Currently, if you want to use Adobe applications in a macOS environment, you will need the latest version and three previous versions of the OS.
So currently you need versions 13, 12, 11 and 10.15.
However, Apple's support up to 10.15 is also over.
The latest versions of Adobe applications are not available for 10.15.
Currently Adobe offers only two versions, 2023 and 2022, and no lower versions.
In any case, you will need to review your environment.
