It happened to me that after executing install-superboot-mac.sh the phone rebooted and gut stuck at the Google boot logo. The phone did not react to anything I tried (pressing buttons, eg. both Volume buttons or one of the Volume buttons and the Power button), disconnecting the USB cable did nothing either. I've reconnected the USB cable and executed /Applications/android-sdk-macosx/platform-tools/adb reboot which did the trick, the phone rebooted and this time normally. And the phone got rooted, the Superuser app was there.
