    I have starting getting this error after installing the latest iTunes update v11.4, loads of people all over the net are having this same issue.

    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 can just OK the box and carry on, but I would like to stop it, or fix it.

    Anybody know what this is and how I can fix this, or just wait for Apple ?

    Hello All-

    I had the AppleUSBEthernetHost.kext problem when downloading iTunes 11.4. This is a widespread problem, many forums have addressed it.

    I found help here: https://www.discussions.apple.com/message/26574841#26574841

    See Lanny’s post, I did as he suggested.
    1st- Close iTunes.
    2nd- Delete the system extension “AppleUSBethernetHost.kext” from here:
    //System/Library/Extensions/AppleUSBethernetHost.kext

    3rd- go to iTunes 11.4 download, here: https://www.apple.com/itunes/download/
    click on the Download Now link.

    4th- Find the downloaded iTunes11.4.dmg file, open it, now open the Install iTunes.pkg

    After the re-install as above I got the successfully installed window and no “pop up”
    improperly installed AppleUSBMultitouch.kext warning window.

    Somebody just posted this over on Apple -

    I just tried the procedure Rhobes posted and it didn't change anything...
    iTunes still will not open/hangs up,
    Console shows the following:

    9/11/14 10:58:03.000 AM kernel[0]: hfs: unmount initiated on iTunes on device disk1s2

    9/11/14 10:58:05.921 AM xpcproxy[836]: assertion failed: 13E28: xpcproxy + 3438 [D559FC96-E6B1-363A-B850-C7AC9734F210]: 0x2

    Yeah, I got it when the install completed. So far, I can't see any further problems--iTunes seems to work OK. If the message pops up again, I'll try the procedure outlined above.

    OK, this morning I went for it and followed your instructions above.

    So far so good, I also got the successfully installed window and no “pop up”
    improperly installed AppleUSBMultitouch.kext warning window.

    Will wait and see what happens after a reboot, cannot do that at the moment as my machine is working on something.

    EDIT: Reboot now done and all now seems OK, with no error message appearing, thank you for your information and guidence.

    No more Apple updates for me for things I do not require.
