Apple today seeded build 12D76 of OS X Mountain Lion to developers, marking the twelfth beta iteration of the newest version of Mountain Lion. 10.8.3 was first seeded to developers in November of 2012.

10.8.3

Build 12D76 comes less than a week after build 12D74 and features no listed changes. Registered developers can download the update on Apple’s Developer Page.

Update: We've heard that Apple has seeded this version of OS X 10.8.3 to employees, suggesting that it is the final version of the software and is likely to be released to the public in the very near future.

This post originally referred to Build 12D76 as the thirteenth developer seed of OS X 10.8.3 when it was actually the twelfth seed.

Leaving aside the pathological desire to update any and all software constantly, I consider thoroughly tested software fundamentally better.

So if Apple really is hammering 10.8.3 this hard to make sure it's clean, I consider that a good thing.

(One could of course argue that they should just let it loose and fix the remaining issues in 10.8.4, but are there any bugs that 10.8.3 is fixing that are so egregious that it needs to come out NOW, thorough testing be damned?)

Does this hold the record for longest run between point iterations of a current-version OSX, though? It's certainly the most betas with no known issues I can remember seeing.
