Apple mysteriously reissues last week’s macOS Catalina‌‌ Supplemental Update

Catalina looks pretty good, but should you install the public beta already?

Apple today introduced a macOS Catalina‌ Supplemental Update that’s apparently only very slightly different from one made available last week. It’s not clear what is different about this version.

macOS Catalina‌‌ Supplemental Update: Take 2

macOS Catalina 11.15 launched in October, bringing the end of iTunes, Sidecar, and loads of new features.  Last Tuesday, Apple fixed some of its bugs in an update that, according to the company “includes installation and reliability improvements.”

A “new” Supplemental Update came out today, but its description is identical to the one introduced a week ago.

The changelog for both says:

“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.”

It’s not clear whether those who installed last week’s update should also put this new one on their Mac, or even if that’s an option for everyone.

Installing the macOS Catalina‌ Supplemental Update is done through the System Preferences app by going to Software Update.

Apple is already hard at work on the next major update of Catalina. The second macOS 11.15.1 beta is out, adding some features to the Photos app, as well as making a few other minor enhancements.
