Apple today seeded build 13D17 of OS X 10.9.3 to developers, one week after releasing the first OS X 10.9.3 beta, build 13D12. The beta is available through the Software Update mechanism in the Mac App Store as well as through the Mac Dev Center.

Apple is currently asking developers to focus on Graphics Drivers and Audio. As was discovered last week, 10.9.3 adds new support for 4K displays, offering "Retina" resolutions that improve readability along with support for 60Hz output from the Retina MacBook Pro.

I see the same text in 9toMac it is 60 Hz not 60 GHz, please correct the info. ;)
 
60Ghz huh? That's pretty good. ;)

Sorry, uncooperative brain today. I was writing an email about a processor just before this and didn't even notice the Ghz. Fixed :)
 
You might take note that MacRumors actually has useful information in it.

At the time I posted there was nothing else here about it.

So information I provided was useful.

I didn't know how long it would take for a news story to go up here about it.
 
I have 3x displays. One of them is an HP Compaq LA2405wg @ 1920 x 1200.

With 13D12, it offered me the option of Scaled 2560 x 1440 (or similar - it might have been 2560 x 1200 or 2560 x 1600)). I selected it, and it made everything really tiny on that display. It seemed to work just fine though.

With 13D17, that option is gone. It now offers 1920 x 1200, 1600 x 1000, and 1280 x 800.

My Apple Thunderbolt Display offers 2560 x 1440, 2048 x 1152, 1600 x 900.

My HP Compaq LA1905wg (in portrait mode) offers 900 x 1440 or 960 x 1280.

They posted less than fifteen minutes after you and had actual information from the developer site.
 
Typical current Apple. They can't even provide developers with a working seed link via the developer portal w/o ********** it up.

Good god.
 
They don't put direct links for betas on the portal anymore. They are in apple's developer forums now.

Alternatively you can get the seed configuration utility from the portal, install it, and then get the seed from the mac app store.
 
I have a 4K Dell UP3214Q and I've just plugged it into my 2012 Retina MacBook Pro until my nMP arrives next month.

With 10.9.3, can I do display scaling?
I'm currently running 4k@30hz on 10.9.2, and I'm wondering if 10.9.3 would allow me to do display scaling until my nMP arrives, or is display scaling limited to Thunderbolt 2 devices?
 
I really love the look of the OS X Mavericks icon.

Particularly looking forward to this point release, if it means graphic drivers for some optimized gaming performance :D

Did this fix the audio bug introduced in the first beta build 13D12?

I can't really tell because it didn't affect my computer in the first place. But some developers found that audio disappeared and had to restart to get it back.

I would't want apple to rush this out to the public if the audio problem is still there.
 
BORING...! GUI is still choppy...! :mad:

Ever wonder why Apple never get things done the way it should have been pre-Lion...? :confused:


NEXT...!!!
