Apple Releases Revised macOS Catalina Supplemental Update

Apple today released a new supplemental update for macOS Catalina, nearly one week after releasing the first supplemental update and two weeks after the launch of ‌macOS Catalina‌.

The update can be downloaded through the Software Update section of the System Preferences app, but it may be limited to those who didn't download the first supplemental update as it appears to be a minor incremental change that offers the same release notes as the first version.

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
Apple is also working on a ‌macOS Catalina‌ 10.15.1 update, which is available to developers at the current time.

i dont really understand all the griping about updates this season between iOS and catalina. they're not the most solid of releases, but i'd prefer apple to be on more frequent updating schedules.


Your interpretation: Apple is fixing bugs rapidly
Other people's interpretation: Apple has an unacceptable number of bugs that need rapid fixes

they tend to just release the occasional major .x update, but otherwise nothing important happens except for once a year. so especially in the case of iOS, the software gets incredibly stale with the lack of progress, which mostly only takes place with jailbreak tweaks.

Personally, I’d prefer they release fewer, rock-solid releases.

I actually don't get this at all. I've used macs for years and never found them "stale". Usually when UI changes come around I adjust just fine to them...but I don't crave them by any means. They don't change the work I do on my computer vastly, or how I feel about it...

I much rather Apple focus on stability and security than aesthetics, but on the whole I don't feel like I'm yearning for new shiny features every year.


i would be very happy with IOS releasing one year, then macOS releasing the following year, not sure we need yearly releases...

So do I have this correct, this is a supplemental update to the supplemental update?

Or is this a supplemental update to the supplemental update to the the supplemental update?

Something is rotten at the core of Apple if releases are so bad that Apple has to push put immediate updates immediately after a previous emergency update.

That may be your opinion, which is of course valid, but keep in mind many think otherwise as well. There is a reason they are one of the most valuable companies in the world.

I don't care what others think. I don't subscribe to this concept that everyone has an opinion. That's a lie wrong people tell themselves.

There is reason they became the most valuable company in the world, and none of what they are doing right now in the software space resembles that.
