My Passport Ultra wont show up on my Macbook

So basically my passport shows up on my iMac, and works perfectly normally, however does not seem to show up in any way on my Macbook air. Is this a formatting issue, or is this another problem.

My Passport is formatted to ExFAT.

As well the LED light is on when it is plugged in, and the fan is working.
