Apple Seeds Build 12D54 of OS X 10.8.3 to Developers

[MacRumors]

Apple today seeded build 12D54 of OS X Mountain Lion 10.8.3 to developers, marking the sixth beta iteration of the newest version of Mountain Lion. 10.8.3 was first seeded to developers in November.

Build 12D54 comes just eight days after build 12D50, and like the previous build, contains no known issues or features. Build 12D50 brought only minor changes, and asked developers to focus on testing AirPlay, AirPort, Game Center, Graphics Drivers, and Safari.

9to5Mac notes that the new build contains significant changes to WiFi, but additional changes are unknown. Registered developers can download the update on Apple's Developer Page.

This post originally referred to Build 12D54 as the seventh developer seed of OS X 10.8.3 when it was actually the sixth seed.

They're really testing this one thoroughly.

Hopefully, 10.8.3 will fix the crashes when switching graphic cards

This bug exists since (Mac) OS X 10.6.0. Why do you think they fix this kernel bug in 10.8.3?

10.8.3 supports the new Thunderbolt Displays and/or the new Mac Pro. Hints are the new Fresco Logic PCIe to USB 3.0 bridge drivers and new AMD drivers.

OS X updates come always after the printer driver updates (usually 2-4 weeks later). See:

Hi, vmachiel. Could you (or anyone else reading this) please explain what happens during those crashes when switching graphics cards? I mean, what do you see on your computer screen when such a crash happens? Is there any kind of message that appears on the screen?

[newfoundglory]

Just for some fun - with Terminal of course.

sudo su -

cd /Library/Preferences/

mv com.apple.SoftwareUpdate.plist com.apple.SoftwareUpdate.old

touch com.apple.SoftwareUpdate.plist

/usr/bin/defaults write /Library/Preferences/com.apple.SoftwareUpdate.plist CatalogURL "https://swscan.apple.com/content/catalogs/others/index-mountainlionseed-mountainlion-lion-snowleopard-leopard.merged-1.sucatalog.gz"

check software update still works

I just hope it will be released by tomorrow - on the other hand, Apple really seems to be working hard on this one so it could be worth the waiting....

Hi there,

I use istat menus, and what i see when the graphic cards switch is one thread of one processor core gets fully used up for about 15 seconds and then the whole systems freezes. It mostly happens when I try to scroll through a web page really fast, or when I open a folder with 50+ files in it that the system tries to preview.

When I reboot and look in console, it always has the same lines in it regarding nvidea and opengl. When I turn off auto switching of graphic cards in system preferences, I don't have any crashes. When it is on, my system crashes every week or so.

Do you have similar problems?

My 10.8.2 issues:

1) SLOW SHUTDOWNS

2) Poor battery life (2-3 hours, max, on MacBook Pro w/ 92% of original battery capacity)

3) iCal randomly gives errors with Google calendars.

I've seen no changelog (anywhere) that mentions those being addressed.

Try to go into Disk Utility and Repair/Verify Permissions on the HDD. As for the battery, try to calibrate it if you haven't done so recently. Use it from 100% then drain it completely to 0% and then charge it back up to 100%.

I actually have all of these issues too

This is caused by Google I think. As far as I can tell, Apply is fully compliant with calDAV. It's google which is fussing with something.

They always release in mid 50's or low 60's build numbers.

I'm a super happy ML user.

The only thing that still bugs me is the occational blue-colour-tint when switching graphics cards (on my almost brand new non-retina but hires 15" MacBook Pro). Hopefully, this will be fixed with a new set of updated graphics-drivers.

Are you using some 3rd party app (Chrome, looking at you) that constantly kicks in the dedicated GPU and ruins battery life?

Try gfxCardStatus and force it to stay on Integrated only.

With every new build, the hope for big improvements becomes stronger!

GO GO!

Such as?

[adnbek]

Did they fix the issue of Notes deselecting itself within iCloud settings at random?

[ultraspiracle]

no ML for me (again) till the shutdown time is brought under control to something reasonable. This kills solid state and retina MBPs. I went back to Lion - solid, stable.

[koban4max]

You guys should send feedback to apple... if apple didn't fix it..that's because it's your fault of not report... sounds like unreported rape.

I had this exact issue, couldn't figure out what was causing it. Apple Genius told me as a last resort to reformat and load all the stuff back onto the HD from scratch. Problem solved.

Funny, I get the iCal errors randomly too. No idea why..

1) I was experiencing the slow shutdown on my MBP. Searched everywhere for a solution. After booting in verbose mode, I saw a process was hanging. Followed instructions here (3 terminal commands) and now have two second shutdowns.
