What’s New in macOS Catalina 10.15 GM Seed #1 Beta 11 (19A582a)

UPDATE: 10/9/19 – macOS 10.15.0 is LIVE, What’s New? – mrmacintosh.com/macos-catalina-10-15-0-19a583

Today Apple released macOS Catalina 10.15 GM Seed #1 Beta 11 (19A582a)

Catalina 10.15 GM Seed #1 is here! GM stands for Gold Master, this term is from way back when CD and DVD media was still a thing. The GM build was the final production version of the OS burned to CD or DVD. Now that Catalina GM Build is live, we should be very close to the public release of 10.15.

This article is meant to save you time going through the notes to find what is new and what is still leftover from the last beta. I went through both Beta 10 and the new Catalina 10.15 GM Seed #1 (19A582a) release notes to find all the changes. When Apple releases the next Beta patch notes, the previous patch notes are overwritten and taken down.

10.15 GM Seed #1 or Beta 11 ?

NOTE: I am calling this GM Seed #1 because it’s my bet that we will see a GM Seed #2. The evidence is that Apple is still calling this release.

Install macOS Catalina Beta.app

I don’t know for sure though. Apple could just release the current build and change the name!!!

I for one really hope this is the case, as we still have some things that need to be addressed before launch.

Summary of GM Seed #1 Patch Notes

• 1 New Features
• 1 New Resolved issues
• 0 New Known Issues

Report your bugs NOW!

This may be the final beta left to test. The public Release of Catalina is only a week or two away! You will want to get any bugs that you find into Apple now. If you get them in now, they could be fixed in the current beta cycle instead of waiting until after Octobers’s release date. If you wait it could be months before the fix is put into a dot release combo update.
