Installation

Warning: Rooting, unlocking, or flashing your Glass voids your warranty and can leave your device in an irrecoverable state. You will no longer receive OTA updates if you unlock or root your Glass. There is no guarantee that you will receive OTA updates even after flashing back to factory specifications. Proceed at your own risk.

fastboot on MacOSX has some trouble and doesn't work.
Please set "adb" and "fastboot" commands and do path settiings on Linux.

$adb reboot bootloader
$fastboot oem unlock #You have to type this command twice.
$fastboot flash boot boot.img
