Firmware Updater Failure on Mac

Firmware Updater for My Studio II fails.  It correctly identifies S/N and successfully downloads.  Upon entering administrator password, the device ejects, followed by the failure error message “Unable to find device to update”.

When having issues with an update we recommend to stop attempting the latter since you could damage the drive.

What’s the model number for the My Book Studio?


Am trying to update WD Firmware and Driver following an OS upgrade to Maverick!
