Heartbeat but USB connection to computer not working.

I just purchased a BeagleBone Blue. I initially plugged in into my laptop over USB, installed the drivers, and it showed up as expected. I made sure it was alive and working, looked at the readme.htm and then disconnected it. Later that day I plugged it back in and now it won’t ever connect to my laptop. I’ve reinstalled the 2 Mac drivers for my laptop but still nothing. No wifi either. The only thing it appears to be doing is flashing the USR 0 LED, which I believe is the device’s heartbeat.

Any ideas for options to try to get it to connect?

Any help would be greatly appreciated, was really looking forward to using this board on a couple projects.
