CNQL1212_ClassicNotSeize.kext" was installed improperly and cannot be used.
Hi
I've had the following message appear -
The system extension “/System/Library/Extensions/CNQL1212_ClassicNotSeize.kext” was installed improperly and cannot be used. Please try reinstalling it, or contact the product’s vendor for an update.
It only happened after I removed, using the uninstall tool, Sophos from my MacBook Pro. I removed Sophos as it was not working correctly on my new MacBook Pro (though did work on the previous (older version) MacBook and reinstalled from the Sophos site. Still had problems (it spends forever 'calculating' when asked to scan the Mac. I've given up on Sophos and now use Avast.
I'm using OS x V10.9.4 with a 2.5GHz Intel Core i5 processor and 4GB 1600 MHz DDR3 memory
Appreciate guidance on resolving this 'error'
CNQL1212_ClassicNotSeize is an old kernel extension for Canon printers that is no longer compatible with—or needed for—Mac OS X. It has no connection to Sophos.

Please help. Is there a update or how do I reinstall?
Thanks,
JohnI submitted the above question, later finding that it has been answered by Buller already. No one need reply as Buller's answer seems to solve the problem for others, and I'll try that.

I get this message often when updating things. I have told Small Dog Computer where I buy my stuff, and they didn't have an answer. Thanks in advance.
What does this mean? ... System extension cannot be used ... The system extension "/System/Library/Extensions/IOFireWireWDHID.kext" was installed improperly and cannot be used. Please try reinstalling it, or contact the product's vendor for an update.Interesting ... thank you! Actually I had that external drive, Western Digital, a while back on my second last? or third last? laptop ... the external drive died with a slew of pictures I had carefully uploaded to it :-(
I won't worry about it anymore :-)
sorry you got only 5 points, can't figure how to give you 10 points. -
...AppleACPILPC.kext" was installed improperly and cannot be used
I've recently been cleaning up my machine after upgrading to leopard. I've fixed most issues but this is still a problem:
every time I start up, I get an error box with an orange triangle exclamation point and this message:
The system extension "/System/Library/Extensions/AppleACPIPlatform.kext/Contents/Plugins/AppleACPILP C.kext" was installed improperly and cannot be used. Please try reinstalling it, or contact the product's vendor for an update.
I was going to do a re-install, but since I've already upped to 10.5.1, it didn't give me the upgrade option, and I'm not sure I should try another way. Especially since this is the last of about 11 of these boxes which still appears, the rest of which I've been troubleshooting individually.
I did search my loepard install for the extension, and replaced the one in my system folder with the disk's version, but I still have the problem.
I don't know if this is causing any real trouble, but I do have one major problem to resolve, to which this one may be contributing, so I'd like to resolve this, or at least hear that it doesn't matter.
the big problem is that my Access Virus TI keyboard isn't recognized half the time and even its AU plug "virus Control" can't communicate with it.. even the software installer (during re-install) can't communicate with it!
But I'll post that elsewhere.
Please, if someone could help with the extension issue, I'd really appreciate it.
Thanks
DanI get the same message
I have been trying to resolve an issue with my upgrade where I have to enter a password to do anything with the files on my desktop. I followed an apple procedure to reset my admin permission [which did not work], but now am getting the same message as you plus one for
/system/Library/Extensions/IONetworkingFamily.kext/Contents/Plugins/Appleyukon.k ext
When I track it down in the finder, the "IONetworkingFamily.kext is not a folder as far as I can see so cannot ft to the contents, etc.
What are these things? What happens if they are not installed and how do I fix this since I do not want to reinstall either. And what is a "Kext"? -

