I think that this is a common issue. I am using My Passport Wireless for the first time on macbook. I can access it fine through wireless connection, but I am not able to use it with USB.
- I have tried changing the the cable, and tried that on another macbook, and still, it doesn't show up neither on disk utility nor finder
- I have tried rebooting (holding power and wireless buttons, while on, for 10 seconds and then waiting until power turns blue and connect, did not work.
. My macbook's OS is Yosemite (10.10.1). One thing to notice is that when I connect it via USB, the power LED keeps flashing, which, according to the manual, means that it is charging.
So, it is charging but not being detected!
Does anyone know what to do with that?
