It also could be that the extension's permissions were improperly set when it was installed. Try repairing permissions with Disk Utility. If this doesn't fix the problem then it is as V.K. stated - simply incompatible. Just remove it from the /System/Extensions/ folder.

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. -

I won't worry about it anymore :-)

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? -
Hopefully, i can get some help in resloving the issue below. i updated my harddrive at Techserve and have been getting this message evertime i try to install a new software. Help...
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. -

"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. -

What's this?Niel,
I have the same problem after reinstalling OS 10.6.8. I tried adding (do shell script "chown -R root:wheel /System/Library/Extensions/AppleUSBEthernetHost.kext" with administrator privileges) to Apple Script and followed all your suggestions. I have now installed OX 10.9.5 but get the same message. I did not use iTunes, but your message included "If it doesn’t work, throw that item away and then reinstall iTunes." Where do I get iTunes to reinstall? Sorry because I, too, am not a computer genius.
