mavericks.pngApple today seeded build 13D61 of OS X 10.9.3 to developers, just over a week after releasing the ninth OS X beta, build 13D55, and nearly two months after the first 10.9.3 beta. This seed is accompanied by Safari 7.0.4.

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.

OS X 10.9.3 is likely nearing completion, as AppleCare employees were today seeded 10.9.3 build 13D62, one build later than what developers are receiving. A public launch could come as soon as this week.

Weird :s

YES! That is the weirdest thing! Why did I enroll to this program when it doesn't give me the newest beta?

It won't always give you the same betas as developers, and even when it does, you won't necessarily get it at the same time.

Even developers don't get all the betas. They did not get builds 13D19, 13D57, 13D59 and 13D62. (Although there is some evidence that this last one might become the public release - but if developer bug reports necessitate it going to a higher one than this, it won't be).

The ones you get depend on which program you are in and which seed configuration utility you install.

Developers have a different seed configuration utility to the one given to public beta testers.

Why do I need to quote myself?

Memory management seems to have a 10-15% improvement. Utilizing a few programs, I test performance levels after each update. There is a noticeable difference running the same app's on a day-to-day basis on my Mac Pro6,1 8-Core w/ 16GB RAM. Roughly 45-55% of my RAM is used on a general basis, compared to ~30-40% now.
