Advisory: Next major version of Dorico will require macOS 10.15 Catalina

The system requirements for Dorico 4 can be found here:

The minimum version of macOS that Dorico 4 will run on is currently 10.14 Mojave.

The next major version of Dorico, to be released later this year, will require 10.15 Catalina. This is due to a change in the requirements of the latest version of the Qt application framework on which Dorico relies.

Here is a support document from Apple that lists the models of Mac that are compatible with Catalina:

We’re sorry for any inconvenience this may cause, and want to provide as much notice as possible of this forthcoming change in Dorico’s system requirements on macOS.
