ST Link Server installation fails on macOS Catalina
ST developers need to keep up-to-date with those changes. The cause is that in Catalina Apple introduced r/o system partition, so any old installers that attempt to write there are now incompatible.
/Applications are now a link to r/w partition, but any other system directories are r/o
While st-link server writes client side files into /Applications some things are written to other system directories, so it fails.
