Fix macOS Big Sur RC update
Raw
gistfile1.txt
The issue is caused by an incorrect software catelog. As apple is releasing big sur thursday, they changed the software catelog to the production one. The problem is that the production one does not yet have the bridge os firmware for big sur just yet. So in order to update right now you need to change back to the devleoper catelog.
