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?

  • Every time I install an update of itunes, I get an error message saying: "/System/Library/Extensions/WkClassicNotSeizeDriver.Kext" was not installed Correctly. Has any one had it? Can you help me?

    Every time I install an update of itunes, I get an error message saying: "/System/Library/Extensions/WkClassicNotSeizeDriver.Kext" was not installed Correctly. Has any one had it? Can you help me?

    Find out what that third party software the kext file belongs to and update or use the developers method to uninstall the third party software responsible for it.
    I suspect it's a iTunes extension perhaps?
    You also can use the manual method of Finder > Go > Computer and opening your drive, then your  System/Library/Extensions folder and looking for the file and moving it out onto the desktop, you will need to be in Admin user and use your password, then reboot to clear the random access memory. However this method doesn't remove the parent program you still need to do that.
    How to uninstall/install software on your Mac
    The kext file wasn't loaded, so it's not running, but removing it from the Extensions folder or uninstalling what put it there will solve your notification problem as that's all it appears to be.

  • //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.

  • /system/library/extensions/AppleUSBethernet host.kext not properly installed

    Message on pro: /system/library/extensions/AppleUSBethernethost.kext not properly installed. What can I do?

    Open the Script Editor in the /Applications/AppleScript/ folder, copy and paste the entire following line into it, and press the Run button:
    do shell script "chown -R root:wheel /System/Library/Extensions/AppleUSBEthernetHost.kext" with administrator privileges
    If it doesn’t work, choose Go to Folder from the Finder's Go menu, provide /System/Library/Extensions/ as the path, throw the AppleUSBEthernetHost.kext item away, and reinstall iTunes; if you’re running Mac OS X 10.7 or newer, get the installer from Apple’s iTunes site instead of the linked article.

    Received following message during installation of an iTunes update today (9/16/14):  System extension cannot be used.

Please try reinstalling it, or contact the product’s vendor for an update.  What is to be done about it?

    Thanks for the reply.  I'm not experienced in the inner workings of the iMac system and its programs, so please follow my train of thought as I try to find and understand your reply.
    You wrote that I should check out "Please see - AppleUSBEthernetHost.kext error on installing iTunes update" and I did so.
    There I found your reply of 9/1014 7:06 PM to j'ski stating: "There is a larger thread here which you may want to follow - system extension cannot be used AppleUSBEthernetHost.kext ."
    And an earlier Post by Greg Earle of 9/10/14 5:57 PM stating: " You would have been better off doing open /System/Library/Extensions and then finding the AppleUSBEthernetHost.kext kernel extension icon in the Finder window that came up and moving it to the Trash."
    And a subsequent Post on 9/15/14 at 2:59 PM by Rob Maurer stating: "This method worked perfectly for me.  I am on a Mac Pro running Mountain Lion. Dragged the kext file to trash (I use EasyFind. Found the file, Revealed in Finder, dragged to Trash, entered admin password when requested). Downloaded iTunes 11.4 from the website. Installed from that download. Checked for that kext file in EasyFind again and found it had a creation date of 7/29/14 (the trashed one had a creation date from 2009). No more error messages.  ITunes opens fine.  Everything good. Will not update on my MacBook Pro until they fix this issue.
    All of which leave me wondering - what is your answer/recommendation?  Do I drag the kext file to trash, download iTunes 11.4 from the website and install it from that download, check for that kext file again to see if it has a later date than the initial one?  And, if so, seed if iTunes opens okay or not?  And if so, do not update iTunes again until Apple fixes whatever is wrong?

  • "/System/Library/Extensions/PACESupport.kext"

    After finally installing Snow Leopard today and updating to 10.6.4, I've been getting this error message appear sporadically:
    System extension cannot be used.

    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.

    Hello, I have this; "/System/Library/Extensions/CDSDAudioCaptureSupport.kext" How can I fix it from Terminal?
    Thank you!

    Do you see the file in the location indicated?
    Do you have a backup of your hard drive and can you find the component on it?
    Sometimes running a Snow Leopard updater may  install the component if it has been updated since the original version of Snow Leopard.  In the end you may need to reinstall your operating system using your Snow Leopard installer disc. Alternatively you can extract individual components from an installer disc using the Pacifist utility.
    Kappy: How to Use Pacifist to Replace Deleted or Missing OS X Components - http://discussions.apple.com/message/9044169 and another https://discussions.apple.com/message/17864069
    Before doing any of this I would boot from your installer disc and run Disk Utility to repair your hard drive.  Components should not just go missing and this may indicate more serious issues with your files.

  • Hi - I think on my mac /System/Library/Extensions/AppleUSBEthernetHost.kext is corrupted.  Is there an easy fix?

    Hi,
    I received an EPSON Printer Software Update (vers 2.18) on 30 Aug 2014 and I have not been able to print docs since.
    I received the same Update on 20 Sept 2014 but the result is the same.
    Whilst these updates were being downloaded an error message described the fault lying in the /System/Library/Extensions/AppleUSBEthernetHost.kext
    Is it possible that EPSON has corrupted my Apple drivers?
    George.

    The error is caused by the iTunes update. Delete the kext file, download and install iTunes from the Apple web site, it will re-install a new kext file.

  • "/System/Library/Extensions/WKClassicNotSeizedDriver.kext" was installed

    This message has appeared after doing my second software update. First after 10.6.1 update and now after iTunes update.
    I have no idea what is this about. I do not know which software could be related to this "WKClassicNotSeizedDriver.kext”. I have read the forum and I found a topic with similar problem but related to another software, and explained helpfully by Kappy. I will do the same procedure and see if it solves.
    If someone could help me with this small problem, I will be very grateful.
    Thanks in advance.
