I’ve started the upgrade on my MacBook Pro A1708 at 9pm yesterday night, it’s 7am now and it’s still stuck on a black screen with the apple logo and the progress bar at the same point, with written “Estimating time remaining”.. I tried to switch it off and on but it does the same. What shall I do?
iPhone 7, iOS 13
Sorry that didn't work. Give the following article a try: How to fix a Mac that won't finish a macOS update - Macworld
If that still doesn't help, I suggest that you contact Apple directly by clicking on the Contact Support link in the upper righthand side of this forum's web page.

See if you can boot up your Mac in Safe Mode, and then, try the installation again. Also, try connecting your notebook with an Ethernet connection if it is currently using a wireless one now.
