Install has been stuck for four hours on the Apple screen, with status bar at 100%...

I tried rebooting and status bar quickly went to 100% and again stuck...

tried to turn on verbose mode (all the ctrl keys and w, Apple key and v or l) and got nothing...

Same problem. 2018 15" MacBook Pro i9 running the latest Catalina beta.

There is a lot of stuff on my MacBook including HomeBrew, Adobe CC, Pulse VPN. Before trying to upgrade I created a new Volume and installed Catalina beta on it and installed Pulse VPN because that is the only thing I really need to work. Then I upgraded to Big Sur. No problem, VPN worked so it isn't Pulse. I thought that would be the only thing to cause problems. Oh well, time to wait for beta 2.

After removing a bunch of apps and their extensions I was able to do the install. Sorry, I didn't keep a full list of the stuff I removed. I haven't done a clean install in 5+ years so there was a lot of cruft. I removed WebEx, Zoom and Citrix among others. I suspect something I removed from /Library/LaunchDaemons or /Library/LaunchAgents did the trick.

Just installed beta 2, it seemed to have finished installing and rebooted

Sent me straight the apple logo screen with the progress bar in the exact same spot as before. . . So this has not been fixed

You can give it a try to uninstall some agents/services, at least for me it was a success.
Can‘t really say what was the reason at the end, because I did uninstall multiple things at the same time.
But at least I have one favorite for you, if you have it installed, Logitech Control Center (LCC).
It was causing issue for me before, so I was giving it a try.
As a starting point, you could uninstall all installations which are associated with an icon from the menu bar step by step.

But of course that is valid only, if your are able to boot in safe mode.

Good luck.

Same here today with Beta5. Mac mini late 2014 booted from an external microSD (worked fine with Catalina). “Progress bar stuck at 5%, not moving even after several hours”: same. Safe mode: I was unable to boot in it (login window, progress bar went up to 100% then stuck there). Erased the disk fully and started a clean install, which elapsed for around 5 hours, now it’s rebooted and showing progress bar stuck at 50%, not moving for nearly two hours now. I think I’m scrapping this until official release.

Stuck in the same place(Install complete, stuck on loading with Apple logo and progress bar at 100%) after installing Big Sur Beta 9.

I've rebooted several times, went into safe mode, removed external drives, ran cmd+opt+P+R, reinstalled Beta 9.

Still stuck.

Just to let you know that I am in the same boat with my new Mac mini, but load bar at around 90% not 100%. Worked fine with MacBook Pro and older mini.
I too need an answer as to how to progress from here.
