10.6.8 Causes New Problem with Mixed Graphics Hardware Environment - Suggestions?

Hi. After installing the latest Mac OS update (10.6.8), I can no longer boot my 5,1 Mac Pro into its Mac OS partition.  An undefined display (and graphics card) now seems to be used as default, rather than the supported display/hardware, so I cannot interact with the user interface.  I simply have an inoperable blue screen on the correct display. I have 2 graphics cards in my Mac Pro: a supported GT120 (solely for the purpose of booting/using Mac OS), and an unsupported HD6970 (used extensively for Windows 7 3D gaming, in Slot 1).  Until this latest OS release, I could successfully boot and use my computer in both Mac OS and Windows environments.  I encountered other problems because of this mixed graphics environment, like an inability to put the system to sleep without having the Mac Pro PCI fan unnecessarily ramp up to full speed after waking - but it would always work correctly when first booted.  (I have contacted Apple Support about this sleep issue, but they do not support my configuration.) Does any boot command exist to force the use of the supported graphics card?  Or, do kext files exist to enable the Mac OS to at least recognize (not use) the 6970 card? With the 6970 removed, I have no problems booting the Mac OS, but I do NOT want to remove my hardware card every time I want to shift to the Mac OS.  Do anyone have any suggestions?

Thanks for the suggestions.
First, I cannot swap graphic cards in PCI slots, because the 6970 only operates correctly in slot 1 (the high-speed graphics slot).  I may have to revert to the prior OS release, but what about next month, with Lion?
I am familiar with Netkas.org (I will probably try it or Groths.org next, thanks).  One of my previous graphics cards was a flashed 4970.  I do not have access to the prelease Lion kext files that he suggests using.  Full flash support does not appear to yet exist for the 6970, much less the HD 6990 or GTX 590 that it appears I may need next.
Ideally, the Mac Pro firmware should ignore any attempted bus communication with an unrecognized PCI card.  Currently, it appears that the unsupported 6970 can cause boot or run-time problems (I also have occasional freezes during Mac OS hardware interaction like writing a file to disk).  Note that I have never had any problems arising from my unsupported Windows 5.1 PCI sound card, however.

  • New WIN7 System, FFox gives error "Could not initialize the application's security component. The most likely cause is problems with files in your application's profile directory" - will not go to any site.

    New Windows 7 computer. After installing Firefox, every time I bring it up I get the following message:
    "Could not initialize the application's security component. The most likely cause is problems with files in your application's profile directory. Please check that this directory has no read/write restrictions and your hard disk is not full or close to full. It is recommended that you exit the application and fix the problem.

    Then Firefox comes up, but will not function at all - can enter url address, but will not respond to ANY clicks, so can not go to any site.

  • Two new problems with the Quicktime Plug-in

    I recently discovered two new problems with the current Quicktime Plug-in for Mac OS X.
    First, the Quicktime Plug-in is unable to stream Quicktime media in any internet browsers other than Safari.
    There is just nothing on the spot where the embedded Quicktime player should be.
    Second, the Quicktime Plug-in only shows the message "The operation couldn't be completed. This file is not a movie file (-2048)"
    everytime it should work together with the Flip4Mac Plug-in. The thing is, when facing a webpage where a wmv or wma file is
    embedded, there only shows that error message on the spot where the player should exist. I first thought that it would be a
    problem with Flip4Mac. So I uploaded about this problem on telestream.net, only to hear that the error message above belongs
    to the Quicktime Plug-in.
    Both of these problems did not happen at all only three weeks ago. The embedded Quicktime player showed up without any problem
    in my Firefox and Opera, and wmv or wma files were streamed successfully through the Flip4Mac and Quicktime Plug-ins.
    Then, suddenly, after some point, these two problems began to occur, and there is no information on how to solve them on the web.
    I obviously tried uninstalling and reinstalling Quicktime. I even completely erased the hard disk of my Macbook, and reinstalled the
    whole Mac OS X. But the problems still remained. I borrowed another Macbook from my friend to check whether these problems
    occur in other computers, and they did occur in my friend's Macbook as well. So they are definitely not the matter of my own Macbook only.
    I think these might be the problems with the new Quicktime Plug-in 7.7.1.
    Please check about these problems and solve them on the next version of the Quicktime Plug-in.
    I will give you a couple of hyperlinks so that you can check about the problems directly.

  • The upgrade to Firefox 4 is causing massive problems with my computer. How do I uninstall it and go back to using the previous version?

    Firefox 4 is absolutely awful - it is causing massive problems with my computer. How do I uninstall Firefox 4 and go back to the previous version of Firefox?

