Apple Seeds OS X Mavericks 10.9.2 Build 13C48 to Developers

Apple today seeded build 13C48 of OS X 10.9.2 to developers, marking the fourth beta iteration of 10.9.2. The release comes a week after the third OS X 10.9.2 beta, build 13C44, and a little over a month after the first OS X 10.9.2 beta.

13c48
The update is available to registered developers through the Software Update mechanism in the Mac App Store as well as through the Mac Dev Center.

Apple continues to ask developers to focus on mail, messages, graphics drivers, VoiceOver, VPN, and SMB2. Earlier betas of OS X 10.9.2 began allowing Mac users to block people on iMessage and FaceTime, as can be done in iOS 7, and also introduced FaceTime Audio.

That's the theoretical hardware support. It does not mean that OS X 10.9.0-10.9.2 is the best OS for 4K displays.


The BEST OS for 4K displays... let's throw some subjective squabble out there rather than answering the actual point.

It clearly proves that Apple supports 4K displays (MULTIPLE 4K displays.) Some aren't supported and there will be subjective flaws...etc as usual, but there is support for 4K displays. Saying there isn't is incorrect...

Apple does not support 4K displays @ the moment.

That statement is false.

Has anyone checked whether 10.9.2 exposes any new OpenGL extensions / functionality?

If you download the OpenGL Extensions Viewer (https://itunes.apple.com/app/opengl-extensions-viewer/id444052073?mt=12) and go to the "OpenGL", "Extensions", or "Report" tabs, you can see a list of what your system supports.

For reference, here is what's displayed in Mac OS 10.9.1 on my system:

What is reasonable scaling ? It's a 4K display. If you want lower resolution don't get a 4K display.


Scaling is not reducing resolution.
Scaling is keeping high resolution and just making UI larger (which is perfectly fine and reasonable).

Thanks for your sources. Very convincing. ;)

you're kindof being an ass, but i wanted to see for myself: http://support.apple.com/kb/HT6008?viewlocale=en_US&locale=en_US

Does anyone know whether or not HiDPI support is provided for external 4K monitors?


I doubt that, because Apple does not support 4K displays @ the moment.


Apple are selling a 4K monitor: http://store.apple.com/us/product/HD971LL/A/sharp-32-pn-k321-4k-ultra-hd-led-monitor

You are saying that Apple do not support the monitor they are selling?

Other 4K monitors, such as Dell, also work in 10.8.5 and 10.9.1 but only at native resolution.

Still, OSX does not support any reasonable scaling modes for those 4k displays!

IMHO a major weak point in OS X (compared to Microsoft Windows) is the lack of scaling, period. I don't feel that the doubling it does for Retina Displays counts, although it would certainly be useful for a 4K display.

I'd really like to see them update the OpenGL to 4.4 in the near future, I don't know why they settled with 4.1. However the main thing I'd like to see change is for Apple to remove the compatibility profile because there's a lot of cross-platform apps like Minecraft and Second Life which are using the compatibility profile even though it's ancient. So if they took out then they'd be forced to move to the core profile like Apple intended everyone to do.

I would really encourage anyone who wants to see updated display drivers to submit feedback through Apple's feedback form:

http://www.apple.com/feedback/macbookpro.html

Especially regarding the enabling of MST and the handling of 4k displays.

They do periodically use the data from the complaints here to get a feel for what issues are important to users.

Here is mine:

As documented at the following link and elsewhere on the internet:

http://9to5mac.com/2013/12/23/new-retina-macbook-pros-can-drive-4k-displays-at-60hz-when-running-windows-mac-os-needs-new-drivers/

The current display drivers for the late 2013 MBPr do not support using MST to drive 4k displays at 60Hz.

This a use case that is supported by the hardware itself, but not the drivers. Display hardware that runs 4k is readily available these days, with more models already announced, so this is a significant compatibility issue.

Please address this as soon as possible.
