Apple Seeds Build 12D68 of OS X Beta 10.8.3 to Developers

Apple today seeded build 12D68 of OS X Mountain Lion 10.8.3 to developers, marking the tenth beta iteration of the newest version of Mountain Lion. 10.8.3 was first seeded to developers in November 2012.

12d68
Build 12D68 comes roughly a week after build 12D65. Registered developers can download the update on Apple's Developer Page.

This post originally referred to Build 12D68 as the eleventh developer seed of OS X 10.8.3 when it was actually the tenth seed.

This does not make any sense, what the hell are they fixing in a point release that needs ELEVEN betas??????


They're adding support for the 1:1 aspect displays shown in the graphic.

Thumb resize.

Do these betas include a new version of Safari that renders pages faster on rMBPs? (i.e. the "Webkit" version)


Admit it, you were too embarrassed to ask "Is Safari snappier?". :D

Sometimes it seems that Apple designed Mountain Lion just to increase their iPad and iPhone sales.


Usually it feels like you have no idea what you're talking about.

i rather have beta testers kill their machines rather than mines.

I know this is probably forbidden to say, but this type of update schedule is one thing that makes me miss the update format of Windows / Linux distros... It's been months since my OS was updated. With other OSes, you can at least hope for speedier incremental bug fixes. Right now there could be one single issue that is putting an entire plethora of bugfixes on hold. Is there some sort of benefit to this process that I don't quite understand?

Ugh the discussion here is so pointless. Doesn't anyone actually have anything relevant to add to the discussion?

I for one haven't been noticing really any differences in the last few iterations of the 10.8.3 beta.

Here's some things I've noticed so far while using the latest build.

- Bootcamp hasn't been updated to support Windows 8 yet.
I'm guessing that will be something that will come with the public release. I for one am really hoping that new boot camp drivers are released that fix some of the issues I've been having like no volume up and down overlays and problems I've been having with setting and adjusting brightness also keyboard backlight problems.

- Safari hasn't changed in the last few builds ( Version 6.0.3 (8536.28.10) )
From the standpoint of someone who doesn't have a retina display I see no reason to be using safari when both chrome and firefox are leaps and bounds better then safari.

- There is still a frequent indexing problem.
I'm getting re-indexing about every time I turn my computer on and then some...

- Shutdown still seems to be slow.
Can take a good 20+ seconds even with a SSD.

- Not really any noticeable changes that I can remember for the average user between 10.8.2 and 10.8.3
If you weren't noticing bugs in 10.8.2 then 10.8.3 will seem like nothing changed.

How big is the update file at this point?


The combo update is 830,201,394 bytes (830.2 MB on disk)
I think the delta is ~570 MB

Also, how long would the update take to install?


Depends if you are upgrading from 10.8.2 with the delta or a previous OS with the combo. It also depends on your drive read/write speed. I'd say it could range anywhere from 10 minutes to over 1 hour depending on your situation.

For me it takes about 10-15 minutes to update with each iteration. I'm on a 2010 13" macbook pro with a SSD.

Hopefully they will remove Game Center, is totally useless.


Game center hasn't been removed, in fact I believe it's slowly being tweaked and refined. The fact that it's relatively small (5mb) means that it's not really bloating the system for people who don't use it while still providing the beginnings of a potential mega-giant social game network for those who do use it.

If you can't handle seeing Game Center clogging up your Applications files simply open terminal and type what's displayed below and you'll never see it again:


sudo mv /Applications/Game\ Center.app /Applications/.Game\ Center.app


The point is that it is possible to render the pc useless by using beta/crappy software.

On the other hand I'm waiting for the 10.8.3 update to drop by to update my 2 macs. Let's hope they fix the inactive memory filling up all my ram and even making my mac page memory, it's getting tiresome having to run 'purge' every now and then.


Yeah, a OSX beta that's being seeded to developers probably isn't going to nuke your computer, especially considering that the software is taylor made for your hardware (unless you're using a hackintosh).

Why bother waiting for 10.8.3 to drop? You're one google search away from running the beta build which is, at this point, probably very very close to what the public build is going to be like.

Does the graphic enhancements of 10.8.3 improve chrome experience?

Maybe its just me but scrolling in chrome is much slower than safari on RMBP..

I hope RBMP becomes snappier in terms of graphics, thats my only compliant with my 13 RMBP


There is no graphics enhancements in 10.8.3 at least from what I understand. The mention of graphics drivers in the release notes is not about performance improvements but rather this:

As noted by netkas.org and in our forums, the initial beta release of OS X 10.8.3 seeded to developers yesterday contains drivers supporting AMD's latest 7000-series graphics cards, including the high-end "Tahiti" options. The development has naturally sparked speculation that Apple is starting to build in support for graphics cards to be used in the all-new Mac Pro coming in 2013.


Also Chrome is Googles responsibility not Apples. Chrome will remain slow on retina machines until Googles updates it specifically for retina machines. Apple has not control over this process.

Since I don't own a rMBP I can not confirm that there are no improvements from .2 - .3 but I wouldn't hold my breath if I were you. Performance is likely to stay very much the same, this is a release that I believe is mainly focused on small bug fixes and tweaks to existing apps.
