USB3 not working on my Retina MBP

Is this a USB powered drive? It doesn't have it own AC power adapter? If that is the case the Mac is not suppying enough power to it for it to work correctly. You need to get a Y USB cable that connects to 2 USB port on the Mac to power it properly. It should then work and at USB 3 speeds.

USB powered pulls from the power supply, and USB 3.0 uses more power than 2.0.

Use a powered-hub, which can be had for as little as $25.

You won't get Apple to weigh in here. Can you go to an Apple store and seek assistance?

You have 14 days to return the MacBook if it doesn't meet your needs.

Is there a Thunderbolt<>usb adapter that would power your HD?

Maybe with the new Macbook it is time to move to a Thunderbold HD.

:/ Well this certainly puts a damper on things. I hate, with a passion, having to plug in all these extra little wall warts and whatnot, and really makes things quite useless when im out in the field and need to be able to draw off the mac. Id rather step down to USB 2 speeds than have to use another plug. Id love for someone from apple to weigh in on this...

Then get a Y USB cable. The Retina MBP has 3 USB port on them. You would use 2 of them for that drive. If you needed more then 3 then you get a regular 4 port USB HUB to plug into the other USB port.

At multiple hundreds of dollars for a TB hard drive I really don't think that is an option. All that is needed is a Y USB cable. That drive will work.

My new MacBook Pro with the Retina Display arrived a couple of hours.'

After setting it I have now tried 3 diffrent USB 3 Portable hard dives and each one is slower then USB 2.

There must be some sort of problem with USB 3 with these new Macs.

I am very dissappointed at this time.

Ant ideal what gives with USB 3 with the MacBook Pro?

Are you using the required USB3 cable? It has more contatcts and more wires that USB2.

Have you applied the Software Update for the retina MacBook pro? it was just issued a few days ago, and won't be on your Mac unless YOU updated to it.

Sure am using the USB 3 Cable and did all the updates when setting up this new Mac.

The update was nearly 1.3GB,

Look at your device using:

About this Mac > ( More Info ) > USB ...

... and select the exact device if listed. If not listed, suspect Power issues. Check its status -- some devices require drivers, which may not be available yet.

Heres the info on one of them. Looks like it sees it as a USB2 and not USB3:
