I had an issue previously where I could not update from beta 6 to betas 7, 8, or 9 on my MacBook Pro (post here: https://developer.apple.com/forums/thread/661453).

In response, Apple released a full download of beta 9 (the full 12.17GB install profile from developer.apple.com). I imagined this would solve my problem, since whenever I re-installed the full beta 6 from "Safe Boot" I was able to run beta 6 without issue (even though I had updates outstanding).

Now, when install beta 9 from developer.apple.com, I get the same issue where my computer will not restart past 80% (I left it sitting for 12 hours, no dice). So now my MacBookPro is only usable in Safe Boot.

I know others were experiencing the same install/update issues that I was - does anyone have a fix?

Further, this seems to only be affecting my late 2018 MacBookPro 15"; my 2017 iMac 21.5" has been updating and running perfectly fine.

@skoskie808 - I haven't tried contacting Apple other than via the Feedback Assistant (no response) or through here. Thankfully I have my iMac which works perfectly on beta 9, and my MacBookPro still boots in Safe Boot (and everything is backed up, from about a month ago with beta 4 or 5 (so at least my photos and hard drive data is "safe")). I would definitely be in a much *much* worse position if my MacBookPro was my main computer/work computer, but thankfully it is my personal computer, so I can live with having it only work in "Safe Boot" for a couple of weeks. REALLY hoping a new beta and/or the GM is released tomorrow or at the Tuesday event...

I believe beta 10 has fixed the problem!!

It may have also been using Recovery mode. I updated to beta 10, but still had an issue and was only able to boot in "safe mode." I then restarted in Recovery Mode (CMND + R). I did a disk utility and the operation was successful. Then I re-installed macOS big sur.

Problem was still not solved, the reboot hung again and I needed to boot in safe mode. However, the re-install re-installed beta 9. I installed the beta 10 update from System Preferences and beta 10 booted up fine!

Running normally now!
