Latest Catalina Beta



Apple Beta Software Program

Download the latest Catalina Installer using the latest Catalina Patcher version. Some third-party applications do not open or crash on launch This is an issue Apple introduced in 10.15.4, and is not an issue with the patch itself. Apple also released the third developer beta of macOS Catalina 10.15.3 after releasing third beta versions of iOS 13.3.1, iPadOS 13.3.1, watchOS 6.1.2 and tvOS 13.3.1 for developers this week. While the company does not share the content of the update, the new update is expected to focus on performance improvement, security updates and debugging. The other day, we showed developers how to install macOS 10.15 Catalina Developer Beta 1 onto a Parallels Desktop virtual machine.At the same time, we offered a few cautions about doing so — the beta operating system runs slowly on Parallels at this point and there are some other issues.

UPDATE: 10/03/19Catalina 10.15 GM Seed #1 is now live! What’s New ?mrmacintosh.com/whats-new-in-macos-catalina-10-15-gm-seed-1-beta-11-19a582a/

Today Apple released macOS Catalina 10.15 (19A573a) Beta 9 to Developers.

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 8 and the new Catalina 10.15 Beta 9 (19A573a) release notes to find all the changes. Like usual, I also have included the entire patch notes list as an archive. When Apple releases the next Beta patch notes, the previous patch notes are overwritten and taken down.

Summary of Beta 9 Patch Notes

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

Report your bugs NOW!

This may be the final beta left to test. The public Release of Catalina is only a few weeks 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 September’s release date. If you wait it could be months before the fix is put into a dot release combo update.

Latest Catalina Beta 5 Review

Some fixes are not going to be listed. Many issues are from #MacAdmins who have filed FeedBack Requests and Enterprise Support tickets. Most of these issues are resolved but are never publicly noted.

1. New Features in Beta 9

iCloud – Launch daemons and launch agents introduce new user privacy protections. Specifying privacy-sensitive files and folders in a launchd property list might not work as expected and prevent the service from running. Having Program or ProgramArguments pointing to an executable in a privacy sensitive location is currently allowed, but may be restricted in a future release. (49702405)To comply with the new privacy protections, resources for a launchd service must be stored in locations that aren’t privacy sensitive. If necessary, the app can set up resources during its execution rather than using launchd property list keys, making it possible to grant the app access using System Preferences > Security & Privacy > Privacy. The following launchd property list keys are affected: KeepAlive, PathState, QueueDirectories, Sockets, SockPathName, StandardErrorPath, StandardInPath, StandardOutPath, and WatchPaths.
