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.

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...
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.

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.

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.
