The next time I looked at the MacBook Pro screen, it was black except for a progress bar that didn’t seem to be making any progress. I did so and then followed the prompt to log into iCloud. During the installation process, my MacBook Pro restarted several times, and at one point, I was asked to log in. This all happened while I was upgrading the MacBook Pro to macOS 10.13 High Sierra beta 8. Update: Ma– This tip also applies to 2018, 2019, 2020 MacBook Pro with Touch Bar and 2017, 2018, 2019, 2020 MacBook Air With Touch ID models. Fortunately, I was able to figure it out, so I thought I’d pass along this tip to readers of the Rocket Yard who might also run into this situation.
I have a very embarrassing admission to make: after 33 years of being a Mac user, I was completely stumped when I recently tried to force quit and restart my 2017 MacBook Pro with Touch Bar.
