MacBook Pros and (their lack of) DisplayPort MST (Multi-Stream) support: what about macOS Catalina?

Old point: Daisy-chaining two USB-C displays on a MacBook Pro (2016, 2017 models).

So far it won't work with MacOS X (including Mojave) as MST is supported. Sadly it works even with a Bootcamp Windows?


New Question: what about macOS Catalina? Any changes regarding MST support?


MacBook Pro 15", macOS 10.14
