Changing from PC format to Mac format

I want to change My Passport Ultra from PC to Mac compatible.  Is My Passport Ultra compatible with Mac OS X “Yosemite” (sinceit wasn’t listed in the User’s Manual compatability list), or is there a software update to make it compatible with Mac OS X Yosemite?


If you want to use this drive on a Mac computer you just need to format it for Mac.
