I installed Catalina 10.15.2 Beta 2 yesterday. As far as I am concerned all is well. My main Apps work just fine in this Beta update and it is still very responsive. The only information I have discovered about the update is there are bug fixes. I am sure there are bug fixes, that is what beta’s are for, but as far as I can tell there are no new features. If you have waited to install macOS Catalina, maybe the 10.15.2 update may be a good time to do so, just have to wait and see about that.
