        When I attempt to upgrade, I get the following error about halfway through the install:

         

        "Could not create a preboot volume for APFS install."

         

        I have attempted to upgrade twice with the same result.

         

        Is there any way to re-install MacOS Mojave to a machine with Catalina beta installed?
