Q: 24" iMac Screen Freezes since 10.6.3 update - pls help!

I don't know if this is just coincidence or not, but since updating my iMac to 10.6.3 it keeps on crashing. On 3 separate occasions today, whilst using my Mac the screen has gone completely black with thin white lines down it.....see pic below:

http://picasaweb.google.com/lh/photo/6SYzhCgVYEU5TBKqRfOQ1Q?feat=directlink

The fans and hard disk are still running but it will not respond to any keyboard or mouse presses - I simply have to turn it off by holding the power button in.
It will then restart as usual.

Anyone got any ideas? Do you think that if I was to re-install Mac OS X from my original install disk it could solve the issue?

Thanks

Darren

    Thanks, I have found the files in this old post Re: 24" iMac Screen Freezes since 10.6.3 update - pls help! 

    This might be usefull for the next ones.

    I did the kext exchange on a 7,1 iMac, on 10.11.4, it's running well, no problem with the sleep mode. However I had to keep SIP disabled because SIPutility would give me an error message as H4nd desribed above, and only the x2000 kext was active when SIP enabled.

    Hello!!

    One day my iMAC 20" begining 2008 with ATI Radeon HD 2400 XT 128 Mb died....

    Then I decided install the new OSX, but I tried with a lot of versions, 10.7, 10.8, 10.9, 10.10, 10.11....and always the same error, I can install normal, but in the first start  never started, only in safe mode, but thanks a this post and his greats manuals I can run the system in normal mode... But i have a big problem, the graphics system is too slow, and the repainted is bad, very bad....

    I think is a problem with the driver, but I'm not an experto on OSX system,

    How Can I do?

    Thanks so much!!

    bigskywolfe: I've got the same issue as you; sleep no longer works after installing the old kexts. I just checked System Profiler and the old loaded kexts are not loaded. I can see them there, but the status is "not loaded." Maybe I need to unable SIP again? I'm pretty sure everything was working after I initially did the fix. Maybe the next restart killed it. If anyone else is seeing choppy performance, and an inability to put the iMac to sleep, the ATI kexts might not be loaded any more.

    Thanks for the reply. I'm glad someone else was seeing this issue as well. As you suggested, I looked at my System Profiler and, sure enough, it showed that the 10.6.2 kexts were not loaded. So, I booted back into recovery mode, ran the "csrutil disable" command, and restarted. Everything checked out at this point - the 10.6.2 kexts were showing as loaded. Once again, I rebooted into recovery mode, ran the "csrutil enable" command, and restarted. Now the 10.6.2 kexts are still loaded and I'm back in business - no screen freeze and sleep works properly! I'm not sure why the 10.6.2 kexts didn't load properly the first time I ran through the procedure. Thanks Daniel Smith-Weiss!

    I have a iMac (2007) working on OS X El Capitan and my computer crashes all the time.

    I was checking all the comments here but I didn't see anybody talking about version 10.11.5 which I have now.

    I have not tried to do what Mr. Daniel Smith-Weiss said to do because I am not sure how should I start.

    What should I do? Please anybody can help me?

    Hi,

     

    My 2007 iMac runs 10.11.6 just fine, never did the 10.11.5 upgrade.

     

    One way to test is to Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, Test for problem in Safe Mode...

     

    PS. Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive & trash/rebuild cache files

     

    Reboot, test again.

     

    If it only does it in Regular Boot, then it could be some hardware problem like Video card, (Quartz is turned off in Safe Mode), or Airport, or some USB or Firewire device, or 3rd party add-on, Check System Preferences>Accounts (Users & Groups in later OSX versions)>Login Items window to see if it or something relevant is listed. Or an errant process eating up RAM.

     

    Check the System Preferences>Other Row, for 3rd party Pref Panes.

    Considering this is the Mountain Lion forum, that would explain why no one was mentioning El Capitan.

     

    Suggest you start a new "Post" in the El Capitan forum, and post a few of your system panic report

    Kernel Panic reports: "/Library/Logs/DiagnosticReports"

    <http://support.apple.com/kb/ht2546>

    <http://support.apple.com/en-us/HT200553>

    The panic report should have "panic" in the file name.

     

    You might also consider posting the EtreCheck output in your new "Post" in the El Capitan forum.

    <https://discussions.apple.com/docs/DOC-6174>

     

    <http://etrecheck.com>

     

    This thread is way too long to do any serious system panic debugging.  When thread get this long, a lot of people stop looking at them, so you are limiting your chances of getting any real help.  Please start a new "Post" in the El Capitan forum.

    I'm still able to use davidefrombruino's method on 10.11.6.  However, I noticed that if I didn't run the SIPUtility, the 10.6.2 kext would not load, but on my iMac 7,1, ATIRadeonX2000 from 10.11.6 will load, and iMac still works, although all the display options are missing so there's only one resolution.  If you're afraid of messing with SIPUtility and disabling SIP, perhaps this is an alternate method.  I was able to remove the 10.11.6 kexts by booting off another drive, so I can edit the 10.11.6 system folder.

    Hi Davide.

    Sorry for my bad English too.

    I have an iMac 2007 working with OS X El Capitan and I have the same problem.

    I didn't try your procedure yet but now I have one more problem. My computer just crashes. Turned off and turned on by nothing. Do you have this kind problem too?

    You might want to consider starting a new discussion. Since this one is a couple of years old, less people are likely to look at it. A new post would be much more visible. You can link to this one. Post in the El Capitan community.

    Unfortunately this driver issue can prevent iMac from starting up under El Capitan.  I had to work around this by booting up with Mountain Lion, then reboot to El Capitan recovery disk

    This thread is a bit long, and if you do not get satisfaction, because many helpers tend to ignore long threads as being just too confusing to figure anything out, you might consider starting a new thread in the El Capitan forum, as you are not running Mountain Lion.

     

    There is a strong chance you just have too little RAM to run El Capitan AND the resource hog Chrome.

     

    Unfortunately, you model iMac can only go to 6GB or RAM.  While better than the 3GB you currently have, it is really not much these days.  And especially not much when you want to run Chrome.

     

    You might be able to compensate by replacing the rotating hard disk with an SSD, so that when you do start paging/swapping to disk, it will not take as long to complete, but that just might be money better spent on getting a newer Mac.

     

    Speaking of your disk, your system is sufficiently old, that it is possible your current disk is generating lots of silent retries where the disk is retrying reads multiple times until it gets a good result, slowing down your disk access.  This can severely affect performance.  You could make a Genius Bar appointment at an Apple store and have them check the disk.
