My Passport Essential SE won't show up via USB 3.0, but will show on USB2.0

My Passport Essential SE won’t show up via USB 3.0, but will show on USB2.0. What gives?? Please help

What I have Tried:

Different cables

Different Macs

Reformatting the Drive with WD Smartware

Reformatting Drive useing Mac Utilitiy


This sounds like a driver issue.

Try uninstalling the drivers for the USB 3.0 and install that again.

Make sure you get the latest USB 3.0 drivers available for your computer.

On a mac? How would you do that? This mac is brand new.


I checked on the apple support site and found this about the drivers.

  • Be sure you’ve installed the latest software updates available for your computer. To check, choose  Software Update  from the  Apple  () menu and see if any updates are available.
