Apple Seeds Sixth Beta of OS X Mavericks 10.9.2 to Developers

mavericks.pngApple today seeded build 13C59 of OS X 10.9.2 to developers, marking the sixth beta iteration of 10.9.2.

The release comes roughly a week after the fifth OS X 10.9.2 beta, build 13C53, and nearly two months after the first OS X 10.9.2 beta.

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.

Super Mario Bros 2 being included is probably the biggest surprise.

It happens on SSD's too, but besides that, why should running the OS off of an SSD be a requirement to get a lag-free OS? That's just Apple not knowing how to optimize an OS and relying on better hardware to cover sloppy coding.


I completely agree with you here, but about all MBPs have been suffering from lag issues ever since 10.7 at least and Apple never fixed it.

Although Mac OS X improved a lot between 10.0 and 10.6, dropped a lot in 10.7 and again improved from 10.7 to 10.9 it's speed is nowhere compared to Mac OS 9.

I am very heartened to see SMB2 on the list of things they're focusing testing on. Word on the street is that 10.9.2 will finally fix the serious SMBD problems that have been causing me headaches to no end with my Windows users, which I'm desperately hoping is true.

I don't want it to ship until it's ready, but that can't happen soon enough.

This might answer your question.

1. Bertrand Serlet
S.V.P. OS X Engineering
10.4-10.6

2. Craig Federighi
S.V.P. OS X Engineering
10.7-10.9

I applaud 10.9 for [finally] addressing SMB2, multiple displays, OpenGL 4.0+, memory management, and other power user related issues developers have filed since 10.7, it is still a far cry from the OS X installments under Bertrand Serlet. Couple this with iOS engineering focus and Apple's increasing insistence on moving engineers off OS X to iOS development instead of actually hiring more capable engineers, and you might see a pattern.

I just want them to fix Mail for once and for all.

I'll give them an easy hint: copy the code to handle the back end from iOS. It all works perfectly over there.

Yes, I'm aware it's a beta. I'm a developer and have used OS X and iOS betas for year. Just think it's a particular strange bug his late in the process.

Is anyone else experiencing this?

There looks to be a new app rating system by the name of the app. If you click it, it tells you about each rating and the age appropriate for that app.

Airmail app solves this problem ;)


But that's what that postage stamp thingy sitting in my Dock is for. No need to pay for something that's not working and is part of the core OS. :p

If Apple can make a super duper mail client for the iPad why can't they get the OS X Mail App working without the need to buy an App?

True, my Macbook has been suffering from lag issues in various situations.

In Mavericks, just after a couple of days the Mac is on (either being used or sleeping), the changing spaces and mission control animations get jerky to the point where I have to restart the computer. I'm using MBP mid-2010 13".


I have a MacBook Pro early 2011 - it has been awful with lag in 10.9 betas. The GM was okay, but still lots of lag. The newest beta is working much better for me (not sure if its the beta or the 16g of RAM I just installed - had 4).
