I formatted my WD500 my book (USB & Firewire 400) for use with my new iMac. It has been working fine for about a year and now I see this error message: he system extension “/System/Library/Extensions/IOFireWireWDHID. kext” was installed improperly and cannot be used. Please try reinstalling it, or contact the product’s vendor for an update. Any help is appreciated.
One quick question, does the same issue happens in a different computer?
