get off the calculation for how long the installation is meant to last. I've tried to go to disk utility and verify and repair the CD and the hard drive, but nothing seems to be working!
    I REALLY want Snow Leopard back, but it won't let me :S Can anyone help me at all?!
    Thanks guys. o0 Will Ryan 0o

    Your story is a little hard to follow.
    Do you have a backup of your important files?
    Is there anything that would keep you from simply erasing your hard drive and then doing a fresh install of Snow Leopard?
    Good luck.

  • Pre-intel iMac installing Snow Leopard?

    Have been told by Apple that the Serial Number for my pre-Intel iMac enables me to install Snow Leopard (currently running 10.4.11). Is this straightforward or should everything be backed up before the installation? I had previously been led to believe that it wasn't possible to instal SL on this Mac. Confused and needing some clarity. Thanks.

    Snow Leopard requires an Intel Processor.  Here are the specs:
    General requirements
    Mac computer with an Intel processor
    1GB of memory
    5GB of available disk space
    DVD drive for installation
    Some features require a compatible Internet service provider; fees may apply.
    Some features require Apple’s MobileMe service; fees and terms apply.
    Either they were wrong or your system does have an intel processor.  You should be able to determine that with "about this Mac".

  • Midisport Uno stopped working after installing Snow Leopard

    Hi
    I have been happily using the midisport uno USB to connect my Roland PC-200 keyboard to my iMac.
    Yesterday I installed Snow Leopard (I figured it was about time) and while MBox 2 is still fine for audio input, I'm unable to detect any midi signals via my Uno.
    Nothing shows up in the ASM, even though I have re-installed the Uno and downloaded the latest driver for it (v3.4.0 for 64 bit)
    I can see the lights functioning so the keyboard is sending a midi signal, but for some reason my computer cannot detect it. I have tried plugging the USB directly into the iMac (despite the fact that previously it was working fine via a USB hub)
    As a control test, I plugged the Uno and the keyboard into an old Macbook - they worked first time. So the Uno and the keyboard are fine.
    Any help gratefully received!

  • New iMac turns on/loads fine, but trying to install Snow Leopard gives 'bad RAM' 3 beeps + grey screen

    New iMac arrived today, turned on and loaded fine.
    After getting to the desktop, I inserted the Snow Leopard disk and restarted the computer.
    I held alt at startup and selected the Snow Leopard disc from the options.
    The computer proceeded to give me the 'bad RAM' error: grey screen + 3 beeps, over and over.
    So did I get an iMac with bad RAM? Poorly seated RAM?
    Very frustrating, I'm disappointed Apple.

    Good luck: Don't install a version of Mac OS X earlier than what came with your Mac
    Earlier versions of OS X, including the present retail version now sold, contain drivers incompatible with the firmware installed on new Macs. You will get the exact same error code you are observing.
    I'm having a hard time believing it is a RAM problem if the computer works fine in OS Lion but gives the error when installing Snow Leopard.
    This has nothing to do with memory. If you don't believe me run Apple Hardware Test and see for yourself.
    If AHT passes and your iMac boots Lion, Apple will tell you to pound sand.
    As I said earlier,
    A new iMac should have shipped with Lion. Attempting to install an earlier OS version will not work.

  • Screen went blank after iOS7 install

    I was successful in upgrading to iOS7 on my iphone 4s but then while browsing the screen went blank. With a blank screen, I can not turn off - should I reset?

    you are aware that while  Applejack worked great on our PowerMacs, it had to be updated for Intel and also that you would now need versions of anything that are Snow Leopard compatible.
    Seeing it was running or had 10.4.6+ minimum, that could mean that the disk drive is also just as old. Not that it died, I still keep some around for backup and such going back even further.
    But did you ERASE the hard drive with SL DVD before installing? that way works better as there are changes in disk structure and partitions and works better than not doing so, and definitely better than an upgrade in place. Setup Assistant can help immport what you need.
    You might want to clone the system to a new drive anyway now that it does boot. You can do so with the DVD and DU Restore, or with SuperDuper or Carbon Copy Cloner. CCC is no longer 'free"/shareware but has been improved and supports Lion+ much better, and easy to use to selectively copy - like to not move non system, and move those to a data-only drive.
    just some ideas.

  • My 2006 iMac running Snow Leopard won't boot even after erasing and re-installing Snow Leopard (via my MacBookPro), either from the HD or DVD drive.  Can't get it to run Hardware Test.  Disk Utility says disk OK - files are there. What can I do?

    My 2006 iMac running Snow Leopard won't boot even after erasing and re-installing Snow Leopard.   I erased and re-installed by putting the iMac in Target Disk mode and usin my MacBookPro as the host.  But after numerous attempts I still can't get it to boot either from the HD or DVD drive. I just get the white screen after the wheel stops spinning.  I can't get it to run Hardware Test - just get the white screen.  If I use Disk Utility via my MBP it says the disk appears OK. All the Snow Leopad files appear to have been installed. What can I do?

