Anybody tried SWI on Mac OS 10.15 (Catalina)?
I installed version 8.0.3 with home brew on Catalina and it at least starts up and runs the basics! This approach may not always give the newest version, but at the time of writing this I got the newest stable version.
I use SWIVM to install the latest versions without any issues. See https://github.com/fnogatz/swivm
