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

Alongside iOS 13.1.3, Apple today also released a supplemental update for macOS Catalina, addressing several bugs from the initial public release version, including a problem with Setup Assistant hanging during Catalina installation.

The macOS Catalina Supplemental Update includes installation and reliability improvements, and is recommended for all users.


This update:
- Improves installation reliability of macOS Catalina on Macs with low disk space
- Fixes an issue that prevented Setup Assistant from completing during some installations
- Resolves an issue that prevents accepting iCloud Terms and Conditions when multiple iCloud accounts are logged in
- Improves the reliability of saving Game Center data when playing Apple Arcade games offline

Today's supplemental update comes ahead of macOS 10.15.1, which was seeded as an initial developer beta last Friday.

985.4MB update to fix icloud and installation issues. I've been using Catalina and really regret, Mojave was way more stable. Sidecar doesn't work (timeout!), iCloud is buggier than ever and now my computer even awakes randomly (powernap is off!). Worst update in years.

Yeah, I’m still going to wait until early next year to update to Catalina.

Wish they would call it macOS 13.0.1 and dispense with unversioned "supplemental updates".

I recommend Catalina. Seriously. You gotta do your own research though if you still need to use 32-bit apps or if you're a DJ and need to adapt something or something about your workflow with the iTunes library (? I'm not a DJ), other than that I'm finding that the posts here make the problems seem blown way out of proportion. If you read closely there is little substance, a lot of knee jerk reactions to unsubstantiated claims. If you do upgrade, my prediction is one day you'll install 10.15.1 that will fix bugs you never knew existed in 10.15.0. I see the same whining every release, whether it's macOS or iOS. Sure there are bugs. Sure there seems to be more whining this time. It's a new feature release. New feature releases tend to have more visible bugs than 'under the hood' performance/stability releases. Sure some people will be affected. But 99% of people will never actually experience a bug that has any affect on getting work done. I stand by that statistic even though I pulled it out of my ear. Unless you don't care about the new features and are satisfied with Mojave (and still don't feel confident about Catalina), I'd say do the research, then go for it.
seriously, just get real for a moment, Mojave didn’t have near this much complaints after launch.


Apple OFFICIALLY recommends Mac Mini users TO NOT upgrade to Catalina yet. When was the last time Apple said “please, it’s best to avoid our newest OS until we fix it”?

It is awesome that you don’t have any issues, but just because you do not have any issues, do not accuse many people out there that they are lying or over exaggerating things.
