Trying to reinstall MX882 Canon printer after upgrading to OSX Mavericks. Printer will not print and I get a message "The system extension "/System/Library/
Extensions/AppleUSBEthernetHost.kext" was installed improperly and cannot be used. Try reinstalling it, or contact vendor for update."
What do I do and where is this extension?

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.

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 couldn't find the extension to get rid of it.
In the Finder, follow the path given above: "System/Library/Extensions/AppleUSBEthernetHost.kext" -
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. -
I clicked on ok. The box behind said updates were installed and I didn't have any problems. Is this something that needs attention? Thank you.
If it does cause problems or reappears, go to hard drive level/System/Library/Extensions/AppleUSBEthernetHost.kext and move the file to the trash. Reinstall iTunes 11.4, which should fix the problem.

Error message 'System/Library/Extensions/AppleUSBEthernetHost' not able to print anymore
Possibly the source of the error message is: 'AppleUSBEthernetHost.kext' has not been installed properly and cannot be used. on my Mac Book Pro'13 early '11 is http://download1290.mediafire.com/5u5azohfzhgg/zo22n2u2eml78vc/AppleUSBEthernetH ost, http://www.mediafire.com/download/zo22n2u2eml78vc/AppleUSBEthernetHost - I cancelled the download, but I found it in my downloads.
Resulting that I cannot print any more wired and wireless. Please would you help to fix this problem at short term? Thank you.Hi Domique,
Thank you very much for your answer. Yesterday I moved the file to the Trash and restarted the PC. Afterwards it didn't succeed to print.
Today (at lunchtime) I didn't find the file AppleUSBEthernetHost.kext at all on my PC. I did request a software update, but no updates were available.
I just (at dinertime) solved the wireless printing problem. By adding a new printer (my own printer) and gave it another name (extension of date of today). I did do this also yesterday, but it didn't solve both printing problems at all.
Now I am able to print wireless. I also looked again if the file AppleUSBEthernetHost.kext was on the system. Yes! It was at the right place System/library/extensions/. It's an old file of 16.05.2011.
The wired printing possibility is still UNSOLVED. Please would you help me to solve this problem too? Thank you very much in advance! -
My itunes will not open at all - I repeatedly get the message"itunes library is corrupted...not installed correctly...please reinstall itunes" I have tried opening all my itunes folders but nothing will even open.
Let's try a repair install of iTunes first.
Restart the PC. If you're using Vista or 7, now head into your Uninstall a program control panel, select "iTunes" and then click "Repair". If you're using XP, head into your Add or Remove Programs control panel, select "iTunes", click "Change" and then click "Repair".
Can you launch your iTunes now? -
When I try to reinstall Photoshop Element 13, I get the message "cannot write file". i own the program and I don't want to subscribe to Creative Cloud. What can I do?
This has nothing to do with CC or any of that. You have insufficient user privileges to write files locally on your computer or a technical issue gets in teh way. Since you have not provided any system info or otehr details, we cannot tell you more than that.

After years of no problems I sddenly can't print photos. When I select print I get the message "There are no themes located. Until at least one theme has been installed this feature will be unavailable. What are themes? How do I install them? Why has this problem suddenly arisen?
Re-installing does not affect your Library in any way. You don't delete it, only the app.
To re-install iPhoto
1. Put the iPhoto.app in the trash (Drag it from your Applications Folder to the trash)
2a: On 10.5: Go to HD/Library/Receipts and remove any pkg file there with iPhoto in the name.
2b: On 10.6: Those receipts may be found as follows: In the Finder use the Go menu and select Go To Folder. In the resulting window type
/var/db/receipts/
2c: on 10.7 they're at
/private/var/db/receipts
A Finder Window will open at that location and you can remove the iPhoto pkg files.
3. Re-install.
If you purchased an iLife Disk, then iPhoto is on it.
If iPhoto was installed on your Mac when you go it then it’s on the System Restore disks that came with your Mac. Insert the first one and opt to ‘Install Bundled Applications Only.
If you purchased it on the App Store or have a Recent Mac you can find it in your Purchases List.
