At the risk of invoking "Marathon Man", now that I've successfully upgraded to Indigo 7.4 on Mojave, I'd like to upgrade MacOS to Catalina. Is it safe to give it a shot, at least with regard to Indigo?
I haven't seen many comments about experience with Indigo 7.4, post Catalina. A lot of BS about wanting older versions of Indigo to work with Catalina, but not much about how it has been going if I were to upgrade to Catalina with the 64-bit Indigo Server.
