I will likely wait until beta 8 is released to try again (and I am submitting Feedback to apple consisting of this post, basically verbatim), but I was wondering if anyone has any thoughts or if this has happened to anyone else. Except, when I try the software update again (the same 3.61gb update from beta 6 to beta 7) the issue happens *yet again.* Users of macOS Mojave (10.14) and Catalina (10.15) can install it as a standalone update via System Preferences > Software Update. But, of course I have a software update (to beta 7) waiting. Big Sur comes with a new version of Apples web browser, although you dont actually need to upgrade your entire OS in order to get Safari 14. My MBP started up fine and normal on beta 6, and everything works as it did before I ever tried updating to beta 7 in the first place. This actually did a full re-install of beta 6 (20A5364e), since I believe you need to update to beta 7 from beta 6 and can’t do a full install. So, I went to and re-downloaded the beta from there (while in safe mode). I tried rebooting (not in safe mode) and the issue persisted.

I ran a full disk utility in Safe Mode, my computer said it was a success. No issue here at all! Great, however, the computer would only work in Safe Mode. Some changes will be more successful than others, but in a year or two, older versions of macOS will look dated.

MBP wouldn't restart, same issue (getting ¾ through and then freezing + fan).

The user interface changes in Big Sur are a makeover the likes of which we haven’t seen in years, with Apple adding whitespace and trying to prevent the interface from distracting from your content. Did this for *hours* until I cut my losses (I have a pretty recent backup) and held down the power button and shut the computer off. Point 3 - Empty Space Requirements > If upgrading from macOS Sierra or later, your Mac needs 26GB of available storage to upgrade. Install was going fine, until, when my MacBookPro was restarting, about ¾ through the start-up bar the computer froze and the fan started going crazy. So, when macOS Big Sur beta 7 (20A5374g) released last week, I installed it (from beta 6).
