The new ‌‌macOS Catalina‌‌ beta can be downloaded using the Software Update mechanism in System Preferences after installing the proper software from the Developer Center.

We don't know what improvements the fifth update to ‌‌macOS Catalina‌‌ will bring, but it likely includes performance improvements, security updates, and fixes for bugs that weren't able to be addressed in the macOS Catalina 10.15.4 update.

There won't be any tweaks to the design or the display, but later this...

I have lost all faith in Catalina - and if the next release (10.16) is no better, that will be my days of Apple products well and truly over.

I don't understand what the heck you guys are all complaining about...

My Mac Pro is from 2013, my wifes MacBook Pro is from 2014, my daughters MacBook is from 2016, and our entertainment center Mac Mini is from 2018, and they ALL run 10.15.4, and they are ALL running perfectly. No issues whatsoever. I use almost all the Adobe CS applications, in addition to O365, Parallels (for gaming) and the usual apps and utilities. I didn't even clean install, but have only upgraded the last 3 years. My wife is using O365 and a range of educational applications, and have no issues. We both leave our Macs running for days at a time.

What I trying to say is; perhaps it is not the OS, but rather your particular installations?

I hope that the SMB bugs finally will be solved.

It looks like Catalina is going to be the first major OS-X/MacOS release I will skip completely.
