私はkextunloadその後に続くことを考えていましたkextloadが、実際にはうまくいきませんでした：
%sudo kextunload /System/Library/Extensions/IONetworkingFamily.kext/Contents/PlugIns/AppleYukon2.kext
(kernel) Can't unload kext com.apple.iokit.AppleYukon2; classes have instances:
(kernel) Kext com.apple.iokit.AppleYukon2 class sk98osx_dnet has 1 instance.
(kernel) Kext com.apple.iokit.AppleYukon2 class yukon has 1 instance.
(kernel) Kext com.apple.iokit.AppleYukon2 class yukon2osx has 1 instance.
Failed to unload com.apple.iokit.AppleYukon2 - (libkern/kext) kext is in use or retained (cannot unload).
%sudo kextload /System/Library/Extensions/IONetworkingFamily.kext/Contents/PlugIns/AppleYukon2.kext
その後、私はこれを得ています：
%ifconfig en0
ifconfig: interface en0 does not exist
さらに試行するたびにkext(un)load、その状況では何も変わりません。
それを試みている間、私はこれらのメッセージをkernel.log以下で受け取ります：
