Apple Releases macOS Catalina Supplemental Update With Fixes for Installation, iCloud Login, and Game Center Bugs

Go to the App Store and search for MacOS Catalina, it should show up there
Does this fix the major issue with mail data loss? If not, then Catalina remains too risky for use.
Also have the GM, then opted out of beta. Not showing up for me, either...
Any one got the build number on the supplemental?
Supplemental updates already?! Really?! I've hated this "idea / naming scheme" ever since Apple introduced it to Snow Leopard 10.6.8 Update v1.1. Why they just didn't call it 10.6.9 and leave it at that is beyond me. And now, how many Supplemental Updates have Mojave suffered? Does Update 2 include Update 1? Or do you need both? And here we are, already 10.15.0 has a Supplemental Update.
What a mess.
What a mess.
Seems to fix that really annoying constant colour change with True Tone - that was hurting my eyes.
I have not read on numerous forums nor heard from a few friends who are Apple Store geniuses that Catalina is a stable & solid upgrade. Hence, I will wait until at least 10.15.6 or higher. Yikes 
Does it fix the Mail permanently deleting messages problem?
Looks like it might include a fix for the sudo vulnerability: looks like a new binary and the previous sudoers file was pushed aside/renamed.
Oh and: my download went quickly, no hangups (western US). As other mentions, guessing maybe the servers they are hitting are getting swamped.

Well, they dropped the "X" from the name OS X three years ago and gave us macOS. Maybe next year, we would get iOS 14… and macOS 16, not 10.16. A smaller "supplemental" update like this one released today would make the version 16.0.1. And bigger updates would be 16.1, 16.2, just like on iOS.
I’m really excited to use Catalina but I think I’m going to wait a little while longer. The public beta was okay but with reports of how flakey the general release is, it doesn’t fill me with hope.
They could do us all a favour and instead of supplementing an update for Game Centre, just remove it entirely for the love of God.
zero issues. best update for years.
We are all very impressed.

You need to search for and install Catalina on the App Store.
Software Update doesn't play nice with GMs after you've left the beta program. Same happens with Xcode. Go to the App Store and download the full release installer, which by now also has this fix. That will get you back in sync.
Already releasing a supplemental update is ridiculous. They should never have shipped macOS Bètalina without these fixes. I mean, a bug that lets the installation hang?! That’s a bug you definitely want to get fixed in the last beta before you ship the final product to your customers who RELY on their iMac’s and MacBooks for work.
Get a Mac. It just works*

It seems the update also resolved the issue where the UI smoothness is significantly worse when mirroring the displays instead of extending them. Will need some more testing to be 100% sure.
