My Passport for Mac Help Needed

Basically i’ve bought a 500GB My Passport for Mac with the intention of shifting all of the data off of my PC and onto my new Mac but the PC wont acknowledge that it’s been plugged in!

Any Ideas??

Cheers

Is your old PC Windows? If your new passport is formatted for Mac Windows won’t be able to use it. Need to know for sure about the OS on old PC and verify that the Passport is formatted for Mac to help.
