Is there a way of stopping the kernel from trying to load a device???

Hi,
Basically I have a Nvidia 7950GX2 that i have installed in a Mac Pro to use in windows and it works perfectly but when i try to boot into OSX i get kernel panics.... I still have my 7300 in the machine for OSX. when I try this methos with a 7800 gtx it works just fine.....
Is there a way i can stop OSX trying to load the device on boot? disable it
Thanks in Advance...................

Video cards that do not have Apple ROMs cannot boot an EFI based machine like the Mac Pro.  Currently the only video cards that will properly work in the Mac Pro are the three available from Apple.  You can read more about this in the Mac Pro forums by doing some searching and browsing because the topic has been widely discussed here.  You will also find more at www.xlr8yourmac.co, www.barefeats.com, and the review of the Mac Pro at www.anandtech.com.

  • Is there a way of stopping the battery from charging?

    Dear Apple Community,
    Recently I installed iStat Menus and found that, over the course of this year, my Macbook's charging capacity has dropped 5%. I know this isn't a massive number, but battery performance has become a concern for me. I use my Macbook as a desktop replacement, on the main. It's sitting on a mStand, connected to a large monitor on my desk. I use my Macbook to play games, surf the internet, do work and all that good stuff - basically, I use it for everything. I rarely use the Macbook without it being plugged in. I read on the Apple website that they do not recommend leaving the Macbook on charge permanently and that I should use it on battery at least one a month. As I use my Macbook as a desktop replacement, I don't actually have a lot of opportunity to do this.
    My question to you, the community, is: is there a way of stopping the battery from charging, either with the use of an app or a physical device? Ideally, I would love to have my power plugged in BUT only used when the battery drops below 10%. Is this possible with an app?
    On the other hand, am I just worrying about nothing? Will my battery be damaged further if I leave the Macbook charging permanently?
    Thanks for your help!

    Ideally, I would love to have my power plugged in BUT only used when the battery drops below 10%. Is this possible with an app?
    The charging characteristics are handled in firmware.  There is no app that would be able to do this.  You actually would not want to do this anyway.  Regularly discharging your battery to 10% will greatly decrease the life of your battery.  While it is true that you should not use your system exclusively plugged in, allowing it to run on battery a few hours a week should be fine.  Letting the battery regularly run down to (or below) 10% will cause you to use up cycles more quickly than is necessary (thereby reducing the life of your battery).  It's really a only a matter of disconnecting your Magsafe connector once in a while.
    Leaving it plugged in does not result in it being charged "permanently".  It will charge until it is full and then charging will stop.  It will only begin recharging when it reaches about 95%.

  • Is there a way to stop the OS from switching to a newly opened app?  I would like to be able to continue what I'm doing while I wait for an app to launch and not get interrupted by a forced entry into the app.

    Is there a way to stop the OS from switching to a newly opened app?  I would like to be able to continue what I'm doing while I wait for an app to launch and not get interrupted by a forced entry into the app.
    As an example, I'm going to my email in safari, while I wait for it to load, I open an excel document, and the OS decides excel should be the front app, so I go back to safari so I can enter my login info, but halfway through my password the OS decides that excel is where I should finish typing my password.
    VERY ANNOYING.  Can I open apps in the background?

    Thank you everyone for the suggestions. J D, I'm not a terminal fan, but I'm sure it works.  I found a solution that I can use in the dock from another post.

    Works great and allows me to maximize those multitasking minutes.

  • On my iPad 3 is there any way to stop the pictures from flipping 180 when saved?

    When I take pictures with my iPad, when the pictures save they always flip to the opposite side. Like a mirror image. I am wondering if there was anything I can do to fix this as it is extremely annoying!

    Yes the calendar is gone. I guess it is the notification center I am referring to that comes down when I accidently swipe the top of the screen. Is there a way to stop of notification center from coming down if you swipe the screen? I figured out how to stop the control center from coming up if you swipe the bottom on the screen. Now I just need to figure out how to stop the top of the screen from doing the same thing

  • Is there a way to stop the brightness from going up when alarm goes off?

    I have an iPhone 5s running iOS 7.0.6. I plug it in at night next to my bed and use it as an alarm clock. I am running the NiceClock app because it has a great black background with slim red clock numbers (doesn't throw a lot of glare). I am using the built-in Clock app that comes with the current iOS as the alarm (NiceClock, while great for a simple bedside clock with no glare, does not come with an alarm). I set my iPhone's brightness on the lowest possible setting to keep the backlight glare down. It's great. Low glare, and I can still see the time if I wake up in the middle of the night without having to fumble with the iPhone. My problem is when the alarm goes off the brightness level jumps up to maximum. Is there a way to prevent the brightness level of the iPhone from changing when the alarm goes off?

  • Is there a way to stop the calendar from linking to keywords in text messages in IOS 7?

    With the new upgrade to IOS 7, I've noticed that certain keywords such as "tonight," "tomorrow," or times like "9:15" all underline and form a link to the calendar in text messaging. Is there a way to turn this feature off? It's quite annoying as I don't create events from my messages.

