EXTENSION Help Get Error /System/Library/Extensions/hpPlugInInit.kext was installed improperly How do I reinstall correctly?
/System/Library/Extensions/hpPlugInInit.kext was installed improperly How do I reinstall correctly? I can never upgrade software because of this error.
Go to that folder and delete that file, then reinstall whatever software it was a part of (probably some HP printer software, I'd guess?).

Hi,
I started receiving the following error message (picture) about a week ago, and it has popped out every day. I have not noticed what triggers it yet.
Does anyone know what could it be and how to fix it?
Thank you!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.

/System/Library/Extensions/hpPlugInInit.kext was installed improperly. How do I fix this? iTunes is no longer working and this is the message that keeps popping up.
First off, you are running an intel not a PPC.
Second have you attached a USB external drive to your computer? Remove all peripherals and see if the message goes away. Then reattach each peripheral one by one to weed out the problematic one. -
System extension hpPlugInInit.kext was installed improperly and printing won't work
Installing the software results in non funclltioning or poorly function printer on both of our macs. Each computer has a printer. I get a message that "System Extension cannot be used. "/System/Library/Extensions/hpPlugininit.kext" was installed improperly and cannot be used. Please try reinstalling it, or contact the products vender for an update.
An Apple repair shop 60 mi. away didn't seem to have much problem getting one computer fixed today. I reinstalled the software and the printer printed today. I started the set up with a cable connection and then the printer wanted to go wireless. It printed but only did one side of a page. I haven't had the printer for very many months and it did do two sided printing and everything else. I think the problem may have started after an Apple software update. I cannot delete the damaged software. It is protected from my messing up the software.
This computer will go to the shop Thursday morning if I can't fix it before that.Hi,
click the Finder icon, then click the Go menu and select Computer.
Select your active boot volume, will usually appear as Macintosh-HD.
Browse to System > Library/Extensions and type hpPlugininit into the search bar, select to search in the Exxtensions folder and move the hpPlugininit.kext file to the trash.
Empty the trash, then reinstall the latest driver below:

Note: Be sure to check the HP Scan option to get full functionality.
Please let me know if that helps,

Please help me.Darned drivers. Did you try using it without the drivers? They may already be in Mountain Lion. I'm super wary of vendor drivers for OS X; they're terrible and often an OS version out of date.
To re-install OS X, log into the Mac App Store, go to "purchased," re-download Mountain Lion, and double click "Install Mountain Lion" as you did the first time. You won't lose data (have a backup!) and an hour later you should be good to go.
After that, try using the printer WITHOUT installing the darned Lexmark drivers. -
I received this error message: The system extension "/System/Library/Extensions/ACard6280ATA.kext" was installed improperly and cannot be used. Please try reinstalling ... . What is this about? What is ACard6280ATA.kext?
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. -
While running the Software Updater, I encountered an error: "System Extension cannot be used" ... System/Library/Extensions/AppleUSBEthernetHost.kext was installed improperly and cannot be used. Can somebody help me resolve this error message. Would this error affect my ability to run FaceTime ?
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. -

Right. -
Was updating at the App Store - Safari, iTunes, iWorks 09 and prior to that had updated something at Adobe's website. Then this error message popped up:

(I just received a refurbished computer with a new hard drive from a local Apple repair store...
Is this an easy fix. Thanks, CharlotteWhat I ended up doing is a reinstall the OS.
There was an important component I forgot to mention...my hard drive had crashed and I had it replaced. When it was replaced - the old drive was copied to the new. Since the prior error messages I had gotten from MemTest and CheckMate kept saying Bad Blocks in the drive - it was suggested that the corrupt or missing data on these "bad blocks" had not copied or copied incorrectly.
So only time will tell if this fixed this error. (Don't have external hard drive so never had Time Machine set up to begin with.) Original computer was refurbished and believe some things weren't done right from the get go. Oh well... Hope I didn't lead anyone astray.
