I bought a new mac (macbook pro 15’ mid 2014). I connected my exiting external drive. And the new mac was not able to list the drive, and crashed/froze the finder.
If I reconnect my old macbook it’s works perfecly.
Hi dire2000, welcome to the WD Community. As a troubleshooting step be sure to connect the Passport directly to the USB port on the Mac that is having problems, avoid using USB extension cables or USB hubs.
