Can't download public beta

[Middleman]

It boots fine in 11.4, but I can't even download the beta.

Uncheck or disable the BlacklistAppleUpdate key in the EFI. That should fix it.

There is a direct download link, the downloaded InstallAssistant.pkg is simply unpacking the Installer to Applications Folder.

You can then double click the Installer to Install on USB SSD for Clean Install and Testing.
