Mac device with Chrome OS Flex boots to blank screen


Apple Mac device fails to boot after installation.


Chrome OS Flex's certified models list includes a number of Apple machines. While they usually work as detailed on that list, you may see an issue where installation successfully completes but then a significant or indefinite delay occurs, with a blank screen showing on the device, during subsequent attempts to boot Chrome OS Flex.


  1. Manually set a default boot option.
  2. Clear logic board RAM.
