I just did an update to iTunes v11.4, it installed but when the update was over I got a pop up window (Yellow triangle w/ exclamation point) titled:
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.
I went to my Library Folder --->Extensions Folder to see this:
Extensions
ArcMSR.kext
ATTOCelerityFC8.kext
ATTOExpressSASHBA2.kext
ATTOExpressSASRAID2.kext
CalDigitHDProDrv.kext
EPSONUSBPrintClass.kext
HighPointIOP.kext
HighPointRR.kext
PromiseSTEX.kext
SoftRAID.kext
I would think it's related to the new iTunes update, but that seems to be done & no indication to re upload that. I don't understand how to reinstall it and who is the products vendor?
I don't see the "AppleUSBEthernetHost.kext" extension in the Extensions library to begin with. Or, do I just copy it and paste it there?
TIA

EDIT::
-----------------------------
I can't believe I'm the only one on this forum with a mac who has downloaded the update to iTunes (11.4) and had this problem. I have surfed a number of other mac forums and this is the "Hot" issue of the day! This is on Apple support but of course ignored with no advise as what to do.
Really, no one here has had this problem? Wow! Guess this isn't the forum to ask help on...
