Constant crash in /System/Library/Extensions/GeForceGLDriver.bundle/Contents/MacOS/GeForceGLDrive r

I have a 2010 unibody Mac Mini.  It came stock with a 320GB HDD and i have upgraded it to 8GB of Apple approved Kingston RAM.
The machine worked just fine under Mac OS 10.6.8, could be up for days and days and be perfectly stable.
Since upgrading to Mac OS X 10.8, i have had constant crashes in Safari, and a bunch of other apps and the only thing really similar between the messages is the following line:
/System/Library/Extensions/GeForceGLDriver.bundle/Contents/MacOS/GeForceGLDriver
This error has caused many apps to crash, including but not limited to:
Safari
App Store
VLC
Quicktime
PhotoBooth
Activity Monitor
Safari seems to be the main culprit, it crashes constantly, i can use it for a bit, then it will crash, sometimes it will crash again directly after re-launch.  There doesn't seem to be any rhyme or reason. Apps do not quit in a cascading fashion, apps that have previously quit with the same line in the logs have not occured concurrently with other crashes at the same time.  I have created a guest account to test the system and I'm having the same issue globally, so i've managed to mostly rule out my profile.  I have no extentions installed and no plugins other than Flash and Silverlight. There seems to be no direct correlation between the use of either of these plugins when the crashes occur. Removing these plugins does not alleviate the problem.  System can be heavily loaded, or entirely idle.  I've come home from a 12 hour day to find a couple apps have crashed during the time i was gone. 
App store was the only app running when it crashed.  The only other noteable thing to add is that after the crash occurs, the system will spin up all the connected external drives. I have tried disconnecting all external drives and peripherals and have been met with the same issues.
Anyone have any thoughts one what may be causing this and how it may be fixed (Short of reinstalling...)?

Hmmm, it'd make Safari less usefull & AppStore might not work, but try disabling Javascript in Safri & browse best you can.
The symptoms without the logs are reminiscent of a RAM problem.

  • Permissions repair: SUID file system/library/coreservices/remotemanagement/ARDAgent/contents/MacOS/ARDAgent has been modified and will not be repaired

    I have a mid 2007 iMac running OS Mavericks and the hard drive is failing. When doing a disk permissions verify it shows  SUID file system/library/coreservices/remotemanagement/ARDAgent/contents/MacOS/ARDAgent has been modified and will not be repaired. I do not have a backup of my system due to my external drive I use for backing up my system has stopped working. Can I repair this myself without having to reinstall the OS so I don't loose my any of my files.

    You can safely ignore that.

    If you run Parallels, there is a conflict with 10.6.8.  One of the symptoms is the dock at 100%.
    The cure is update to the latest Parallels.

    HP printer problem after upgrade!  Any fix?

    Try a reset of the printing system.
    Open System Preferences > Print & Fax
    Move the cursor over the Printers list
    Hold down Control and click
    Select 'Reset printing system' popup
    This will delete all your print queues but not the drivers, so you will only have to add the queue to the HP again.

  • I upgraded from OS 10.4.11 to 10.6.8 and now cannot print to my Epson Stylus Photo RX595. When I try, I recieve the following error message: Error:/System/Library/Printers/Libraries/PrintJobMgr/Contents/MacOS/PrintJobMgr failed. Is this a driver issue?

    Is my inability to print from my Intel iMac with OS 10.6.8 related to a driver problem? I checked the Epson website for up-to-date drivers, but they appear to only have print drivers good through OS 10.5x. I did the Apple software update yesterday so everything is up-to-date. Is there no support for the Epson RX545 under OS 10.6x?

    When you upgrade from a previous OS there is always a chance that you will bring some setting that is not compatible with the new OS. This can be the driver as noondaywitch suggests but it can also be the core printing system. In the case of the latter, it is a good idea to reset the printing system when a core error occurs. Note that the reset sets the printing system back to default and removes your currently installed printer and scanner queues. But it does not remove the supporting drivers, so you only need to install the driver again.
    How to Reset the Printing System
    1. Open System Preferences > Print & Scan/Fax
    2. Move your mouse over the Printers list
    3. Hold down the Control button and click the mouse
    4. Click the "Reset printing system ..." popup
    5. Restart your Mac
    Just one additional thing to note. In checking the supported printer list for 10.6 from Apple, your RC545 is not listed so running the Software Update will not provide you with a driver for this printer. So if Epson does not have a driver for 10.6, and it appears that Apple does not provide one, then what you have already from the previous installation is it. And if this doesn't work, then you may have to look at either an alternate driver or getting another printer. But let's wait and see what happens after the reset.

