Reloading systems extensions

I have the following warning: “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.” How do I accomplish this?

What system extension?
If it is an official Mac OS X extension, then you may need to re-install Mac OS X over top of the existing install.
I suppose if you have a backups, you can get a copy from the backup.
If it is a system extension from a 3rd party, then you should check with the 3rd party for installation instructions.

    Hi Kenneth, depends which version, if less than 10.7/Lion then You need your Original Install Disc.
    If 10.7.0 or later...
    Bootup holding CMD+r, or the Option/alt key to boot from the Restore partition.

  • "System Extension cannot be used" when starting Parallels

    I'm using Parallels Desktop 4.0 to provide a platform for Windows XP on my MacBook. It works very well, but since a recent update of the package, I have been getting a message on startup which says:
    "System extension cannot be used
    The system extension "/Library/Filesystems/fusefs.fs/Support/fusefs.kext" was installed improperly and cannot be used. Please try reinstalling it, or contact the product's vendor for an update."
    I see from other discussions in this forum that this type of warning sometimes appears, but what does it mean generically - does anyone know? So far Parallels support has suggested a couple of things including reloading MacFUSE which I'd never heard of, but they are now suggesting it's a Mac OS problem. Could it be? I need some kind of steer as to what this means and what could have caused it

    Hello MaxGraphics,
    You both may want to read this article before proceeding. It does give you an idea about kext files and how to handle them.

  • HP Laser Printer message saying "System Extension Cannot Be Used"

    I am trying to install a laserjet printer but while it was installing, a message came up which read, "'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." We tried the printer out and it seems to work, however, the scanner does not work.
    When I got this Mac Book Pro, 4 or 5 years ago, I had a HP inkjet printer which I can never use the scanning feature because it did not work. I don't remember what the error message was, but it never worked when I tried to use it. I wonder if the problems with scanning have to do with this particular file that is supposedly installed wrongly.
    We tested the printer out and it worked fine. But no scanning. It can't find the scanner.
    My computer is Mac OS X - 10.6.8. The printer is HP Laserjet  Pro 200 color MFP.
    Anyone have any idea what I should do to fix this error? Thanks.

    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 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 :
    System extension cannot be used
    The system extension “/System/Library/Extensions/System.kext/PlugIns/Unsupported.kext” was installed improperly and cannot be used. Please try reinstalling it, or contact the product’s vendor for an update.

    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.

    how do i reload OS X Server on Mac Mini, App store says installed but no reset or reload, system tells me to reinstall?

    Reboot holding down the Command and R keys.  This will get you in to the Recovery partition.  From there you can reinstall the entire OS.  Please note, Server.app will not be included in the reinstall.  You will need to log into your App store account to download it.

  • Is there an jdev ARCS (appl. revision control system) extension available ?

    Is there an ARCS ( application revision control system ) extension available for Jdeveloper ?
    Googling took me to OAF developer guide which said -
    "With the ARCS (Applications Revision Control System) Extension for JDeveloper, you can perform most
    source control tasks without leaving JDeveloper. For additional information about enabling and using this tool,
    see the E-Business Suite Application Development Services ARCS Extension for JDeveloper web page."
    Can someone point me where to look for this page ? ( I am in Oracle Intranet, so it is accessible for me even if it is an internal page )
    Thanks

    Hi,
    source code control is through Subversion (recommended). For more read up about Team Productivity Center - http://www.oracle.com/technetwork/developer-tools/tpc/overview/index.html

  • What is this error message about, "The system extension "/Library/Frameworks/PrivateTunnel.framework/Versions/Current/Extensions/tap.ke xt" was installed improperly and cannot be used"?

    It appears as a window with the following text, "System extension cannot be used.  The system extension “/Library/Frameworks/PrivateTunnel.framework/Versions/Current/Extensions/tap.ke xt” was installed improperly and cannot be used.  Please try reinstalling it, or contact the product's vendor for an update."
    I close it by clicking "Ok", and it doesn't seem to affect the system performance in any way, but it's annoying knowing that it's there.  The problem is quite old, and has persisted through several OSX updates.

    hello,
    I have the same problem. does anyone have any ideas on what's going on and or how to fix it.
    Thanks!!

  • I keep getting an error message re: System Extensions

    Almost every time that I run Software Update or when Norton runs its automatically scheduled scan, I keep getting an error message saying, "System extension cannot be used. The system extension "/System/Library/Extensions/IomegaSAM.kext" was installed improperly and cannot be used. Please try reinstalling it, or contact the product's vendor for an update." I've also been having problems with Safari, in that when I've had a browser window open for a while and use it to go to different websites, etc., after I've gone to 2 or 3 websites it will then act like it's "stuck" and it won't do anything else until I close the window, quit out of Safari, and start it up again. Then it will be fine and work for a while, until it does the same thing...again.
    Are these items somehow related, and how do I fix this?

  • System extension cannot be used, now no AirPort Card Installed?!?!?!?!

    I have had my MBP for some time now and the other day it went into a kernel panic and after having to go through all the processes to recover it including restoring from the time capsule so that it doesn't take over 10 mins to start up an error message came up saying;
    "*System extension cannot be used*"
    "the system extension '/System/Library/Extensions/IO80211Family.kext/Contents/PlugIns/AppleAirPortBrc m4311.kext' was installed improperly and cannot be used. Please try reinstalling it, or contact the product's vendor for an update"
    Now i cant use my airport card at all, it says that there is no airport card installed and I have spent hours on the phone to apple, done the option + command + r + p thing and had to restore my whole system off my TC with the backup disks and all.
    Plz plz plz plz help, i just want it back the way it was, this is so annoying
    Message was edited by: TBlank

    I had the same problem. It happened to me after I updated to 10.5.6. I didn't notice the problem until I rebooted a few days later. I reinstalled the system from disk and then realized that even though it took almost an hour it didn't really install anything. So I deleted the whole /System/Library/Extensions/IO80211Family.kext and reinstalled the system again. This time it worked

    I have done permissions repair at least 10 times in a row and it still comes up with things to repair but is there another soloution?
    Also, It says i have insufficient permissions to get onto my external HD now as well.
    Anything will help...

    I had the same problem. Then due to another unrelated problem I did a file system check in single user mode and this problem too went away. I am not sure if it will also work for you but no harm to try.
    Shutdown, restart by pressing power button. As soon as you hear the chime, press cmd-s. After a while lot of text will roll down the screen, leave the keys. At the prompt, type fsck -fy. Note the space. then hit return. If at the end of the run you get something was repaired, then run it again till you get 'OK'. After that type reboot and you will boot into regular OS X. Then do whatever you did to get this message and see if it goes away.
