I installed 10.15 Beta on a machine, and decided to roll it back.Various things went sideways and the best option was to wipe the HD and do a clean restore of a backup.The backup fails because the OS installed is 10.14.5 and not the backups 10.14.6 Beta.So I am trying, and so far failing to get the 10.14.6 installed. It seems I need to have Beta program profile installed on the machine. to do it.However without the profile, I get the message I need the machine to be enrolled, but to enroll it I need the profile.A circular bit of tail chasing.Without the profile I can't access any of the downloads I need to reintall 10.4.6, and the restore my back up.How do I break the Catch 22 and install the beta profile without one?Thanks
