How do I get beta 9 on my Apple Silicon dev machine?

We're having issues with porting our app. We have been checking for software updates and there have been no updates via the normal channel.

I see the Big Sur beta 9 is out and there was a reference to a fix for Apple Silicon.

We have macOS 11.0 (20A5299w) on the machine now.

Is that the latest? If not, how do we update??
Can someone that has the ARM release installed tell me what your kernel is?

We are having Xcode crashing issues.
We are having issues with memory mapping.

Is there an update?
After hours and hours and hours and hours of frustration, I finally TRIPPED over this in another forum post:

Code Block
sudo /System/Library/PrivateFrameworks/Seeding.framework/Versions/A/Resources/seedutil fixup


Now, softwareupdate --list shows an update.

But, no love:

This is maddening.
