Apple today seeded the third beta of an upcoming macOS Catalina 10.15.6 update to developers for testing purposes, three weeks releasing the second beta and over a month after releasing macOS Catalina 10.15.5 with battery health management features for Macs.


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.

Any news about the persisting Apple Mail Bugs? Apple Support confirmed my iCloud sync issue is an unresolved bug in the current version of Apple Mail in 10.15.5, but so far had no details on an estimated fix date. Currently no workaround possible instead of refraining from using Apple Mail at all...

I think the OP might be referring to SSV.

Very interesting. Looks like it can be disabled, though currently seems to be a bit of a PITA. Of course, disabling SFF also reduces security, although not less than Catalina obviously.

Mojave. The new snow leopard?
I'm on Mojave and my 2014 MBA" with just 4GB RAM still going on without any major problem.
I'm probably getting an ARM MBP some months after the release after the reviews and people's experiences, or just wait for 2nd gen but if something I'm sure about it's I'll be skipping Catalina (as I skipped Lion & Mountain Lion until Mavericks)
