…oading The else branch (LoadingDmg == FALSE) called SetAvailability(FALSE) instead of TRUE, despite the debug log saying "Reenabling secure boot after Apple images". This left Secure Boot permanently disabled for the rest of the boot session after any DMG (e.g. installer/recovery) was loaded, causing subsequent IMG4 verifications to be silently skipped (EFI_UNSUPPORTED) instead of actually performed.
