Try going into the dev alpha menu (little gear in top right corner). Go to storage & sharing. Set the USB connections to "Connect to ..."
I tried setting the "connect to" to both Windows and Mac, on both occasions, Mac DM stopped detecting the device when I plug it in and doesn't even attempt to connect.

I found that repairing actually didn't update me to the latest OS. It brought me down to 10.0.4.* and now after I've plugged in the device back to my mac it's currently upgrading to the latest 10.0.6.545. Make sure you do that after you're done installing the OS if you haven't already.
