Apple today seeded the fourth beta of an upcoming macOS High Sierra update to developers for testing purposes, two weeks after seeding the third beta and more than a month after introducing the new software at the 2017 Worldwide Developers Conference.

The fourth 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.

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


Some apps are gaining new features in macOS High Sierra. The Photos app is being updated with a new sidebar that's designed 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, and it interfaces with new third-party printing services.

Safari is gaining speed enhancements, an option to end autoplay video, and a new feature that puts a stop to 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 several updates ahead of its expected fall public release.

do we now have support for APFS on the 2010 Mac Pro?

Should work on every Mac that supports High Sierra. I couldn't select it while installation on my Mid-2011 iMac. But I think that's only why it's optimized for SSDs and my iMac doesn't have any. It is in Disk Utility and I think I can convert my drive from the Recovery Partition. Did not try it yet. At least in the running OS it is greyed out.
 
Has anyone tested if Safari can playback 4k in YouTube? I was stunned to learn in current Sierra it cannot. I have to use Chrome.

APFS is/was not (yet) supported on the 2010 Mac Pro. the release notes specifically mentioned this.
I would like to know if Apple has implemented this feature in DP4...

No, still no support for APFS in the 2010/2012 Mac Pro, according to the release notes.

Hmm, starting to get rather concerned about this. You'd think that by DP4 it would be implemented if they're going to do it.

Sadly, Safari only supports up to 1440p in Youtube right now, not sure why. Chrome supports full 4K youtube though.
 
Looking forward to a new Public Beta Release -306F has so many annoying bugs.
issues include:
Mail - search has been disabled.
Safari: Phantom boxes appearing when completing forms. They measure about 1.5" x 1.5" or sometimes small rectangular boxes. These are static and will appear on all tabbed pages. (full screen mode)
Preview: cannot save or print markup pages. Saving as new PDF only saves as original with no markups.
Command Space: will not bring up applications.
So many other issues not worth mentioning.
Love being a PB tester because I know that our reporting makes a better end product for the consumer which translates to higher stock prices. But please apple, send out a new PB soon so that I can work more efficiently


System:
Late 2017 27" iMac i7
fusion and 32GB ram

Still no support for 3TB Fusion Drives, install at your peril!

Technically the Developer notes mention 3TB fusion drives AND Bootcamp may be unsurpported.

Unless I’m reading that wrong it’s not saying 3TB fusion drives would have issues. Just 3TB fusion drives using bootcamp could have issues.
 
"Stops data tracking"....yep....for about a week until the sharks figure out how to get around it. Then...back and forth forever.

Might be codec related as some older 4k (like from 2013-14) does work in Safari, but most new ones I tried just now are 1440 max.
