Do you get the warning with just the cable plugged in to the Mac? (i.e. not connected to the Pi)

What else do you have connected to the Pi? The warning usually means some device is trying to draw more than 500mA from the USB port. The Pi alone will be pulling 450 or so by itself during the boot. If the USB poly-fuse trips, sometimes it takes 10 minutes or more for it to reset.
