I have never had this problem before. 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 products vendor for an update. This was the message that appeared after I installed the new iTunes Update for 11.4 today. I have an iMac 2.7 GHz Intel Core i5 with 8 GB memory, I have System 10.9.4 I reinstalled iTunes after removing the AppleUSBEthernetHost.kext and same message. I went back and looked at the previous version in Time Machine of the file and it was the same 7.0. Everything seems to be working okay. Any suggestions are appreciated. The forums had 3 other people write in with no solutions.

I too have the same message popping up on our iMac. I checked the system updates and it updated to 11.4 automatically this morning. Not sure whether I need to do something, everything seems to be working as normal as far as I can tell. Presumably they'll release a fix if it's to do with the update?

As an experiment, I redownloaded iTunes from Apple Site and TURNED OFF my iPad. Turned it off not put it to sleep and reinstalled and all went well. I do not have an iPhone and the iPad is my only extra apple device. There was no message this time and so far so good. Mark

Such bugs (due to apparent lack of attention to detail*) seem to occur every time Apple posts an update. If this one is as widespread as it appears to be, iTunes 11.4.1 should be showing up on their Support-Download site in short order.
* In the old days parsimony, elegance and debugging were the hallmarks of application design, given the pragmatic necessity occasioned by extraordinarily small memory capacity of computers. Nowadays sloppiness in design and lack of efficient debugging seem to be the acceptable rule.

Mark Are you saying there might have been an interaction between your iTunes installation and your iPad? I installed iTunes this morning and did not see that error message. Maybe Apple surreptitiously fixed it in the later install? Your successful reinstallation may reflect this.

Would be useful for all of you to post which version of OS X you're running.
Did all of you who are getting this error install the iTunes 11.4 update beforehand?

Same problem here. The error message just popped up. I cannot think of anything I might have done to cause the problem, and am wondering what the consequences of doing nothing will be.
MacMini running 10.9.4
By the way, has anyone found a solution to the iconservicesagent problem? (I am aware of the workaround (mkdir ...), but am wondering if there is a solution.)

Had the same problem here today with this popping up after installing the update to iTunes 11.4.
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.
OSX 10.8.5 3.06 GHz Intel Core 13 4 GB 1333 MHz RAM
I don't 'tether' anything to my desktop but would still like to know what, if anything, I need to do. Will iTunes still be able to install future updates?

Reply to: cyn
Posted moments earlier but replying to this post again here ...
I have ... Version 10.8.5
... and yes, I installed the iTunes 11.4 update just BEFORE the message popped up. I have checked and so far iTunes is working fine on my computer. Just wondering what, if anything, I need to do and if there will be problems with future updates to iTunes. Thanks so much!

I also had this message after installing iTunes 11.4. I ran my OS 10.6.8 Combo installer and have not experienced any problems since.

Same problem just now when installing the iTunes 11.4 update.
Running 10.7.5 on a 2.4GHz i5 MacBook Pro.
Anyone have any idea what the error means? Otherwise this thread will continue to just be one "me too" after another.

This is the best post I can find: https://discussions.apple.com/thread/6526427I used Pacifist to remove the .kext file from the iTunes install package and replaced the old .kext in the System/Library/Extensions folder. Seems to be working okay on 10.6.8 and 10.9.4.

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#26574841See 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.

Totally agree. Against my better judgment I hit Update on itunes, even though I have no ios8 device. So I had to do the manual remove kext, download, reinstall iTunes. This is the reason I stopped updating my Airport express and any other Apple app that says "improvements" for connection to Cloud, ios, or anything else I do not use. It is not worth the headache to have to fix something that wasn't broken to start out with.

Thanks Robes, that seems to have done the trick for me. I just want to point out to everyone I too had my iPad connected when I first installed the system update from Apple. This time when I reinstalled iTunes I disconnected the ipad first.

Robes 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.
