12d61Apple today seeded build 12D65 of OS X Mountain Lion 10.8.3 to developers, marking the ninth beta iteration of the newest version of Mountain Lion. 10.8.3 was first seeded to developers in November 2012.

Build 12D65 comes exactly one week after build 12D61. As with build 12D61, build 12D65 continues to ask developers to focus on AirPlay, AirPort, Game Center, Graphics Drivers, and Safari.

Registered developers can download the update on Apple's Developer Page.

Update: According to 9to5Mac, the new build fixes the file bug that recently made headlines.

This post originally referred to Build 12D65 as the tenth developer seed of OS X 10.8.3 when it was actually the ninth seed.

Shutdown times appeared faster a few builds back, but seem slow once again. Although, they don't appear to be as slow as 10.8.2.

I'm seeing a few new bugs I haven't seen in previous builds.
I had duplicate cursers on my screen a moment ago.
Every time I log out, the desktop picture freezes in the middle of fading to the fabric background of the Login Window. Very jarring.


File a bug report.

I hope that after they release 10.8.3, they release an update to Bootcamp so I can install Windows 8 (with full support).

I wonder if they'll fix the huge Safari memory leak, or maybe allow it to display animated gif without it going nucking futs all over the screen.

I hate to say it, but "this". Safari is a damn wreck. On the 4 rMBPs I've used, all four have the gif anomalie above, as well as wrecked CSS rendering on many websites, and going back a page yields a white screen. It's so bad that I use the slower, clunkier Chrome as my browser of choice. The thing is, internet browsing comprises the vast majority of people's computer usage, so why these problems still exist is beyond me. I have a hard time caring about slow boot times when I currently find web browsing to be more fun on my phone than on this $2k machine.


Don't even get me started on the CSS rendering in Safari. Things jumping around the page and disappearing as if a tiny poltergeist has climbed inside my computer and is having a fit. You think a program like Safari, which after a few hours of browsing takes up 2GB of RAM would at least be able to render the things I wish to look at correctly.

My main problem is that there is just no alternative that stacks up to Safari on a Mac. When I had a PC, I loved me some Opera, but not so much on the Mac. Now I have to just sit there and suffer random anomalies and page breaks.

The only bug I care about is one that happens when I use Transmit and Textwrangler. If I open a file off an FTP server, edit it and save it, I have to quit Textwrangler before opening another file from Transmit. If I forget to quite Textwrangler, Transmit freezes. This is a bug that started happening when 10.8.2 was released.


Textwrangler has a builtin in FTP and SFTP functions, try using that. It has streamlined my work considerably.

10.8.3 beta already has support for Windows 8 in Bootcamp... doesn't it?

----------

I have the feeling that this long-awaited 10.8.3 is gonna cause MORE problems than what it purports to fix...


Based on what? A long beta period (with lots of iterations) like this is usually a good thing.

clunkier Chrome as my browser of choice.


Clunkier? I guess that's why Safari, Firefox and IE have all completely ripped off the uncluttered and simplified Chrome UI then? :rolleyes:
