One week after the previous seed, Apple today released a new build of OS X 10.8.3 to developers. The latest version, which arrives as build 12D78, represents the 13th developer seed since Apple began developer testing last November.

12d78
As with previous builds, Apple is asking developers to focus their testing on AirPlay, AirPort, Game Center, Graphics Drivers, and Safari.

We had previously heard that Apple was seeding the prior 12D76 build to employees, suggesting that a public release might be imminent, but it seems that Apple is continuing to make final tweaks to the operating system update.

You guys are hilariously insufferable.

If Apple rushes out the update then you moan that QC is down and no one tested the software before release. If Apple takes its time prepping an update then you cry that its taking too long, they suck, and only care about iOS.

I mean seriously...

I updated with new calculations (hope I got them right). Anyway if accurate crazy compared to the other top spots which were not anywhere as early as .2 to .3 releases.

Craig Federighi took over OSX at Apple about when 10.8.2 was released.
I am told by people within Apple that he has an engineer's mindset and has been very disappointed with the stream of minor bugs and irritations that built up within Lion and Mountain Lion.

This long delay with 10.8.3 may (let's hope so) confirm this.
It would be nice to believe that, every week, he tries the latest 10.8.3 then comes into the engineering meeting screaming "Does it fix the power management bugs? NO! Does it fix the locationd crashing bugs? NO! Does it fix the Finder caching and displaying out of date information bugs? NO! So go and fscking fix them. Because no way are we EVER shipping again a piece of software as buggy as we have over the past eighteen months --- not as long as I am in charge!"

Some people really need to get a life. Apple can do betas as often as they want to. They will release it when it's ready.
