No at the moment PT only work up o Mojave . Don't install Catalina i already did it myself and still in public beta . Protools wont even open on it so have to wait . I l've tested catalina beta 2 but beta 3 is out there about a day ago i think . Im gonna test again when have time with beta 3 . I have to say that appart from Protools Catalina feels smoother and snappier than mojave and my benchmark improves a little .
In my case ia for testing purposes so it is still in beta and mojave was just officially suported by Avid
. Btw mojave runs very good with PT so no need to update now .
