System Extension Issue

I keep getting this message on my IMac 7.1 it says:  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. I dont know what this means. Help....?

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, throw that item away and then reinstall iTunes.

  • System extension cannot be used  --can anyone help ?

    so i spotted that the system library as well as the home library had permissions blocked for the administrator, so i unlocked all enclosed items permissions.
    i already had issues being brought to senior advisor attention over 1,5 years now, about hangs and freezes. mostly hangs.
    no one so far has been able to fix them.
    well now spotting these warnings, after i allowed all permissions inside both libraries, have warnings show up.
    i gather these are not prepperly installed softwares, but i cant figure out what softwares they could be, so i can take care of it.
    so 4 warnings shows up :

    There isn't an "administrator" so who did you add and what permissions did you set.
    In Get Info, they should be
    system    read & write
    wheel       read Only
    everyone  read only
    The posix permissions, owner, and group should be
    rwxr-xr-x  root wheel
    with ACE "group:everyone deny delete"
    You may be able to recover by repairing permissions in Disk Utility, but you may have to reinstall the OS.

    I no longer use a Western Digital external hard drive so I am not sure how to remove this file so that I no longer get this message. Can anyone take me through the steps to fix this issue?

    Hello,
    See if the WD Installer has an uninstall function... you really don't need it at all.

    I do not have a copy of the OS X 10.6.8 software. It is second hand so I have no product vendor to contact.
    What can I do?

    You recently updated iTunes to v.11.4? This message has popped up on many a Mac screen when this version was first made available, because this kext was obviously faulty.
    You should try to download iTunes 11.4 again from Apple's website: the new version bears the same name, but this kernel extension has been updated, and the issues it was causing are now a thing of the past.
    Should solve your problem, too...

  • Every time my system updates I get system extension error messages.

    Every time my system updates I get system extension error messges.  It reads that certain extensions could not be loaded/used which seems to be an apple issue.  Unfortunately, unless you have apple care there is no way to contact them.  I am on LION and my updates are current.  Is anyone else having this issue?

    A "clicking noise" is often a sign that a hard drive is malfunctioning. Suggest that you power down the device and take it to an Apple store to have them take a look, or contact Customer Service at Apple for instructions.

  • System Extension can not be used

    I have recently updated iTunes to the latest version. During the installation, a pop-up error message appeared saying "The system extension "System/Library/Extensions/AppleUSBEthernetHost.Kext" was installed improperly and cannot be used. Please reinstalling it, or contact the product's vendor for an update".
    I have tried to reinstall iTunes, but no help. What could this issue and what is the fix ??

    Open Terminal in the Utilities folder. Paste the following at the prompt:
         sudo chown -R root:wheel System/Library/Extensions/AppleUSBEthernetHost.Kext
    Press RETURN. Enter your admin password when prompted. It will not echo to the screen so type carefully. Press RETURN again.
    Restart the computer.

  • Changed Permission Settings: "System extension cannot be used"

    I was having some weird problems with file sharing on my network recently, so I tried changing around some of the permissions on my drives to see if I could resolve it. For some reason I was getting messages saying I didn't have permission to copy files from one computer to another on my network. This seemed to come on randomly as we have been doing file transfers this way for quite some time now. I looked at our file sharing preferences in the System Preference's and added all 4 drives from my Mac Pro in there and made sure that my username had full read and write capabilities. I then tried logging into my Mac Pro from my iMac, just like I've done in the past, and I was still unable to copy the files. So I removed all the folders and turned off file sharing. I then clicked 'Get Info' for my main Macintosh HD and tried changing the permission settings there. I clicked the option to make my username the owner, and then I clicked 'Apply to enclosed items...' and this brought up a progress bar that I let go for about 10 minutes. Then I got a pop-up error message stating "System extension cannot be used" and had an extension path listed underneath, saying it was installed improperly and cannot be used. This happens an endless amount of times. It seems to be giving me this message for every single extension on the computer. If I hold down enter the pop-ups just keep coming with different extensions listed.
    I hope someone with some insight on how permissions work in OS X Lion can give me some advice on how to resolve, and possible the correct way I should be setting up sharing if I've been doing wrong all this time. What strikes me as odd is that I never had any issues with sharing anything up until about a week or so ago, and I can't remember if there were any system updates that I installed that might have something to do with this.
    Any help is much appreciated, thanks!

    I had this problem recently in addition to my laptop getting stuck on the Apple logo and spinning icon. It took me a long to time to work through it so I thought I would share what I did to make it easier for others.
    The best thing to do when having permission problems is to do a 'disk permissions repair'. You can do this using the disk utility app found in your applications/utilities folder. This will attempt to rewrite all the permissions that were incorrectly set. When it is doing this it is common to get a message saying 'ACL...found and not expected...' do not go and delete these files. Its normal for this correction process to take more than 30 minutes, for me it took an hour.
    If this proccess doesnt work for you than you can also try a disk repair.
    If you can't boot using the normal disk you can also access this program through the recovery boot (holding Command-R of Option at startup), through the safe mode (holding Shift on start up) or through a recovery CD. You can also boot in a terminal type mode but this is a last ditch effort as a misspelt command could do more damage. personally, because I do not know what the commands I am using actually mean, I would recommend talking to a person at apple then using this approach.
    Hope this helps

  • N-Mon.kext system extension cannot be used

        Hi all!
    I bought a macbook pro md318.
    In some point, after I used for a couple of days, an error message began to show on a window from time to time
    The message says:
    The system extension “/System/Library/Extensions/N-Mon.kext” was installed improperly and cannot be used. Please try reinstalling it, or contact the product’s vendor for an update.
    Do you know how can I resolve this issue?
    My MacOSX version is 10.7.4
    Thanks a lot!

