Two new features have been shown in the "what's new in Cocoa" WWCD session and should be visible in the beta (or in the future):
- A new "Show all panes" view à la Safari, for all documents based apps that gained the ability to turn windows into panes in Sierra. It should be accessible in the "Window" or "View" menu
- A new "Add People" option in the file/share menu that basically allows live file sharing à la iWorks for all document-based apps that adopted auto-save (introduced in Lion). This one is big and it's strange that it has not been shown during the keynote.
 
Yes, but not iTunes (at least so far) and iTunes is the only application I know that transfer music to iPhone...

You can AirDrop a .flac file to an iPhone and open it in the Files app. You can also send it through Messages to your iPhone. You can also add it as an attachment to a Note in the Notes app and sync it via iCloud. There are a billion ways to get a file onto the iPhone and let iPhone's built-in QuickLook framework preview it.

I think Apple will announce a new version of iTunes during its September keynote. They did that in the past, and it makes sense. This years' operative system had too sensitive changes and they need to concentrate efforts on that.
 
Does that include MacBook Pro models with dual GPUs? Specifically, the late 2013 15" rMBP? I remember reading that Netkas found that Metal wasn't supported in MacBook Pros with both the integrated and dedicated chips.

Metal 2 being 10x of Metal 1 is, of course, a huge oversimplification. Metal 2 supports argument buffers, which allows significant resource optimization when rendering multiple objects with shared shaders/textures. The catch is this means the optimization heavily depends on the number of simultaneous objects: If you are rendering particle effects or forests with tons of trees or crowds with a lot of similar humans, the improvements are large. If you are rendering one complex object, this does not provide much of an advantage at all. Also, a number of the features in Metal 2 are dependant on the graphics card being used. So your rMBP will support Metal 2 in general, but not necessarily all of its features. I think the latest iMacs and rMBPs are the only machines that support all of the features.

Metal 2 as a brand name also includes CoreML, which is really exciting. I envision AI driven applications popping up everywhere next year.

Can anyone try/expand on this?

Is respect to argument buffers, all discrete GPUs and recent intel GPUs support all features (but apparently, mobile GPUs are limited). They mentioned something related to "raster order groups" that is only supported by the upcoming AMD Vega and (curiously) recent AX chips.
Argument buffers will always help because you never draw a single complex object on screen.

Apps that are using the built-in document model and which in Sierra gained the ability to have tabs, now have the ability to show you previews for each tab.

Apps which autosave using the OS function for doing so can now allow love collaboration.
... or how to explain what I said more efficiently and with more appropriate words.

Can anybody tell if this new feature already usable on beta 1? If so screenshot and post it, thanks.

Although slow and sluggish my iMac mid 2011 runs much cooler than on Sierra.
Normally I have iStat Menus showing around 47 degrees celsius on normal usage - not it barely goes beyond 42 degrees.
Very interesting. I kept a close eye on this in the past 4 days.

macOS High Sierra 10.13 "undocumented" features & changes:
Undocumented items only!
Preferable with images to support your 'tidbit'.
Because this is a wiki post, you're encouraged to add any new features to the list!

  • Native FLAC format support in Quicklook and QuickTime
  • Tweaked Disk Utility
  • Option to Lock the Screen from  menu
  • Content Caching built-in
  • Type to Siri (activate in Accessibility settings)
  • Safari: Per website settings (Always use Reader, Content Blockers, Page Zoom, Autoplay media settings)
  • Safari: Click and hold reader icon to set Always use Reader on this site
  • Local Time Machine snapshots always activated with APFS
  • Drag-and-drop changes: a subtle drop shadow is now cast on all dragging items, and when an item leaves its source container (i.e. dragging text leaves the mail compose window) it scales down during the drag.
  • Photos: "Imports" album shows all imported images going back forever chronologically, not just the last import
  • Photos: Hidden items are hidden from automatic albums such as "Places" and "Videos"
  • Photos: GIFs are animated in the library
  • Photos: Animated GIFs show up in a new “Animated" album
  • Physical media keys now control HTML5 players in Safari (tested on Early 2011 MacBook Pro)
  • Export videos in HEVC format in QuickTime
  • Apps that gained the ability to show windows as tabs in Sierra can now show previews for all tabs in the "View/Show all tabs" menu
  • Document-based apps that autosave using the OS function now allow collaboration via the File/Share menu.
  • System Preferences are now saved to iCloud
NOTE: As always this is NOT a thread for bugs, questions or troubleshooting the betas. All posts must present a new feature or function, or new behaviour not mentioned in the keynote. Please screenshot where necessary. Comments on features are welcome, but stay on topic. This is also not a thread for whining about missing features, complaining, in-fighting or personal agendas. Keep this informative and to the topic at hand.

Please use the macOS High Sierra 10.13 Works/Does Not Work Thread thread for discussing any problems with the new OS.

System Preferences are now saved to iCloud:

Did Facetime get any love?
Not at all in the first beta. But they'll add a useless Live Photos feature to FaceTime in the upcoming betas. I wish they add something more useful like PiP support and make it more stable. Since Sierra they moved FaceTime calls to a separate process, avconferenced, which I believe causes slow frame rate on all of my Macs. It was fine on El Capitan and it hasn't changed in the first beta of High Sierra either...

  • Drag-and-drop changes: a subtle drop shadow is now cast on all dragging items, and when an item leaves its source container (i.e. dragging text leaves the mail compose window) it scales down during the drag.

Can someone make a video recording of the new drag and drop, please?

Maybe can I see that in a WWDC video session on Apple site?

I mean, look at my avatar.. Yes, that's me :cool:
