We can not discuss beta MacOS versions in these communities. Visit the beta forums to discuss the beta OS.

Read the documentation provided to you when you joined the beta program.

FWIW, asking how to revert to a release version of macOS is not discussing beta versions. And, there is no public beta forum.

My error, I meant pages rather than forum.
