Apple today seeded build 12D50 of OS X 10.8.3 Mountain Lion to developers, the fifth beta release reports 9to5Mac. The first 10.8.3 beta was seeded back in November, and the third and fourth releases were released in December.

Though the update comes with no known issues or new features, as before Apple has asked developers to focus on AirPlay, AirPort, Game Center, Graphics Drivers, and Safari in their testing. Registered developers can download it via the Apple Developer Page.

Here's what needs to be fixed:

1. Apple's laziness to launch an OS with so many glitches in their OWN unique hardware.

2. Stop adding BS social features and focus on quality.

3. If Apple wants to add new features, then start copying Windows 8 GREAT file copying and management. That is what desktop OSes do, anyway. This is not an iPad.

I agree with the slow shutdown times. I had a 2007 iMac with Mountain Lion. I put Snow Leopard back on it to sell it.

Mountain Lion: 30-35 seconds to shutdown
Snow Leopard: 5 seconds to shutdown

Even with my newer 2011 iMac, shutdown times are around 30 seconds. It doesn't bother me. I just find it strange. :D

Well see now. Macs aren't used to being shut down or rebooted. That's a Windows thing.

:D

That's what snow leopard was for. Even still lion and mountain lion didn't really get any compelling features. Just social crap and dumbing down of a lot of stuff to make it more like ios (Quicktime being a prime example - they remove most of its preferences for no reason at all)
Quicktime 7 has a 32-bit API that is ancient. 64-bit is the future but taking Quicktime 7 to that future isn't a straightforward process (http://arstechnica.com/apple/2009/08/mac-os-x-10-6/6/) and will take time. And if you owned Quicktime 7 Pro, it still runs just fine on Mountain Lion. Its not like Apple yanked it or 'dumbed it down' for fun-sies. Also social/cloud integration isn't crap, its where we are in contemporary technology.

You can thank Craig Federighi for this as he took over as Senior Vice President of Software Engineering after Bertrand Serlet left in 2011. Serlet moved to Apple with Jobs from NeXT and was Senior VP in S.E., and was mainly responsible for Tiger, Leopard and Snow Leopard. Criag Federighi is a hack, responsible for allowing Forstall to incorporate iOS **** into OS X while dropping the ball on improved graphics drivers and OpenGL Core support, a revised HFS+ Finder system, lack of full multiple display support, "Mission Control", horrible memory management, and pushing for an annual release cycle. The odds are, it won't change.

EDIT Read post #85, as some have called my information into question I have added links and facts to support that Craig Federighi was head of OS X development two years prior to Serlet's March 2011 announcement for departure. Craig Federighi has been head of OS X development since his return to Apple in 2009.

Wednesday, March 23, 2011, 08:35 am
Serlet joined Apple in 1997 and has been involved in the definition, development and creation of Mac OS X. Before his time at Apple, Serlet spent four years at Xerox PARC, then joined NeXT with Jobs in 1989. He holds a doctorate in Computer Science from the University of Orsay, France.

"I've worked with Steve for 22 years and have had an incredible time developing products at both NeXT and Apple, but at this point, I want to focus less on products and more on science," Serlet said.

He will be replaced by Craig Federighi, Apple's vice president of Mac Software Engineering. In his new role, Federighi will assume Serlet's responsibilities and will report directly to Jobs.

Federighi is responsible for the development of Mac OS X, and has been managing the Mac OS software engineering group for the past two years. It was Federighi who gave a live demonstration of Mac OS X 10.7 Lion at a media event last October.

"Craig has done a great job managing the Mac OS team for the past two years," Serlet said. "Lion is a great release and the transition should be seamless."

Federighi worked at NeXT, followed by Apple, and spent a decade at Ariba where he held several roles including vice president of Internet Services and chief technology officer. He returned to Apple in 2009 to lead Mac OS X engineering. Federighi holds a Master of Science degree in Computer Science and a Bachelor of Science in Electrical Engineering and Computer Science from the University of California, Berkeley.

Here's what needs to be fixed:
Issues related with Graphic drivers: Choppy Animations, Memory Leaks when apps use GPU/hardware acceleration, Kernal Panics.

Other problems: CRAZY Shutdown times, poor battery life.

Here's what should be added: GPU accelerated scrolling in Mail, Preview (similar to Safari), option to do a three dinger swipe in all apps when it's enabled in Trackpad settings.


Edit: I have a MBP 13" mid 2010. But I've also seen most of these problems on RetinaMBPs
