  • Otrax Level 1 Level 1

    I have a 2008 macbook pro and the sound stuttering persists even after the 10.8.3 update! Whenever I open itunes, spotify, soundcloud, youtube etc. it skips as if it were a cd player being dropped on the ground. I cannot listen to music at all like this. 

    One more note: It's worse when my volume is maxed out.

    Can anyone help with the OLD macbooks?


    Here's my computer's info:


    Processor: 2.93 Ghz Intel Core 2 Duo


    Memory: 8 GB 1067 MHz DDR3

    Best thing you can do is request apple take it back or sell it off and go buy a PC.  They don't care as evidenced by the amount of time this fix took and the amount of screaming to get them to even do anything like betas.  If you can, list it on criagslist and buy a new PC that actually gets support. 


    Unsubscribing from the thread as this doesn't pertain to me anymore.  But lesson learned, I'm taking my business elsewhere.  Apple also has a class action suit against them for the Retina displays having image retention too, which is another area they knowingly have abused their posiiton.  Not to mention their drones who scour the threads to censor this stuff from innocent and unsuspecting eyes.  9to5, appleinsider, and mac rumors don't censor there which is a great source and google frequently pulls them in searches for problems.  You might try researching their discussion boards for a more unbiased reporting than the apple sided posts here.  Good luck!

    My sound since installing 10.8.3 is stuttering all the time now.  I had not noticed the problem prior to installation.


    I had noticed a terrible stuttering problem with typed characters appearing on the screen and with video downloads stalling for seconds, but not audio ... until now.


    By the way ... the stuttering key to display problem still exists as does the video download problem.  10.8.x was not Apple's finest moment.


    I have been working with multiprocessor, multi tasking operating systems since the early 1980s and this problem existed then... its always traced to the manager routines getting lost.

    I did the upgrade last night and so far the audio is fine, the real test will come tonight when I try to watch a full movie after my iMac has been running for more than an hour! (maybe and hour of Starcraft II as well)

    Fingers crossed that this actually fixes this problem.

      I am also amazed that they mention the Audio Stutter problem on the list of fixes for 10.8.3

    Also I am wary of buying whatever new OS they come out with this summer and will be skimming these boards for problems that might make my 1 1/2 year old iMac run like something from 2005!

  • dokt Level 1 Level 1

    Just to follow up my pre-update post. I have now updated, and so far so good. I haven't done the ultimate test (play starcraft) yet, but so far video and sound have been working 100%. Im on a 2012 iMac.

  • Chris Vice Level 1 Level 1

    iMac i7 27" late 2009 and still stutterin with 10.8.3. I waited 6 Months for this update like an idiot and tried everything, I've reformated my whole System a dozen times and now this. I'm actually thinking about throwing this piece of **** out of the window. The moment I've read that the audio fix is for the newer iMac's i knew it. Apple, i give you one last chance .... fix it!!!!

    What are you using to benchmark that?

  • Chris Vice Level 1 Level 1


    sudo latency -p 97 -st 2000 -it 2000 \

         -l ~/Desktop/latency_YYYYMMDDTHHMM.log



    ctrl + c to stop it (facing terminal)


    I will go back to Lion now, I hope they resolved the WIFI dropping with the last update for Lion, that I had in the past (that already drived me crazy). I always recommended Apple Hardware and I'm starting to regret this. My last chance I give them is 10.9.

    Delays with Mountain Lion only when playing Music (iTunes, Quicktime, Youtube, ...)

    Thanks dude


    I always love cool new terminal lessons

    Another data point: my Mid 2010 27" iMac, 2.9 GHz i7, 12 GB, continues to stutter with a completely fresh install of 10.8.3 when doing nothing but run iTunes.  FWIW, I'm still on iTunes 10 as the interface simplification of 11 is "broken".  Back to 10.7.5...

  • jimoase Level 1 Level 1

    Consider playing around energy management selections as having an impact of stuttering.


    I'm using a MacBook Pro 17inch with 16 gigs of RAM.


    Stuttering changes when I change Computer Sleep and Hard drive sleep. 


    My testing is just beginning... more tests by others will speed up the evaluation.


    Turning off any sleep directives, while battery powered or adapter powered, seems to decrease the frequency of stuttering.  There are other penalities when sleep is turned off.  Right now finding the source of stuttering in prioritized.


    What is your experience?

  • M-6 Level 1 Level 1

    I've been on this thread since page 45 and discovered the thing that fixed my mid 2009 13" MBP (running 10.8.2) was turning off "show icon preview" in 'finder > view > show view options >'. I'm reposting this as I would never bother  with re-installing the OS when so many people have with no luck. This thing is a weird moving target and I'm actually going to wait to update to 10.8.3 for fear of breaking what is working beautifully right now.


    I guess one major detail is I'm not running a DAW on this machine yet (that's on my SnowLeo MBP which I will never upgrade), but iTunes was being hosed consistently until I turned off the icon preview. I hope this helps...

  • D M K Level 1 Level 1

    Since installing the 10.8.3 update, my audio stutter problems have completely gone.  It's still really poor that Apple have sat on the fix all this time.  Apple - if you break something, FIX IT.