    I find this annoying as well, and cannot fathom why there isn't an option to disable it for those of us that find it irritating.

  • Is there a way to stop the screen from updating till the code is executed?

    My extension needs to export all the layers to PNGs and it creates a lot of moving around in the screen while the operation is complete (eg: switching between layers, cropping the images, etc). I've set the Playback mode to Accelerated as well.
    Is there a way to not update Photoshop UI during the process? (I have seen similar functionality in Microsoft Excel/VBA scripting)

    As a shameless hack: put a layer on top, fill it with the color you like the most and that will prevent the document from revealing what's going on below.
    It's a bit like hiding the dust under the carpet, there might be cases when you need to turn it off (e.g. merge on top) but for basic stuff it does the job.
    Besides that, there's a undocumented "viewless document" or something like that, but you can do very limited processing - XBytor wrote something on ps-scripts.com years ago.

  • Is there any way to stop the top from scrolling left in the iTunes store?

    The top part of the iTunes store...where it lists new stuff keeps swiping left.  It's driving me crazy!  How can I stop it?

    You can't . It is used as a carousel to display new items. If it annoys you then scroll down the window until it dissapears and you will have a static displays of new Music, Movies etc

  • Is there a way to stop an ipad from trying  to copy pictures and text?

    I have a lot of scrolling text boxes in my project, and I want certain symbols to play when a particular text box or image is touched, but the ipad will offer you the option to cut, paste, copy etc...when one holds their finger on the text for more than a second (very annoying). Is there a line of text I can put in to disable these options for all text and objects, but will still allow individual actions to be written for certain text boxes and objects?
    My test page can be viewed here, and one should be able to viewed/download the edge files from this page (sorry they're not zipped).
    Any help is much appreciated,
    Thanks

    If the previous owner is alive, no.
    If the previous owner is dead, take the device, its original purchase receipt, and that person's death certificate to a physical Apple Store.

  • I lost my ipod whilst travelling, is there a way to get the photos from it onto a new device using iCloud?

    If you had turned Photo Stream 'On' , you can retrieve your photos as they should appear in 'Photo Stream' in iPhoto on a Mac or on an iPhone provided you are signed in using the same Apple ID as your iPod Touch

    Hi all.  Is there a way to stop the mail icon from bouncing on the dock when a new message is received?  It's irritating.  I'm running Lion.  Thanks.

    Thank you Linc.  I knew that I did something in system preferences to cause it to bounce, but couldn't remember what I did.  I appreciate your help!  Kelly

  • Is there a way to stop the launching applications to come to foreground?

    Is there a way to stop the launching applications to come to foreground?
    Back with os 10.3 Panther or 10.4 Tiger the apps opened in the background. That was one of the good differences with Windows. I guess that 10.5 Leopard adopted this annoying Windows behavior. Hope it's gonna change with 10.7 Lion.
    (Of course I am looking for another solution than the AppleScript/Terminal launch that can be found on Google. I'd rather have a plist option to change if it exists!)

    I have found this page http://www.realsoftware.com/listarchives/realbasic-nug/2009-03/msg01167.html where it is proposed to add :
    <key>LSBackgroundOnly</key>
    <string>True</string>
    to MyApp.app/Contents/Info.plist
    I tried this but the app launches totally hidden in the background. Plus you have to set this behavior for every app.
    The open -g option works fine as expected.
    Still looking for a system-wide option, but it doesn't seem to exist.
    About the utility of such an option, I'll just remember you that some machine don't load apps very fast and, instead of waiting for an app to launch, the user will do something else until the app launches. You'll understand that waiting in front of a computer isn't acceptable and having a MBPro isn't possible for everyone.

  • My laptop was stolen lately with iCloud activated on it. I realize that i can remotely wipe it using find my phone but I really doubt that the thief will go online. So is there a way to stop that laptop from getting my iCloud updates? Please help.

    Hi,

    Help.

How can I find out the IP's that are connected to my icloud. That lack of information who is connected to your icloud is not qool . Sorry for my english.

  • Is there any way to stop the print screen from dropping down on top of the page to be printed.  Can the print screen be moved?

    Is there a way to stop the print screen from dropping down on top of the page to be printed.  Can the print screen be moved?  When the print screen drops down, it covers the page and the info needed to create the file.  Thank you

    You will find that this is application dependent.  Most Apple applications such as Safari and Mail will use the "sheet" type of dialog boxes that you are referring.  There is no way for the user to change that behavior.  Other, non-Apple, applications like Firefox use a "modal" dialog box for printing etc.  The modal boxes can be moved around so you can see the page behind.

  • Is there any way to stop the delay between different sets of speakers when using airport express?

    Is there any way to stop the delay between different sets of speakers when using airport express?

    Unfortunately, I don't have either a Slingbox or iHome speakers so I won't be able to reproduce any of the issues you are having. With the fact that you live in large apartment complex would still lead me to believe that Wi-Fi interference may be the reason that you are having streaming issues.
    I suggest you perform a simple site survey, using utilities like iStumbler, or AirRadar to determine potential areas of interference, and then, try to either eliminate or significantly reduce them where possible.