    According to the instructions given on the Norton Community forum under "Other Norton Products/Comcast-Customers - Norton Toolbar Problem in Firefox 10", I have done everything necessary. And I do have a Norton toolbar (Safe Web and Identity Safe) when I open Firefox 10. As was mentioned in the previous posts here, you need to run manual LiveUpdate then reboot until you have version 5.2.0.13. Then reboot and run manual LiveUpdate again and reboot once more. One thing that I noticed is that Norton never told me that it had updated the patch for Firefox 10, so I didn't know. I guess if you have the toolbar when you run Firefox 10, then you have done it all.

    In Mac OS X v10.7, the $HOME/Library folder is a hidden folder.
    Open Finder and use one of these:
    * Go > Go To Folder (Shift-Command-G) and in the dialog type: ~/Library
    * Open the "Go" menu and hold down the Option key to make the Library appear
    You can also use this command in a Terminal window to remove the hidden flag.
    * Mac HD > Applications > Utilities > Terminal
    * chflags nohidden ~/Library

  • Update to OS 10.6.5 causing video problems with FCP

    I stupidly updated to 10.6.5 this morning and ever since all video displayed in FCP appears to be underexposed by 5 or more stops. To give you an idea, it looks as if I applied 3-way color corrector and crushed the blacks 1/2 to 3/4 of the way down. This happens to all video in both the canvas and viewer window no matter what project I have opened. At first I thought maybe it was a problem with my graphics card but all of my qt files play fine. And if I go to the clips I am referencing in FCP they are fine when viewed through quicktime. I have tried the following:
    move media to a different location and reference from there
    install the combo version of OS 10.6.5
    trashing my preferences in FCP
    completely reinstalling FCP
    none of these have worked.
    I assume the other idea would be to reinstall my OS back to 10.6.4 but then I would have to wipe my hard drive right?
    Very frustrating because I am in them middle of a project and now I can't work.

    Someone will say "Restore your backup, the backup you made before you upgraded to 10.6.5." Just warning you.
    I'm also using 10.6.5 but I've not seen what you're describing. Maybe something is that more specific to your setup is causing it. If you export a QuickTime movie is it also fine or is your video output fine? If it is then you can keep working, because you know that the problem isn't affecting your output.
    Going back to 10.6.4 may be the thing to do, and yes you'll need to wipe your drive. So back up your system as it is now just in case the 10.6.4 reinstall fails spectacularly.

    Thanks for the links, Limnos.
    If you are willing to continue helping, here's what I found.
    Just to clarify the two iTunes folders I am refering to are:
    username-->Music-->iTunes
    HD-->iTunes
    I am presuming each location has a full set of files as outlined in the above links?
    Not all the files are in both locations. Most are.
    - The Itunes folder in my home folder does not have itunes library.xml.
    - The Itunes folder in my home folder has a subfolder called Mobile Applications (username-->Music-->iTunes--> Mobile application). The Itunes folder at the HD level also has a Mobile Application folder but it is a subfolder of Itunes Media folder (HD-->iTunes--> iTunes Media-->Mobile applications) and has no files in it.
    - I do not have an iTunes Media in the iTunes folder in my home folder.
    - also the Itunes media folder (HD-->iTunes--> iTunes Media) has subfolders by type (books, movies, itunes u, music etc...) but the iTunes Media-->Music also has some of the same subfolders ( iTunes Media-->Music-->books, iTunes Media-->Music-->Movies, iTunes Media-->Music-->iTunes U). Is this normal repetition?
    You say:
    /itunes/itunes media/ music
    but it is important to note what comes before all that.
    There is nothing as far as I can tell before that first forward slash. Since the only iTunes Media folder I have is in the iTunes folder that resides at the HD level (HD-->iTunes--> iTunes Media folder) not the iTunes folder in my home folder (username-->Music-->iTunes) , I assume that's the one that holds the music.
    Keep iTunes media folder organized and Copy files to iTunes Media folder when adding to library are both checked on
    Does that give more clarity into my problem?

  • New problems with Acrobat 11.03 for Mac

    I'm having new problems with my Adobe Acrobat 11.03 for Mac.  These issues are relatively new and did not occur when I first bought the product about 9 months ago.
    1) When scanning documents from an HP scanner into Adobe on my Mac, the scanning works fine, but a multi-page document (scanned as one) is saved as a separate PDF for each page.  Bothersome to then have to combine all those separate files into one doc.  I can do it, just don't think I should have to take the time.
    2) Occasionally, when working in Adobe, the menu bar at the top will disappear when I click on the Adobe icon or a previously saved PDF.  Very frustrating.  Can't make a note or save the document without knowing the shortcuts, as the menu has disappeared.  Once I click somewhere outside Adobe, the menu bar reappears for the other programs.  This happens over and over. 
    Any ideas?
    Thanks.

    Hey JeffSPHR,
    Please refer this KB doc link mentioned below and try troubleshooting scanner issues:
