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.

This response earlier in this thread should help you with the solution.....

I'm certain that it's the "english as a 2nd language", however, I don't see where you identified your operating system version of OS X in your previous posts....I do see that you are on a mid-2010 15" MacBook Pro with 4 GB of ram.

Let us know if the quoted post above is helpful and thank you for joining us here.
