If you wish to beta test Catalina you can now download the public beta which as of today is the same as the dev beta 2.
Make sure you have a valid backup either with Time Machine or CCC/SD clone. The beta will take around 30-45 minutes to install and the system will reboot 3X. The download is approx 6.5 GB.
So far it looks pretty good and just as Apple has promised, it will not run a 32 bit app. However, it leaves the 32 bit app in place as dormant.
And in case you're wondering.... I installed it on a Samsung T5 USB-C external SSD.