  • Got error message - //System/Library/Extensions/AppleUSBEthernetHost.kext" was installed improperly and cannot be used.

    Was updating at the App Store - Safari, iTunes, iWorks 09 and prior to that had updated something at Adobe's website.  Then this error message popped up:
    “//System/Library/Extensions/AppleUSBEthernetHost.kext” was installed improperly and cannot be used. Please try reinstalling it, or contact the product’s vendor for an update.
    (I  just received a refurbished computer with a new hard drive from a local Apple repair store...
    Is this an easy fix.  Thanks, Charlotte

    What I ended up doing is a reinstall the OS.
    There was an important component I forgot to mention...my hard drive had crashed and I had it replaced.  When it was replaced - the old drive was copied to the new.  Since the prior error messages I had gotten from MemTest and CheckMate kept saying Bad Blocks in the drive - it was suggested that the corrupt or missing data on these "bad blocks" had not copied or copied incorrectly.
    So only time will tell if this fixed this error.  (Don't have external hard drive so never had Time Machine set up to begin with.)  Original computer was refurbished and believe some things weren't done right from the get go.  Oh well...  Hope I didn't lead anyone astray.

    Are you still using some sort of network usb dongle.
    That kext is for some network device and it apparently wasn't written correctly. If you're not using it, uninstall the device software using the manufacturer's uninstall utility.
    If you are using it, contact the manufacturer and see if they have an update that works correctly in Lion.

    System extension cannot be used.
    The system extension "/System/Library/Extensions/PACESupport.kext" was installed improperly and cannot be used. Please try re-installing it, or contact the product's vendor for an update.
    How can I fix this?
    Thanks.

    The extension is not an Apple-supplied one. It is an obsolete anti-piracy extension, suppled by Pace Anti-Piracy, Inc. & installed with a few applications such as older versions of Cubase. See Apple > Support > Discussions > Mac OS X v10.4 Tiger > Installation & Setup > PACESupport removal for more info about it & how to get rid of it.

  • ITunes 9 Installation - /system/library/extensions/CNQL2410_ClassicNotSeize

    When I installed ITunes 9 I received the error message "System extension cannot be used /system/library/extensions/CNQL2410_ClassicNotSeize.kext was installed improperly". The ITunes 9 installation completed successful and seems to be working OK.
    On another discussions I read about similar issues related to Snow Leopard and e.g. CanonScan LIDE 500F and other third party software.
    Anybody a suggestion how to correct this problem?

    This has showed up since I upgraded to Snow Leopard, and this dialog came on the screen after upgrading iTunes to 9.01. I have previously had the scanner software installed on the computer - it doesn't work after upgrading to Snow Leopard. I don't have Rosetta turned on.
    I would just go take out the file, but I don't want to mess anything else up in the process. Anyone know if we can just take out this file, or should we uninstall the Canon Lide scanner software?

  • //System/Library/Extensions/AppleUSBEthernetHost.kext

    I got a message saying that this:  //System/Library/Extensions/AppleUSBEthernetHost.kext was not installed properly and needed to be reinstalled.  How do I do that?

    Thanks to you both, this fix worked for me too, after long ignoring the error message and vainly waiting for Apple to get around to an update.
    Then last night I lost my Internet cable connection, which uses Ethernet between the modem and my iMac (Max OS X 10.6.8). At first, I blamed my ISP because the modem played up for a while, but after I rebooted it a few times, it returned to normal, but I still couldn't get online. I suspected, rightly or wrongly, that this faulty kernel extension might be the culprit. It took me 90 minutes' fiddling to obtain a slow Internet link, but that enabled me to download iTunes 11.4 from Apple.
    I cautiously created a "Pre-trash" folder in which I dumped the non-functioning AppleUSBEthernetHost.kext and a back-up of iTunes library files before using the iTunes installer, with an eye on the open //System/Library/Extensions finder window. When the new kernel extension popped up in it towards the end of the installation, I noticed that it bore the date July 29, 2014! Its predecessor dated from mid-2009. This is not the first time in many years that an iTunes upgrade via Software Update has caused problems, usually corrected by downloading directly from the Apple site.
    I fixed permissions for good measure and have found that my Internet connection is also nice and fast again, but I have no idea whether that's pure coincidence.
