WD My passport for Mac not working with Yosemite 10.2.2

I have three My Passport for Mav which have been working fine with my Mac Book Air. I recently found that none of them are recognized by my Mac Book Air after upgrading to Yosemite. Anyone has similar problem? How can it be solved? Anyone heard official news from WD or Apple regarding that?

Thanks for any update.

Hi Fatellp, welcome to the WD Community. We have passed this along to support. Have you verified if the hard drives are recognized on the dis utility?
