I am generally lagging behind in checking support for Catalina for
Isabelle and add-on tools. In the past couple of years our basis for
macOS test hardware has dwindled. At home I merely have a somewhat
pathetic Mac Mini to test it, but I first need to install the new OS
version in the first place.

Concerning CSDP there is a particular problem for macOS: the official
project downloads from https://github.com/coin-or/Csdp are only for
Linux and Windows. The macOS executable that we ship with csdp-6.x is an
older version.

Before that we were using CSDP as "software as a service" over the Net,
but that was very slow and unstable.
