Almost everytime I install an update from Apple (and sometimes 3rd party updates or software) I get this notice that a "System Extension Cannot Be Used" - The system extension "/System/Library/Extensions/TabletDrv.kext" was installed improperly and cannot be used. Please try reinstalling it or contact the product's vendor for an update."

Does anyone know if this is an APPLE INSTALLED extension or 3rd party or ??? Can I just go ahead and remove it / trash it and empty the trash?

Thanks for any comments - My MacBook Pro-13" (April 2010) is not a tablet- but perhaps this extension is for use with a tablet?

Best regards,
