Q: Sound stuttering after Mountain Lion install

Thanks Apple!

They are clearly taking action on this issue now.

No love here. Ill just be glad it gets fixed. They've already replaced my LCD and GPU on my 27" with 2048 as it was fried.

Finaly! I have a iMac 2011 and installed yesterday de 10.8.3 Beta! Everthing works now nicely and smooth! nomore of  stutter, lags or kernel panic!

I just wrote in my post above that I would only install 10.8.3 as an official Beta tester or when the version is released; but not illegally (via torrent,etc…)

And the result: I got an invitation

But sorry, I am not allowed to write something here, since "THE INFORMATION IN THIS EMAIL IS CONFIDENTIAL - DO NOT FORWARD"

An update appeared today for June 2012 MacBook Pros which I've just downloaded with the hope that it might solve the problem but the stuttering is worse than ever - taking over 20 minutes to play a 5 minute song!

Plus now frequent lock ups (with beach balls) and an age to switch applications.

I'm glad to hear that those of you with 2011 iMacs seem to have the problem resolved with the 10.8.3 beta but I've had the problem with a different machine and graphics driver - is there anyone on the beta with a mid-2012 MacBook Pro who had this problem and, if so, can you confirm if everything's working well?

Apart from the fact that my Mac is unusable, I'd just like some assurance that there is a light at the end of this particular tunnel.

I have the same issue since I've installed Mountain Lion on my iMac late 2009 27" i7. I'm Apple user for quite some time now and paid a lot for all these devices and this is the first time (also including that I can't reset my security questions) that I'm really frustrated. I use this machine for sound production and it's unusable since 2 months now. I hope they will release 10.8.3 as soon as possible because I don't want to use torrents as I don't have anything illegal on my machines and I don't want to start with it because of this.

It's not only the sound stutter, my iMac is so hot that I can use it to heat my whole aparment.

I never want to go back to windows my history is: DOS, Windows NT, 95, 98, 98SE, 2000, ME, XP, Vista, 7, Leopard, Snow Leopard, Lion, Mountain Lion.

Leopard and Snow Leopard was the greatest thing ever to me, but also Lion gave me a lot of issues (WIFI connection loss), they really need to start getting back on track with OSX.

OK wow: IS THIS A DREAM?

Mac OSX 10.8.3 really fixed our issue! I can run Minecraft, Xonotic, Xcode, Motion, iMovie… AT THE SAME TIME and get 0 stutters in EyeTV and 0 stutters in iTunes!

This is so mamzing! Thank you very much!

But hey, this updates comes half a year too late^^

And to top it of: The machine seems to stay a bit cooler than in 10.8.2…(you can touch it without burning your hand^^)

so...when will this 10.8.3. be available???

this is soannoying I might consider a torrent =)

I would very much like to see if the beta fixes this issue for me (2011 iMac user)

Just adding my experience to the stew: I very cautiously upgraded my mid 2009 MBP 13" from SL to ML this week and have been very pleased with the results. It's actually made my computer faster, which was a huge relief after all the CPU lag/fan issues people have been having. So I stand as proof that a mid 2009 MBP w/ 8GB RAM & a hybrid drive works great. That is, until last night: iTunes has started stuttering. Total drag. It's not terrible, but it's happening, especially when I'm using Mail. I'm glad to hear the 10.8.3. BETA has been fixing this for people.

Apple, release the bats! I need my iTunes like the babe needs the teat.

that's all well and good but I don't have access to 10.8.3 and apple's support has been completely unhelpful. I just had a rep last week tell me to use capture data and he said he was going to call yesterday but I got no call, no response to my voice mail, and I sent another email today which also got no reply.

the last time I brought my computer to the apple store they were pretty rude to me and gave me back my computer with chipped glass (which I still haven't bothered to fix since it will cost me $50 to get my computer to the apple store and back in a cab). they also said I had no sound problems and basically called me a liar.

needless to say I am extremely frustrated and would have ditched this machine for windows if it were feasable to do the work I do without using OS X (it isn't)

I agree bms82, that is the reason why I havent' reinstalled ML and taken my iMac to the Apple Store, it's too big to take on the bus, I'd have to use a Cab!

  And once again, shutting the iMac down for a while and restarting seems to cure the Audio Problem, unless it is running for about an hour or so, then the sound problem is back!  I doubt I'll get anyone patient enough to listen to my machine for that long!  It will sound great for a while, but when I get it back home and get past 1/2 hour of a TV show, Movie, or Music, then the problem will return!

  I truly hope this possible update is going to fix this problem, we have had enough waiting around with our big iMacs and all the great potential the possess, just to have the new OS make them sound like a cheap AM radio getting bad reception!

  One other interesting thing, If Apple doesnt' want to acknowlege there really is a problem with our machines and the problem software, why is there on-going editing of this discussion?

  How many times has someone seen their posts deleted?

Let's get this 10.8.3 ready, and Fix Our Problems!  my iMac is far too powerful to have to be relegated to the last OS just so everything works properly, when all I want to do is use the newest most up to date version!

  Why does my i7 iMac with 2GB of video power and a 1 TB drive choke on Mountain Lion when it is perfetctly fine on Lion and Snow Leopard?

-_-

I haven't recieved any kind of word from them on letting me beta this.  It's rediculious.  Post the beta or post the final version.  6 Months, 6 MONTHS!!!!

You've been a very very bad boy BarretF77. Now your gift will be given only at christmas or after it, as it's for the other bad guys.

What do you propose, spanking me?  (I might like it)

Apple needs a few good lashings, Singapore Gangham Style!  They instigated this mess.