    The problem is that I go to finder/applications and I don't see any VUZE app installed.
    The only torrent program that I installed is utorrent, wich I uninstalled by dragging the application on finder/applications to the trash.
    Do you think that this might be causing the error?
    thanks for your answers!

    Some exteral FireWire optical DVD/RW+CD/RW drives work fine, but
    may have an issue on attempting to boot the original or third party
    OSX bootable install/restore disc or one otherwise made to boot the Mac.
    This is where it's nice to have a decent return policy at the place of purchase.
    Also, a Mac-Friendly reseller should have someone on their staff, perhaps
    in the service department or an Apple sales specialist who uses Macs,
    who can suggest such an external optical drive to suit your needs for now.
    There are several generally good brands; but I am not sure what ones
    are most likely to do this critical function. For other features that may
    or may not work (such as burning various disc formats, etc) you could
    use shareware or freeware disk burning utilities. I found a few free ones.
    You should be able to possibly use another computer's optical
    drive to attempt a reinstall (archive & install may not fix it) of
    the dysfunctional Mac's OSX to get the suspect extension back.
    [I'm still wondering if the extension itself is the problem. Some of
    the items that show up in a System Log as being bad can be
    worked around by the system, or were items by-passed in a
    system upgrade at some time in the past. A full reinstall may work.]
    There may be another route to take, and suggestions outside
    of these few would be entertained. It would be a BYOB sorta deal.

  • System Extension Cannot Be Used?  How do I fix?

    Hello
    I recently updated to Mavericks using 10.9.4, and installed a Canon Pro 100 printer.  Ever since I did this I am getting the following message.
    "System extension cannot be used
    The system extension “/System/Library/Extensions/IOFireWireMxBt.kext” was installed improperly and cannot be used. Please try reinstalling it, or contact the product’s vendor for an update."
    Also, what is "IOFirwWireMx.kext"?  If I knew what is was, I would try to re-install it, as it suggests.  But I don't know what this is referring to.  How do I fix this?
    Thanks for your help.

    I'm afraid there is no simple solution without a backup of the Mac before 10.9 was installed. There are user tips that explain the process, but it will vary for each user depending on what is used on the Mac.
    Apple: Restoring a previous OS X version
    How to revert OS X back from Mavericks
    I have seen that many users complain about 10.9 being slow/ worse than "whatever was installed before".
    Personally I find it comparable in performance to other OS's.
    The trouble seems to be that users have migrated with many old apps installed from previous OS versions. Old system extensions & other background tasks that can make the OS perform badly. If installed software is not compatible with 10.9 it can cause errors (as the old Maxtor software illustrated).
    The basic options are to clean up the OS (find out how to uninstall all the old stuff) or to reinstall the OS without the old apps.
    The process usually involves creating an EtreCheck report to show people here what is installed. From there you can either decide to backup your data & reinstall or attempt to clean out some older apps (assuming that is what is causing the trouble).
    http://etresoft.com/etrecheck
    It helps if you include descriptions of what the actual issues are, e.g. Finder takes x mins to open folders.
    You will also want to make a full backup onto another disk. Do you know how to do that?
    I'd suggest you mark this thread as solved & then create a new thread so that the topic is clear. Post a link to it from here if you want me & Kappy to see it

  • System Extension Cannot Be Used: Soundflower Error?

    I've had this issue for a long time now and I never knew what started it, it just started happening one day.andomly get
    Anyways, I randomly get this pop up message that says:
    System extension cannot be used
    The system extension "/System/Library/Extensions/Soundflower.kext" was installed improperly and cannot be used.
    Please try reinstalling it, or contact the product's vendor for an update.
    There's no reason or rhyme to when it happens. I think maybe the app Boom that boosts volumes sometimes triggers it, but its never 100%. Also I googled around and I've tried some things like that restart the computer and have it run the system check and it didnt fix it
    If anyone can point me in the right direction on what this might be I'd be very appreciative.

    Open the Script Editor in the /Applications/AppleScript/ folder and run the following:
    do shell script "chown -R root:wheel /System/Library/Extensions/AppleUSBEthernetHost.kext" with administrator privileges
    You may then need to restart the computer.

  • Message displayed: 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.

    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?

    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.

    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.

  • Extension Issues 10.10.2

    Anyone having issues with extensions popping up saying they cannot be loaded.  Keeps happening since update to 10.10.2.

    Post the name of the extension or grab an image of the dialog.
    cmd+shift+4, drag the crosshairs over the dialog, Attach it to the post via the camera icon on these pages.
    Rebooting should cause the dialog to appear if it is a system extension, it may be a third party developer that has not signed the extension, or it could be a damaged Apple extension.
