Sound stuttering after Mountain Lion install

I also have the 2GB 6970 iMac and had unbearable sound stuttering, beach balls and graphics glitches.

I've installed the 10.8.3 beta and all problems seem to be gone. I'll be sure to update if anything comes back.

For any Apple spies that may be monitoring this forum, I don't care the slightest about breaking any NDA, copyright law or whatever. This problem has been very frustrating and unbearable and should've been fixed much earlier.

I agree. I don't really care about any Apple policies anymore. I advocate in both business and personal for my contacts to avoid Apple computers now at all costs. I post evidence of these issues on social media, and every other outlet. They have no respect for those who got them here. As a result I applaud the day they return to a struggling company.

I don't agree completely because of one thing. They have contacted us.

I wonder if the same happened to microsoft for example, whether they would have contacted us directly because of an open forum.

Although I think microsoft may be faster solving such outstanding issue cases, the direct contact is remarkable.

Pepper, you need to stop drinking the kool aid. I called them after this one week time where they would give an update. Have done so numerous times. Since then, they have not acknowledged the problem exists and wanted to do general troubleshooting. The service is arrogant and they don't communicate. End of story

And do you know about microsoft for example?... In this case, I know people sent their devices for analisys and received another in place. I'm not sure about the competition, how would it deal with it to compare. I know of the "arrogance", but it's everywhere. I'm comparing from bottom-up, not up-bottom.

I'll put it this way. With Windows I can install my own drivers and have more say over my computer. With Apple you are at the mercy of them to "make it just work". They have fallen so far short of this mark and the price we pay for these machines there is no excuse that is acceptable. They haven't even apologized for it. It's our dollars and time that is being wasted by this. And Apple would never take my machines and replace them, so that's a moot point. At least windows makes my mac run better than Mountain Goat. Pretty sad to spend all that money on pretty hardware and then have to resort to Windows. But I suppose the beauty of windows is it actually is stable. It can play music like my $100 iPod and not stutter.

Instead I've got two dozen hours plus on the phone troubleshooting and another dozen just wasting my time talking to someone who doesn't have a care in the world about resolving the matter. Unless they right this with me I'm finished with them. It's so disheartening how they handle these matters with silence that it is deafening. I won't ever forget this.

I will be curious if the log notes say anything in 10.8.3 about this update fixing the issue or they secretly slip it in. Apple is two faced in they portray themselves to be one thing and are a completly different beast on the other side of things.

Hello,

I got the 2011 imac and the same stutter problems, but I hope and believe that there will be a fix in 10.8.3.

In every article about 10.8.3, I read that the beta testers have to pay attention to airport, airplay, gamecenter and GRAPHICAL PERFORMANCE of the osx (driver issues). So lets hope that all will be fixed.

Any information when we can expect 10.8.3 to be released?

Has anyone access to the developer preview and can report something?

"Graphical Performance" sounds great 😀 … this would also explain why eyerything works fine with bootcamp -> Windows…Microsoft has better driverrs!

I'm tempted to get a torrent and try it. Apple should post their updates like Nvidia. They have channels you can get beta video drivers from Nvidia. And since OSX is a beta anyways, why wait! I would guess they release it either before Christmas by a week on case some critical issue is found or they wait till mid January.

I'm tempted too, but I can't risk it on my production machine. Looks like 10.8.3 is just under half a gig, that's alot of data which could be buggy, especially considering it's only the first beta release.

Probably will do the same. It's not worth screwing it up more than Apple has already managed to do. Waited this long. Also talking to executive relations about this. Squeaky wheel

Just formatted my hard drive. Wiped it clean, and installed Mountain Lion over the clean drive. So far no problems. I imagine I'm not the first one in this discussion to try that. Correct?

yep…wait a few days and the stuttering will return 😟

This issue can be frequent or elusively sporadic. It looks like a graphics driver issue, so try using iTunes consistently for a few days with your normal workflow and I dare say the problem will likely resurface. I know there are others who have posted here saying re-installs had no effect long term.

Just to add, my ML install was cleanly installed over a zeroed HD.

Wow, apple just emailed me and offered to participate in 10.8.3 beta to fix issues regarding audio. I'm surprised they do try to fix.
