Apple Seeds Build 12D76 of OS X Beta 10.8.3 to Developers

Tuesday March 5, 2013 3:52 PM PST by Jordan Golson
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.


Build 12D76 comes less than a week after build 12D74 and features no listed changes. Registered developers can download the update on Appleā€™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.

The devs at Apple are watching this thread and giggling.

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.

This damn thing better be rock solid after 13 (and counting) tries.

You have to wonder if Apple is preparing 10.8.3 to be last major update to Mountain Lion.

It's time to introduce 10.9.

Installed 1 hour ago and as far as i can see:

- Scrolling in apps like Safari is now very smooth on rMBP (This hasn't been so in past 10.8.3 Beta Builds) :)
- Boot and Shutdown times are blazingly fast :)
- Wifi seems stable :)

I think this (12D76) is the best Beta Build (Maybe it's compiled without debugging -> GM?).

I don't know what these ******s Apple engineers are doing. It's been close to 9 months for ML now, and they can't seem to iron out any issues. I've rMBP and I've been having system hangs, Safari crashing, graphics glitches and I've spoken to Apple Technical Support on multiple occasions, reinstalled ML and nothing helps. If they take six months to fix the bugs, then how could they claim to release a new OS every year. This wasn't the Apple experience before. I'm not even sure that these ******s Apple engineers and Craig wouldn't introduce 10 new bugs in 10.8.3. It's no longer a pleasing experience using OS X anymore. Apple has become new Microsoft and doesn't want to listen and care about customers.

This is 100% correct. I guess the people that are upset reboot their macs dozens of times per day... So waiting must be infuriating? Otherwise I can't think of any reason why shutdown times are relevant.

Because, I don't want to hang around and see if it did...

For example
1. I don't want to hang around to see if "Mail cancelled the shutdown"
2. Or have to wonder whether Time Machine is in a state where it won't ever let the system shutdown (where ever is defined as finding out the next morning its still stuck on the white screen of half-life) and so have to pull the power cord.
3. Etc.

Nor, per earlier in thread do I want to go through stopping all processes, dismounting all the disks,... isn't that what Shutdown itself is supposed to do?
