Apple today seeded build 12D61 of OS X Mountain Lion 10.8.3 to developers, marking the eighth beta iteration of the newest version of Mountain Lion. 10.8.3 was first seeded to developers back in November.

Build 12D61 has been released less than a week after build 12D58. The new build asks developers and testers to focus on AirPlay, AirPort, Game Center, Graphics Drivers, and Safari.

As with previous builds, Apple mentions that it has significantly improved WiFi performance, as noted by 9to5Mac. Registered developers can download the update on Apple's Developer Page.

This post originally referred to Build 12D61 as the ninth developer seed of OS X 10.8.3 when it was actually the eighth seed.

As much as I want to ditch 10.7.5 Lion, I am hoping that Apple takes their sweet time with the 10.8.3 update. I don't care about new features since lack of bugs is most important thing for me.

Then why on earth are you still on Lion? ML is far more polished, which you've certainly read a couple of thousand times.

I was going to ask the same thing. Who in their right mind would stay on Lion? You either come to ML or go back to SL.

My old MacBook Pro only goes up to Lion.

I want Notes and iMessage. :(

I can't go to Snow Leopard, because I would lose support for the latest Xcode!

Has it fixed the slow shutdown? What about settings options having to be launched twice such as change desktop background?

Great news, but I hope they fix the problem where every time I restart my rMBP the background changes back to the last one I had.

It is not. ML runs amazingly well and Lion is the one that sucks.

Mountain Lion might run amazing well for you, but for the majority of users, 10.7.5 is more stable and reliable than 10.8.0, 10.8.1, and 10.8.2. Yes, Lion does suck, and Mountain Lion has the potential to be better than Lion, but as of 10.8.2, Mountain Lion still has far more bugs than 10.7.5.

It's your system that you need to work on.

For your information, I own the latest 13" MacBook Pro, and it's maxed out with 16GB of Crucial-brand RAM.

I don't think you actually speak for a majority of users.

This is just pure false. ML is far more stable, more secure, and faster than Lion by a wide margin. Frankly, I'm pretty shocked to hear anyone suggest otherwise. ML's vast superiority to Lion is pretty well documented fact by the vast majority.
