My Passport for Mac not showing

[elizanvisser]

I’ve just bought a brand new My Passport for my Macbook pro (currently on 10.10.2 OS X Yosemite), but after plugging it in, it does not show up anywhere on the computer - not on the desktop, in Finder or even in Disk Utility.

Where/how can I find it so that I can use it?

Thanks

Hi elizanvisser, welcome to the WD Community. be sure to connect the Passport directly to the Mac, avoid using USB extension cables or USB hubs. If the problem continues try connecting the Passport to another Mac if possible.
