A search of the Toshiba website offers little more than that and in reading some of the reviews Mac Buyers who discover the incompatibility are sending them back for the more expense pre loaded Mac versions- don't do it! It's actually quite simple to reformat- ignore the person who wrote that it took him nearly 20 hours to reformat! It took less than a minute and I'm not that tech savy.ġ. I had forgotten, however, that these ship formatted for Windows 7- with the detailed explanation 'Reformating required for Mac Users'. I have an identical one for my iMac and love the idea that I can just drag and drop files in there outside of my operating system without eating up the internal memory of the machine.

I wasn't interested in using it for backups but that is certainly an option.

Bought this GREAT Toshiba portable hard drive for my MacBook to use to store files, essentially as another drive.
