Apple today seeded the second beta of an upcoming macOS Catalina 10.15.6 update to developers for testing purposes, one week after seeding the first beta and two weeks 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 beta, but we'll update this article should anything new be found in the second beta.

Yep still no luck. I'm still running macOS 10.15.5 (19F101) according to system report. Dunno what the deal is.

That’s the build number for 10.15.5 supplemental update. I’m having the same issue where installing the supplemental update has stopped my ability to download the .6 betas.

This has been noticed on the Apple Developer forums as well. The supplemental update blocks it for some reason. The only solution offered is to restore back before the update.

That’s what I figured so I’ll just wait for the release of .6. Probably come around the same time as the first developer release of 10.16. :)

This may be the first Mac OS I completely skip.

Thanks for sharing this. It is a relevant warning for the other users still on much more stable OS Versions like 10.14.6.

Upgraded my 2014 iMac to 10.15.5 from 10.14.6 on 1st of June. Looked quite promising first, snappy and some really nice innovations, none of the problems many other people had seemed to appear. It even fixed some annoyances and small bugs still present in the last Mojave build.
Then, after a few days, Apple Mail began to behave quite weird. Mails were suddenly missing on iCloud Sync at random, leaving many mails which were in iCloud IMAP Folders beforehand now only locally in Apple Mail on Mac, not on the other devices or on iCloud Browser access. Furthermore, Time Machine was suddenly not anymore able to recover anything from Apple Mail.
Contacted Apple Support, 1st and 2nd Level tried some things, but in the end they were clueless. Currrently the item is on escalation for 3rd Level, hope for a callback on Friday...and they are not sure if they can help me. Local Export of Email Folders also does not seem to work properly, mails are left out here.

So no bail-out option via Rollback to Mojave, data loss is a realistic threat and it is unsure if Apple Support can do anything about it.

My advice is simple:
Although there are many people who have zero complaints about Catalina, there are still way to many still having such and other problems. 10.15.5 is definitely not a stable build (...and the users experiencing it as stable do not make it stable for the others who don't), and it is not very likely the final version of Catalina will be stable enough for many users.

So if you have the opportunity to skip / avoid Catalina, just do it.

Instead of restoring to a previous version, you can simply update the SystemVersion.plist file that is stored in /System/Library/CoreServices. There are instructions on this site.
 
So serious, non-snarky question:

Is this the version which is safe for professional workflows? Or is Catalina just going to be a hard pass all together? We’re weeks away from WWDC….
 
10.15.6 Public Beta 2 just showed up on my Public Beta Program machine (a 2013 iMac 27"). Previously, Public Beta 1 didn't show up, because it seems I had the 10.15.5 supplemental update on there. But today's new one is installing now.

No. The only workaround is to delete all photos from an album before deleting the album. Deleting the album with the photos still in it obviously removes the photos from that album but doesn't properly clear the album reference in the metadata, so it never shows in that smart album.
