Passport PC to Mac use

I have a 1TB Passport used on a PC laptop. I would like to use it exclusively on a Mac. How do I switch from PC format to Mac format?  Thanks.

Hello,

If you are planning to use your drive only on Mac then you may format the drive on your Mac computer.

See if the link below will help.