    Perhaps you installed the wrong version OS X onto the iMac, you can't use the disk from another Mac.
    clean the disk.
    If it's not working then use this method to create a bootable 10.6 USB from the iMac machine specific 10.6 disk or the 10.6.3 retail disk on your other Mac, use it to boot the iMac with.

  • Imac 27" - installed Snow Leopard from macbook pro - just get grey apple

    I have a friends imac he bought second hand and it starts okay but the mouse moves but the click is unresponsive. I wiped it via firewire target mode and installed snow leopard.... all that happens is I get as far as the grey apple screen.... I checked again via target and it appears it installed okay. It won't launch into safe mode... kinda stumped

    If you installed Snow Leopard via FireWire target mode on the iMac using the disks that came with your MBP, then that's the problem. First, of course, is the fact that that is illegal. The real technical hurdle, though, is that those gray disks that came with your MBP install a system that works only on your MBP.
    Your friend needs his own Mac OS X install disk. If the machine didn't come with one, he will need to either buy SL retail, or call Apple and request a replacement for the gray disks that shipped with the machine (which contain things not on the SL disk, like bundled software and the [Apple Hardware Test|http://support.apple.com/kb/HT1509] boot system).

  • Colors went DARK after installing Snow Leopard

    Anyone else have this problem? I installed Snow Leopard, everything went smoothly except I noticed my background desktop image was extremely dark. Even the UI is darker, except the dock appears whitewashed, as though the brightness on it was cranked up separately from everything else.
    I tried calibrating a new color profile, but it came out looking pretty much exactly the same as it already is.
    I found a workaround, and I copied everything out of my libraries/colorsync/profiles folder from my Time Machine drive, from before I installed SL. It's much closer to normal now, but much of the UI displays color information incorrectly, like in the dock.
    Does anyone know a real way to fix this problem, without having to rig a temporary solution as I did? Or is this just something we have to wait for an update on?
    My monitor is a Dell 3007WFPHC 30" LCD, if that makes any difference. I've also noticed I have NO software screen brightness/contrast controls anywhere. The keys don't do anything, and I have no sliders in the System Prefs, Display area, like many others seem to.
    Thanks in advance if anyone knows anything about this.

    I can't tell you if "No Display Connected" indicates an error or not. I see the same message on all my Macs, but they all have built-in displays. I think the Display Connector info pertains to external or secondary displays only, but I'm not certain about that. Maybe someone with a similar Mac model will chime in here with a better answer for that.
    Is there anything unusual about your setup? Are you maybe using a graphics card not originally shipped with your Mac? Starting up with the 64-bit kernel? Have you installed any graphics drivers besides what came with the OS?
    Also, have you checked your display manual for anything relevant? I've used various monitors with client's Macs & some have settings that switch off automatic detection of resolution changes, sending display info back to the source, or other things of that nature. If nothing else, see if there is a reset procedure or general mode setting command mentioned. In particular, look for any automatic "smart" settings that aren't so smart. I was recently running a redundant pair of identically configured Mini's with identical, out-of-the-box new LG monitors for a client. The two monitors refused to behave the same until I went through all their menus & set everything identically. One would think brand new monitors straight out of factory sealed boxes would be set the same, but they weren't. Go figure.

    Sorry, but that is correct. You need Snow Leopard to sync your phone and the latest version of iTunes and you old G5 cannot run that.

  • Problem installating Snow Leopard on old Macbook Pro with Intel Core 2 Duo. After creating partition on internal hard disk (Extended Journaled), installation starts but stops at half of the progress bar. Screen asking Restart appears.

    Hello:
    I have tried installing Snow Leopard via the installation disc on a Macbook Pro (2007) with an Intel Core 2 Duo, but I the installation has failed more than 5 times.
    I have first formatted and partitioned the internal hard disk with Mac Os Extended Journal format.
    Once the installation starts, it starts without a problem unti lthe progress bar gest until half completed then a screen asking for a Computer Restart shows up.
    It asks to press the power button for some time until it the computer shuts down and then, press again to turn it on.
    Once turned on, the installation disc gets readed, the installation screen appears again and asks again to start the whole installation process form the beginning.

    Then you have a Hardware Problem.
    Your system is Crashing part way through the install and Re-Booting because of the crash.
    Could be the drive itself or it could be some other hardware part in your system. Like the RAM.
    To check if it is the internal drive connect an External drive to the system by USB and do the install on that external. If the install completes then it more then likely the drive is bad. If it crashes again then it is more then likely some other piece of hardware in your system.
