Installing Big Sur on 2017 MacBook Pro screen is frozen on the start up window.

After downloading Big Sur on my 2017 MacBook Pro to update the Mojave system, and starting an install the screen has frozen with the Apple start up screen and white bar at 95%. I tried doing a Disk Utility to check for errors and to repair the start up disk, no errors were found. I then tried reinstall macOS, with the option to reinstall Big Sur and after a few hours I ended up with the same frozen screen.

A Safe Mode boot deletes system caches that might help.

Instructions here > Use safe mode to isolate issues with your Mac - Apple Support

As soon as your Mac has booted in Safe Mode restart your Mac.

Thank you this solved my issue, in safe mode it was really slow to key in the set up options but have now restarted the macBook and it is working like a dream. Am grateful for your assistance as it is a work one and I was attempting to reboot and set it upas new for a new person. :)
