HT201628 it didnt change any for me, and its keeping a pop up that says " /system/library/extension/USBExpressCardWake_Huawi.kext installed incorrectly or so"
and it cant recognize my ipad via itunes, so whats next?
Well, if you are using DoNotTrackMe and you don't have this issue, then DoNotTrackMe must not be the cause.
But I would really rather not turn off Little Snitch entirely, if it is the cause of this issue, because I know from experience that Litel Snitch does prevent hidden background connections that I don't want to happen and that I otherwise would not have known about.
Is there a way to adjust Little Snitch's parameters such that it allows most "normal" and "expected" Web page connections and only alerts to sneaky hidden connections?

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. -

What do I do and where is this extension?beverly216 wrote:

I would recommend you download and install the OS X 10.9.5 Combo Update.
That file is part of the operating system and it is located where the error shows, i.e. HD > System > Library > Extensions. It would seem that when you updated, this file and maybe others have not updated correctly. So running the Combo Update may help resolve this. -
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. -

I have a MacBook Pro running Mas OS X Version 10.7.5
Is this a problem I need to fix? Is there a fix or update? -
What does this message mean ? It has popped up a couple of times and I want to fix whatever it is. Thanks for your help.
Seems pretty clear to me. Here's what you can try:
Open Terminal in your Utilities folder. Paste the following at the prompt:
sudo chown -R root:wheel /System/Library/Extensions/AppleUSBEthernetHost.kext
Press RETURN. Enter admin password when prompted. It will not be echoed so type carefully. Press RETURN again.
Restart the computer. -
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? -

The system extension “/System/Library/Extensions/CDSDAudioCaptureSupport.kext” was installed improperly and cannot be used.

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.
