macOS 27 - MDM client removal of AvailableOSUpdate command - Super 5.1.1

[PaRkThEcAr]

Good morning! so i figured it was worth mentioning, but the mdmclient command no longer inclues the AvailableOSUpdates argument as Apple has seemed to split it off in macOS 27's more recent beta builds.

here is a command output.

I am aware... and deep in a near-complete rewrite of super that includes resolution for this issue as well.

It doesn't matter what other strings are supported... this method is going to be abandoned given this:
