    Media Composer 2018.12.15 on MacOS Catalina (or newer)

    Hi all-

    We're being asked to run MC 2018.12.15 along with Mimiq (now owned by Hedge) to facilitate bin locking on third-party storage.

    Mimiq only runs on MacOS 10.15 (Catalina) or later, while Avid's compatibility docs claim that 2018.12.15 is only supported up to MacOS 10.14 (Mojave) and doesn't list any later OS versions.

    Is anybody successfully running 2018.12.15 on Cataina or newer? Did Avid just stop testing the older version, or is there a hard and fast reason it can't work?

    As an aside, what's the last version of Media Composer that featured the "old" style user interface?

    Thanks in advance,

    Hey there Ryan

    No it wont work......   

    Media Composer 2018.12.x won’t support macOS Catalina and it will never support it since it would require removing a lot of 32-bit code already in 2018.x and making large changes that could have adverse effects on users who rely on 2018.x. 

    Sorry but it wont work.
