Apple Seeds OS X Mavericks 10.9.3 Build 13D43 to Developers

mavericks.pngApple today seeded build 13D43 of OS X 10.9.3 to developers, just under a week after releasing the sixth OS X beta, build 13D38, and a little over a month after the first 10.9.3 beta.

The beta is available 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 Graphics Drivers, Audio, Mail, Contacts and Calendar sync over USB in iTunes, and Safari. As was discovered with the first beta, 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 wish apple would release a lot tighter and more precise change log's. For nearly 1 year they have claimed to, for instance, be working on graphic drivers, yet there has been little to no change in the base branch of the drivers, and barely any change in version numbers either. Performance wise absolutely 0 has changed, and OSX is still under performing like no tomorrow to the point where I am running windows fulltime on my macbook pro (love the macbook as machine) but OSX is simply just not worth it from a production point. Since I can get the same and more on Windows, and everything runs at least 40-50% faster. it's a no-brain'er. Anyway, IF they gave a bit more specific info, maybe at least we could see the direction they are going, test it along the way and give more valid feedback. But in general, they badly need to update the graphic drivers A LOT faster if they want to be taken serious.

(btw. I work in the 3D, video and commercial industry).

Apple just doesn't understand software QA. Nor do they care. It would be kind of comical if it wasn't so sad.


This !

I just don't understand why Apple is so bad with software quality in general. I mean they're able to create some of the systems with the highest user experience available, but in general terms of general software quality they're really awful.

Bugs don't get fixed for ages, features that work on one platform (i.e. Exchange integration on iOS) don't work on another platform (OSX) and nobody knows anything about when, how and if things will get fixed.

I mean c'mon, we can't use our Macs in a corporate environment without SMB, and all other OS-platforms are able to deliver this feature, why is it so difficult for a company that's sitting on a huge stack of money to fix this ?

Microsoft is so much better in terms of platform reliability and enterprise support.

Don't know if I agree they're better in terms of platform reliability –*I work full time with both OS X and Windows in an enterprise environment and there are more issues with the Windows 7 based computers with their Windows updates that takes forever or simply get stuck. The Maces aren't perfect but generally there are less issues with the OS itself I think (SMB support excluded perhaps, but it's okay now with OS X 10.9.2 I think although improvements are welcome).

I think Macs work pretty well in an enterprise environment these days. The little things we have that require Windows (time reporting system wants Internet Explorer 8 or 9 as the latest browser to work) we use Terminal Server.

I've done a lot of benchmarks and came to a conclusion that it's badly written application than bad drivers. Take a look fo example at GpuTest from geeks 3d:
http://www.geeks3d.com/20140304/gputest-0-7-0-opengl-benchmark-win-linux-osx-new-fp64-opengl-4-test-and-online-gpu-database/

I'm getting preety sam results in OS X and in Windows just with 1-2% difference.


That's interesting. Because most games and most benchmark tests I've seen Windows is always considerably faster.

Here for example:

http://netkas.org/?p=1292
http://netkas.org/?p=1287

So, is GpuTest the only software that is ”well coded” because the frame rate results in OS X are similar to Windows? I doubt it. Can it perhaps be that GpuTest is ”bad” on all platforms?

Apple hasn't used Samba for some time now. They wrote their own version of SMB support, and that's why we're having issues.


This is the first reference I have found to SMB. Has anybody tested this build (or any Mavericks) on a local area network (LAN), and specifically in a mixed Mac and Windows network.

SMB is broken in Mavericks. Windows machines, or Windows 7 VM's (Fusion), loose the ability to communicate with the Macs on the network. Additionally, when Macs are forced to communicate only over SMB, they don't work either. This is an extremely serious and critical problem. Therefore, why is it not even mentioned in the Mavericks notes accompanying the beta release?

I've never heard of this, and I have supported several Macs running Mavericks with a mini display port with HDMI output.

Seriously thou, nobody cares if YOU don't have a problem, there's still plenty of us who do (https://discussions.apple.com/thread/5939590?tstart=0)

this is why I think Microsoft will win in the long run if they manage to offer quality materials w/1st party hardware - Apple just doesn't understand software QA. Nor do they care. It would be kind of comical if it wasn't so sad.

I'm running Windows 8.1 on my Macbook Air and I really enjoy it. I might get a Mac mini for dev work, but I'm strongly considering whatever version of the Surface Pro is out in a year or two during my next hardware refresh. 10.6' is small, but 90% of the time I'm at a desk with an external monitor.

To me, it is just as interesting to hear from people who don't have a problem as it is from people who do. That lets us make an assessment of whether it is a universal problem or has a more limited scope. I'm in the "I don't have that problem" camp, at least on this current build, nor does my wife, who is on the current production release. Her MBP is ca 2009, my two are ca 2008, 2013. So while that may not be relevant to you it does let people know who read the discussion that it's not entirely hopeless ;)
