What is the difference between “WD My Book for Mac” and “WD My Passport for MAC” External Drives for Mac. Can all, ORIGINALLY, run Mac OS X 10.6.8 ?
Booting from external hard drives is not supported.
The main differences relate to size. The WD My Book family is stationary and uses a power adapter for continuous use while the WD My Passport family is pocket-sized and feeds from your system’s USB port.
They both work the same for direct file management (Copy/Cut/Paste) and Time Machine backups.
Many thanks for your reply, everything clear ! Just one remaining point : can all those drives run on my “old” Mac OS X 10.6.8, including the new serie of MY Book ?
