macOS Catalina Developer Golden Master

I just installed the Golden Master of macOS 15 Catalina on an external SSD. It is huge at 5 GB. This is the version of Catalina that will be released in a few days. It runs really well, a very fast operating system. All of my main workflow Apps work in it just fine. Again, you might want to install this version of macOS with caution because the major security changes.
