Noticed on the restrictions payload in configuration profiles that Media Restrictions are listed as deprecated after macOS 10.15. Does anybody know if there is an alternative method for blocking external drives in Big Sur?
@glennmiller so Apple did not announce this deprecation at WWDC last year with Big Sur (or I missed it), and it was marked deprecated at the Big Sur release. I have an open FB ticket with Apple posted above. If you have any sort of AppleCare support agreement I would suggest opening a ticket and referencing my FB ticket. I have supplied a lot of data to it, but Apple has pretty much ignored it.
I think that driver kit and system extensions will probably replace this functionality, but media restrictions are highly broken in big sur and less broken in catalina and mojave, but I have been able to reproduce this issue all the way back to mojave. I did not test any further before Mojave though.
