Porting our application to beta10 Apple Silicon, we have a small test program that works on Mojave/Catalina (Intel). We haven't been able to install beta10 on Intel because VMware Fusion Pro 12.0.0 doesn't work with beta10.
Here's a run on beta10/ARM:
@macarm[git:master]$ cc -m64	-g -Wall -Werror -o mapfail mapfail.c
@macarm[git:master]$ codesign -vvvv mapfail
mapfail: valid on disk
mapfail: satisfies its Designated Requirement
@macarm[git:master]$ ./mapfail 10000000 10000
maping from 0x10000000 to 0x10010000 is OK
Unable to reserve at 65536 (0x10000) bytes of memory for the test1 heap
test1 not mapped
@macarm[git:master]$
Here's a run on 10.15.7:
@macdev[git:master]$ cc -m64	-g -Wall -Werror -o mapfail mapfail.c
@macdev[git:master]$ codesign -vvv mapfail
mapfail: code object is not signed at all
In architecture: x86_64
@macdev[git:master]$ ./mapfail 10000000 10000
maping from 0x10000000 to 0x10010000 is OK
Unable to reserve 0x10000000 for the test1 heap,
using 0x109c14000 instead
test1 heap mapped from 0x109c14000 to 0x109c25000
@macdev[git:master]$
This has stopped our app porting effort, since this is a basic error that doesn't even allow the app to start up.

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??
We have the mac mini with Big Sur / ARM and wanted to update it. However:
softwareupdate -l
Software Update ToolFinding available software
The operation couldn't be completed. (NSURLErrorDomain error -1012.)
And, we also used System Preferences > Software Update and it says: Unable to check for updates and then no available updates found, please try again later.
We're having stability issues and wanted to update. We're running:
Darwin macarm.local 20.0.0 Darwin Kernel Version 20.0.0: Sun Jun 14 21:36:36 PDT 2020; root:Bridge_xnu-7090.111.5.2~1/RELEASE_ARM64_T8020 arm64
