Apple Seeds Build 12D54 of OS X 10.8.3 to Developers

by

build12d54
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 ****...
