From the release notes:

Screen recordings taken with Developer Preview 3 are not compatible with earlier releases of OS X

I'm not sure if that's a 'bug' or a 'change', but can anyone with DP3 and ffmpeg/mediainfo/etc check the codec details to see why that is?

AFAIK, Quicktime screen recordings were just Main Profile AVC in a .mov container, both of which are as vanilla as they come. It's weird if that somehow changes, so I'm kinda hoping Apple's testing out HEVC/H.265...

still h264.
 
Is it me or is anyone else's graphics brighter and crisper?

Running it on a current gan Mac Pro5,1 a/ ATI 5780 and 2x 27" Cinema Displays.
 
Is it just me or ....

In finder, in the list view mode, when you resize the filename column and then change folders and then go back to the previous folder, the column has gone back to the default size?

It is you who is getting brighter. But aren't you just fishing... for a compliment?

I can't keep up.

Ok, ok,

It is actually you who has gone back to the default size?
Hmm that doesn't really work.

When in Finder, while viewing your files in list mode. Go into a folder like Documents, resize the name column so that you can see your file names in full. Then go to another folder, like Downloads and then back to Documents. The name column is back to the default size, not the resized size.
 
Swiping between Safari pages is finally working well. I'd love Finder to have this added, I got BetterTouchTool 2-finger Finder swiping in 10.8, broken in 10.9.

hmmm

kinda hoping all the audio people like ableton and the rest have their **** together. I can't afford to be down waiting for updates and I really like the idea of mavericks. Except the whole inability to use multiple monitors as one giant screen. Unless they fixed that already.
 
The tabs in Finder are so badly needed. When I'm dealing with a bunch of windows in Finder, it becomes a mess. I can't believe neither Mac OS X nor Windows has had it in the past.

I can't believe MS went the other direction with Metro/Win8 with having everything new taking up the entire screen...

True,

and being able to use Air screen and 24" simultaneously.

Finally.

I can keep iTunes full screen and use the other for browsing and whatever
 
What I thought was interesting from the release notes:

http://9to5mac.com/2013/07/08/apple-seeds-third-os-x-mavericks-developer-preview/

The QuickTime Player progress bar may be nonfunctional when opening media that requires conversion prior to playback.

It appears that you'll be able to use QuickTime plugins that'll enable you to open up a media format and transcode it across to h264/aac in Quicktime on Mavericks. Does that mean that we'll see Apple Compressor updated to 64bit version as backwards compatibility will mean using the new QTkit media moderniser API call rather than crippling the whole application to 32bit for the sake of backwards compatibility? I hope so because it would be a great day at least for me :)
 
Not asking anyone to betray your developer agreement, but how are you developers liking Mavericks so far?

I liked it the minute I saw Craig Federighi show off airplay mirroring in the keynote video even before I got DP1. So I'm not betraying the NDA by saying that.
