Apple Seeds Build 12D61 of OS X Beta 10.8.3 to Developers

by

update12d61Apple 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.

Because Mountain Lion is more buggy than Lion at this point in time. Are you actually unaware of that?
It is not. ML runs amazingly well and Lion is the one that sucks. It's your system that you need to work on.

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.

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

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.
