Message after installing Mavericks
Roy Rainford
After Mavericks 10.9.4 was recently installed on my iMac this message occasionally appears on the desktop:"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 haven't a clue what it means or if I should do anything about it. Everything seems to be working reasonably well as far as I can see. Some programmes running a little slower, as Mick warned and occasional freeze-ups. Nothing really serious. Can anyone enlighten me please about the message? Roy
