Mojave install is stuck
My 2016 MacBook Pro
Last evening tried to install Mojave. After hours saw that it just had a black screen with an Apple and a white bar. The bar looks like it's showing completed progress.
Let it sit overnight. No change.
Tried to restart holding shift. No change
Tried command R
First time asked if I wanted to continue to install. Yes. Got the same black screen
Second time asked if I wanted to install. Yes. same. Later just all blank with only the arrow - which moves from the touchpad.
Briefly, the mouse moved the arrow.
After a command R did First Aid. all ok and then tried to install the system from Time Capsule but apparently, I never backed the system up.
All attempts did involve waiting a long time to give it a shot of working.
MacBook Pro TouchBar and Touch ID, iOS 12.0.1
