OS X Mavericks Update Is Causing Sound And CPU Memory Issues For Some Users

Apple Mavericks Audio and CPU Usage Issues

The Apple Mavericks OS has been highly touted as a superb update for the Apple Mac line of devices. While most users, this author included, have found the OS to be worth the free upgrade, some are also experiencing a strange sleep-mode issue.

A slew of Apple Mavericks users are reporting that their computers no longer play sound after they upgrade to Mavericks and then take their computer out of sleep mode.

The problem appears to be occurring on 2013 Macbook’s and various threads regarding the issue are popping up all over the internet.

After the Macbook’s lose sound users are not able to turn the audio back on.

Other users are also claiming that the OS X Mavericks upgrade is causing their CPU usage to be eaten up and system logs are showing the following error.

After my own upgrade my 2013 iMac started experiencing the very same CPU issue. With only Firefox and Sparrow email running I am regularly consuming 7GB to 7.78 GB of RAM use on an 8GB machine. My issue is resolved by a quick restart but then appears again after a short period.

The issues appear only to be affecting Haswell-based MacBooks, which includes the MacBook Air that was released earlier this year.

The audio issue has been solved by some users who have inserted and then removed headphones and by restarting their laptops.

You can also reset your PRAM but keep in mind that completing this process incorrectly can cause you to lose everything.

Apple has not commented on the Mavericks issue for audio problems or high CPU usage at this time.

Have you been experiencing any OS X Mavericks related upgrade issues since you made the free leap to the new Apple OS?

    Yep! I have been having issues with speed of computer and Safari since the update.

    Yeah I am using 3.7 out of the 4GB of ram that my machine has with only Chrome and iTunes open. Before Mavericks this would only use about 2.5GB

    My audio starts popping and clicking after about 5 minutes every time. The only way I can stop it is by restarting my brand new iMac, but it happens again. I've just invested in a pair of KRK monitors and they sounded fine before the update. I'm inclined to think it's something to do with the Mavericks having compatibility issues with some audio interfaces because I'm using an older modelled M-Audio Fast Track and someone I spoke to this morning at my university said they were having the same problem. If this is the case, it's a massive inconvenience for me – I've just invested in £1500 worth of equipment and I'm getting clicky/poppy monitors. Apple needs to hurry with a solution. :-(

    Yep. I've got no sound for Google All Access or for Soundcloud on both my iMac and my Airmac, both bought 2 years ago. No resolution yet. And I've got the same CPU suck problem.

    So no upgrade for me. Although my current MacPro has all sorts of weird problems, such as refusing to go to various websites. Since getting a Mac, I've been thoroughly unimpressed with their vaunted technology and supposed ease of maintenance.

    I bought and returned a late 2013 iMac (with fusion drive). I had audio issues : pops, clicks and sound distorsion with my audio interface (Apogee Duet Firewire with thunderbolt adaptor). I am musician and couldn't do a clean recording. I don't know if it is a mavericks issue, a late iMac issue, a Fusion Drive issue. i read everything and its opposite. It's not clear. The only thing I know is that the issue has not been fixed.

    Non c'est celui que j'ai renvoyé. J'attends de voir le problème réglé avant de recommander. Mais comme l'origine du problème n'a pas l'air très clair. C'est pas gagné. Je vais peut être me prendre un mac mini. C'est qu'on a une BO à faire bordel !
