So I downloaded this: It includes the old v2.3.0 AppleUSBEthernetHost.kext, as well as the KextUtil from cVad. Maybe it's not built properly for my machine. I examined the ist for the AppleUSBEthernetHost.kext and saw 7.0, which seemd right. This was after installing iTunes latest, which was 11.1.1. Kernel Failed to load executable for kext. Make sure your kext has been built against the correct headers. The super class vtable 'vtable for IOEthernetController' for vtable 'vtable for AppleUSBEthernetHost' is out of date. I looked in /var/log/system.log and saw the tell-tale signs that the USB tethering was not going to work:Д¬om.apple.kextd Failed to load / System / Library / Extensions / AppleUSBEthernetHost.kext - (libkern / kext) link error.Д¬om.apple.kextd Load failed removing personalities. Basically, it's a more thorough and persuasive discussion of the problems related to AppleUSBEthernetHost.kext that are discussed elsewhere. I used Google Translate to translate the page. The main resource I used for this is here: It was really just gone, and when I clicked +, I could not add it again. In an effort to rectify this problem, I went into Network Settings, and deleted the iphone USB network, thinking I would be able to re-add it. Maybe it will save some other people some time.ДЄt some point, I don't know when exactly, maybe after installing itunes 11.0, USB tethering stopped working. I have read that perhaps with earlier versions of OSX the USB went the otherway, but I have never gotten it to work, and I highly doubt Apple would have taken that away, as opposed to adding it.ДЄfter several hours of effort, I thought I'd contribute my experience.

However, as long as you have an ethernet connection and a Wi-Fi on the Mac, you can share FROM the Mac to the iPhone via Wi-Fi, essentially setting up a Computer-to-Computer connection between the Mac and the iPhone (or, in more modern terms, the Mac becomes a hotspot). Perhaps Apple is readying the ability share the other way via USB, but it isn't there, yet In reality you can only share this the other way, ie, share internet from iPhone USB TO the Mac. The iPhone USB will appear and from the Internet Sharing standpoint, it will actually allow you to select 'from Ehternet to iPhone USB' but, it doesn't actually work. Go into the Sharing on the Mac, and go to Internet Sharing. Turn on the Personal Hotspot on the iPhone.Д¬onnect your iPhone to your Mac via a USB cable. Make sure the iPhone 'Cellular Data' is active (it will be unless you phyiscally turn it off, like, for testing). Here is the reality that I just discovered. I have a Verizon iPhone 4 (no S), running iOS 5.1. I had this issue, and I have a Mac Mini running Lion that I just installed a week or so ago.

Reinstall iTunes (in our case 10.6.3), this also installs the good AppleUSBEthernetHost.kext: download iTunes from and run the installer, this will install the correct AppleUSBEthernetHost.kext.Restart (not sure whether this is necessary).In Terminal: $ sudo rm -r /System/Library/Extensions/AppleUSBEthernetHost.kext # to remove.The cause is a faulty /System/Library/Extensions/AppleUSBEthernetHost.kext, though the version 2.3.0 is correct, its size of 78 KB, 60.892 bytes is not.ДЄ known to be working AppleUSBEthernetHost.kext for iPhone USB tethering is version 2.3.0, but 225 KB, 189.646 bytes. Over here the iPhone USB interface in the Network pane also keeps displaying 'not connected' when the USB cable is connected to the iPhone.