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

I'm still with you, just having a hard time wrapping my mind around the fact that you reinstalled OS X, which is like shooting a mosquito with a cruise missile, yet the problem remains.
Here is the KB article for your review: Reinstalling Mac OS X
Admittedly there is not much to it, but it should have eradicated the problem.
I would guess that the 17 "hp_" messages have something to do with Hewlett-Packard and in fact I do use an HP printer with the computer. I uninstalled the printer software and reinstalled it. The printer seems to work fine, but the kernel extension error messages still keep appearing. I'm inclined just to delete these 17 kernel extensions and then, if the printer doesn't work correctly, unintall and reinstall the printer software again. Sound sensible?
It certainly does. The only thing I can think of is that the OS reinstallation did not recognize those kernel extensions and left them untouched, AND the HP uninstaller did not remove them, AND the HP installer did not perform correctly. Having suffered through several HP botched software attempts I tend to believe that remains a posssibility.
If you are so inclined, I would remove the troublesome .kext files as you say, then reboot. Be prepared for the printer to stop working, but once you remove them try the printer again anyway. The vast majority of printers do not require any specific downloads since their drivers are already built into OS X.
As a last resort try reinstalling OS X again (I know...) and run Software Update to bring everything up to date. Apple released some new printer drivers a few weeks ago.
Finally, if this doesn't work post the same question as a new topic since I am out of ideas. A new topic will get more attention than unresolved questions with responses. -

The system extension “/System/Library/Extensions/CDSDAudioCaptureSupport.kext” was installed improperly and cannot be used. Please try reinstalling it, or contact the product’s vendor for an update.That is a third-party extension, so I would reinstall that software unless you wish to try repairing the permissions on the extension yourself using the Terminal.

When installing iPhoto 9.2.1 software update, I got this pop up.
"The system extension “/System/Library/Extensions/IOFireWireWDHID.kext” was installed improperly and cannot be used. Please try reinstalling it, or contact the product’s vendor for an update."
Is this a minor matter that can be ignored? Any suggestions on what I should do?The faster (and way more recommended) way to do this is to run a permissions repair from disk utility.
Open Applications -> Utilities -> Disk Utility -> Click on Macintosh HD -> then in the right pane there is a "Repair Disk Permissions" button click on this. It should repair all permissions to their proper settings.
Another option is to manually repair them on this kext only. This involves opening Terminal and running the following commands.
sudo chown -R 0:0 /System/Library/Extensions/IOFireWireWDHID.kext
sudo chmod -R 755 /System/Library/Extensions/IOFireWireWDHID.kext
Otherwise if you don't have any firewire devices it doesn't really matter. -
Please help!

System extension cannot be used
The system extension “/System/Library/Extensions/IOStorageFamily.kext” was installed improperly and cannot be used. Please try reinstalling it, or contact the product’s vendor for an update.Could be many things, we should start with this...
"Try Disk Utility
1. Insert the Mac OS X Install disc, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu at top of the screen. (In Mac OS X 10.4 or later, you must select your language first.)
*Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*
3. Click the First Aid tab.
4. Select your Mac OS X volume.
5. Click Repair Disk, (not Repair Permissions). Disk Utility checks and repairs the disk."
http://docs.info.apple.com/article.html?artnum=106214
Then try a Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.
(Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.)
If perchance you can't find your install Disc, at least try it from the Safe Boot part onward. -
Anyone find a fix for this? Most programs installed invoke this error.
The system extension “/System/Library/Extensions/ZD1211Mac.kext” was installed improperly and cannot be used. Please try reinstalling it, or contact the product’s vendor for an update.That driver appears to be for a Zydas wireless usb adapter. Zydas has been through a couple of different acquisitions and no updates appear to be available, so you'll probably need to delete that extension.

The system extension “/System/Library/Extensions/WkClassicNotSeizeDriver.kext” was installed improperly and cannot be used. Please try reinstalling it, or contact the product’s vendor for an update.
thanks for the helps.Need to google WkClassicNotSeizeDriver.kext to find out exactly what this is but I don't think it's an apple kext so remove it.
/System/Library/Extensions/WkClassicNotSeizeDriver.kext
After removal reboot. That reboot will take a little longer since the kext cache needs rebuilding.
Update:
Google search found the following thread:
WkClassicNotSeizeDriver.kext ??? under 10.6
Googling "WkClassicNotSeizeDriver.kext" didn't turn up anything really definitive as to where this really came from but it did show others have seen that same kext. Just trash it.
