The macOS Catalina 10.15.6 beta can be downloaded from the Software Update mechanism in System Preferences after the proper profile has been installed from the Apple Developer Center.

There's no word yet on what improvements the new update to macOS Catalina brings, but it likely includes performance improvements, security updates, and fixes for bugs that weren't able to be addressed in the previous update. No new features were found in the first two betas, but we'll update this article should anything new be found in the third beta.

Does this fix screen freezing or stuttering at random when using "automatic graphics switching" by any chance? I'm sick of this.
