Apple Seeds Sixth Beta of macOS High Sierra to Developers [Update: Public Beta Available]

Apple today seeded the sixth beta of an upcoming macOS High Sierra update to developers for testing purposes, one week after seeding the fifth beta and more than two months after introducing the new software at the 2017 Worldwide Developers Conference.

The sixth beta of macOS High Sierra can be downloaded from the Apple Developer Center or over-the-air using the Software Update mechanism in the Mac App Store.

Today's update brings a fix for a bug that caused apps to quit unexpectedly when printing to Canon printers, and it addresses an issue that caused QuickLook to preview things to force a MacBook Pro to switch to a discrete GPU (pertains to models that have both discrete and integrated GPUs).

macOS High Sierra builds on features first introduced in macOS Sierra, focusing on new storage, video, and graphics technology. It brings a new Apple File System (APFS), High Efficiency Video Codec (HEVC), and an updated version of Metal with support for VR and external GPUs.


Several apps are gaining new features in macOS High Sierra. The Photos app features a new sidebar to make it easier to access editing tools and albums, and there are new filters and editing options like Curves and Selective Color. Photos also supports external editing apps like Photoshop and Pixelmator, saving changes made in those apps back to Photos, and it interfaces with new third-party printing services.

Safari is gaining speed enhancements, an option to prevent autoplay videos, and a new feature that cuts down on cross-site data tracking. Siri in macOS High Sierra has expanded music capabilities and a new, more natural voice, and Spotlight supports flight status information. There are also improvements to iCloud, FaceTime, Messages, and Notes.

macOS High Sierra is available for both registered developers and public beta testers and will see a few more weeks of testing ahead of its expected fall public release.

Update: Apple has also made a new version of macOS High Sierra available to public beta testers.

Not quite sure why the Public Beta (which is identical and even is listed as the Developer Beta in the App Store) won't be released until tomorrow afternoon.
Apple likes to collect installation data first before opening up to public beta. Developers tend to be a lot more resourceful if something goes wrong during installation AND they often have multiple devices.

Many that install public beta are equally knowledgeable but more likely install it on their primary device.

Apple doesn't want to support it.

DO NOT INSTALL Beta 6, it will bork your iCloud account. When the update finished, I saw a message that read, "Your iCloud account has been locked for security reasons". WTF, it has been working fine for years.

I tried to "fix" the issue by following Apple's steps and the service would not update my password and now I am locked out. Great!!! My business is dependent on my ability to access my account and data.

Sigh... now I have to call Apple support.
Am I going to be the first to ask why you are running beta software on your production machine?

Perhaps you could download it and then upload it to MediaFire or something?
I know. I was trying to upload to some sites.

Here it is.
