unable updating to 10.10.14
since the 10.10.14 rolled out I'm trying to upgrade from 10.10.13 but every time I restart to finish installation my MacBook Air 2017 stuck in a black screen with the touchpad arrow in the corner of the screen .
I tried to download it again and reinstalling the update but I end up with the same result. I create a new account with a new user name but same result
MacBook Air, macOS High Sierra (10.13.4), null
