Apple Seeds Build 12D54 of OS X 10.8.3 to Developers


Apple today seeded build 12D54 of OS X Mountain Lion 10.8.3 to developers, marking the sixth beta iteration of the newest version of Mountain Lion. 10.8.3 was first seeded to developers in November.

Build 12D54 comes just eight days after build 12D50, and like the previous build, contains no known issues or features. Build 12D50 brought only minor changes, and asked developers to focus on testing AirPlay, AirPort, Game Center, Graphics Drivers, and Safari.

9to5Mac notes that the new build contains significant changes to WiFi, but additional changes are unknown. Registered developers can download the update on Apple’s Developer Page.

This post originally referred to Build 12D54 as the seventh developer seed of OS X 10.8.3 when it was actually the sixth seed.

still no reason for "switching" from SL to ML. i have to admit that airdrop is nice, but not so widespread. all the social cr@p can go to hell. i want back proper exposè and spaces.


I'm so tired of reading this. First of all, "all the social cr@p" is completely optional and not at all intrusive. It can be completely turned off. Second of all, SL didn't have "proper" exposè. "proper" exposè ended with Leopard. SL added the scaled exposè which many argued was worse. ML brings back proper, unscaled, exposè.

Still don't like it? Don't use it then. But this completely unconstructive whining has to end.

Still don't like it? Don't read it then, don't even bother to quote. Because this I-hate-SL-buggers-ML-being-latest-and-greatest-wannabe whining has to end. :rolleyes::rolleyes:.

Says the guy who always post in ML related threads to whine about how ML sucks and SL is the best :rolleyes:

Yeah, there's also icloud support, which is a huge reason to switch IMO.

Then don't read it... First of all, though "all the social cr@p" is completely optional, its processes are not, and thus cannot be turned off whether you use it or not. It's a bloatware to say the least. Secondly, Leopard has the "proper" exposè, SL is the refinement of it. It looks a lot cleaner than some random windows thrown at your screen. I just don't understand why would Apple want to reverse it with Lion and Mountain Lion. I guess that's the very sign that Apple is going BACKWARDS hence the lack of innovation after SJ got beaten back to his grave.

Wow, they're really making a lot of fixes in 10.8.3. I can't wait to download it.


12D54 and you say it's a lot of fixes...? In Snow Leopard, I guess they fixed a lot more with 3-digit builds. That's why Mountain Lion is still a piece of ****...

I hope this makes Safari snappier... Ha, you didn't see it coming! :p

You guessed it wrong. I came from the Tiger era where Expose had already been introduced on Panther. Leopard came and went, but because Apple introduced a bunch of new features that bloated it, I skipped and went straight to Snow Leopard. Boy how happy was I when Expose (complete with captions) was refined grid-style. Most importantly, Snow Leopard got rid of support for PowerPC-based Macs, I guess that was what made it lightweight and stable...? Apple did emphasised that Snow Leopard was to be an under-the-hood refinement of Leopard. And yes, I was aware of how people would hate SL Expose that they would hack it to revert to the old-style Leopard Expose...

Lion came, Expose and Spaces (another PITA feature devolution) were unified. I guess I don't need to explain further on Expose as it was a total mess just like Leopard, and groped (yes you read it right - groped!)...! :eek: Mountain Lion came to reverse some of those mistakes, but unfortunately it still retains the mess of Leopard.

Expose aside, Mountain Lion is as much as bloated as Leopard, though it supposed to carry some refinements over Lion, but it does not come close in performance and stability of Snow Leopard. People have been saying, and thus proving for instance, graphical performance is superior in ML than SL. No doubt it's true. But at what cost...? Instabilities...? Graphical choppiness...? Why the iOS fanciness with unnecessary resource-hogging windows animations...? I BOINC my science project every now and then, SL does one WU by 1h 50m, ML does in 1h 49m...? I wouldn't trade 1 minute of performance over such aforementioned problems.

SL starts up with less than 400 process threads, while ML starts with over 600... They stay there whether or not you utilise the iOSified features. Bloated isn't it...? Expose is just one of the many screw ups on L/ML.

Now we're seeing an annual cycle update of OS X, which means more features will be introduced, more resources will be needed, consumer will have to upgrade more often, maybe 2 to 3 years once as opposed to 4 to 5 years during the PowerPC era...?


So... you wouldn't at all mind if I came to every forum thread where the OP discussed how great SL is, or SL in general, and bashed it, complained, and whined?

And which part of my sentence did I equate threads to performance....? :rolleyes:

Well your whole rant implied that the number of threads was a negative thing, and the system was "bloated" because of it. When people say something is bloated, it usually means it is heavier, and slower than it should be.

If you are not worried about performance hit, and if you know that you may "not use" those extra features that create those extra threads (I'm not even sure that's the case here, extra threads can be created even with the same features just threaded in a different way), then what exactly are you on about when you say "bloated"?

Don't look at the number of threads on activity monitor and there, your problem is solved. I wish everyone's issues with OS's could be solved just as easily.
