Mac OSX Mavericks 10.9 firewire audio problem on RME Fireface 800, MOTU 828 Mk II and Apogee Duet on late 2013 iMac i7

Jyst to add my experience. I have a Presonus Firstudio, New iMac with Fusion drive. Before upgrading to Mavericks, no problem. Worked a treat.

After Mavericks, the sound cuts out after a few seconds. I tried the Precent App Nap, trick, but without success. Sound output through the headphones socket - no problem.

I have the exact same issue with my Apogee Duet USB and a brand new CTO iMac 21" (Late 2013) i7, Fusion drive 1TB.

Audio pops, clicks and gets choppy after 5-10 minutes or so.

I've completely reinstalled my OS, flashed the duet firmware, reinstalled the drivers, issue persist.

I also have a MacBook Air Late 2010 running Mavericks, no issue at all with my Duet.

Is everybody that has the issue have a fusion drive ?

We need a fix ASAP for this issue !

Another point is that others are having similar issues without the fusion drive. I would suspect that it is more of a OS issue. Niote above that one person had the same issue and that he had a mac mini. No fusion drives there. Peter

I have an USB Apogee Duet with the current Apogee Maestro 2.8.8 driver and I get the same issues. I have a new Late-2013 iMac 27", 3TB Fusion, 32GB RAM. I just left a bug report on the Apple Feedback page.

Yup, that's the same: worked fine with 10.8 and the Fusion drive. So it's pretty clear that the issue is with Mavericks and the Fusion drive.

Surely Apple are addressing this? Surely?

Mac mini reporting in, I sold my Motu 828mk2 and got a focustrite saffire pro. Everything works very very well. Hope this helps

Since I have sold my 828mk2 and bought a Focusrite pro 40 and everything worked straight away with no problems at all, very very little latency.

Same than Petegorilla , I got the edirol FA-101 and I got issues when using Ableton and letting Itunes on, there is like an audio routing conflict , and ableton won't play the sound on my soundcard. There is so much workaround with Maverick that it brings me back in time, when I was using windows vista. Vista being the trigger for me to switch to apple. I wish sometimes some programmers with musician roots or background , will start to make an OS dedicated to music Use.

I have exactly the same problem: brand new iMac 21" i5 fusion drive, presonus Studiolive firewire and RME Babyface USB... No problem with my old macbook pro with maverick as well. Woul it be possible to install an older OS until apple has solved the problem? Marco

I agree that Apple should fix the problem and should not have released these machines/OS with issues such as this. I was just restating workarounds that have been discussed in other forums that folks can try until this problem is fixed by Apple.

This problem is impacting many people's ability to make revenue. For those, they may not have the time to wait for Apple to fix this issue. So for those, attempting a workaround may help them until Apple get's their stuff together.

any luck getting your Motu 828 Firewire to work? I have the same setup as you and also have the Motu MidiTimePiece A/V. I'm totally scared to upgrade to Mavericks. Apple is notorious for using us as their beta testers instead of actually making sure it works.

Can you roll back to the old OS X?

What a pain/scam I think they are trying to force you to upgrade when you had a system that worked fine?

What's the deal? Maybe MOTU will release an update or patch to fix this issue with Mavericks.

Until then I'm going to have to avoid Mavericks b/c it will destroy my recording studio!

I have the exact same issue as you guys. Brand new Imac - 3t fusion drive - i5 3,2ghz - 16g ram - edirol FA101 popping... and I just opened it. I had no issues like this with my late 2008 macbook pro running mountain lion (with a 250 g ssd inside) . I am not ready to try any weird manipulations with the fusion drive since I paid for it. Apple has to fix this issue asap. This is absolutely not professional and not acceptable for such an expensive computer that is supposed to be way reliable than a windows running one... and evenmore when music production is your job and that you ll loose time and money because of apple's lack of expertize. I don't even want to spend hours to explain this issue to their "supposed" experts because I know they will propose me to buy another soundcard ! This is indeed an easy way to solve problems.

Same issue here... Brand new iMac 3.5 ghz i7/3TB Fusion Drive/ but with an RME UFX... I had the ram upgraded after the fact with 3rd party ram and I was pulling my hair out thinking that the ram was messing my audio up? I loaded the original ram and the issue continues... Kernal panics, core audio crashes, glitching audio, audio completely crashing when listening to mp3's streaming radio, youtube...

I did intend to use this computer for music production in my studio... looks like i'll be using my macbook again...

Should I return my iMac?

It must be machine specific. I have the 828x and a brand new ( Feb. 14) MacBook Pro (love it) and it works fine in Thunderbolt and USB 3.0.

Sorry, I know that doesn't help but at least I thought it would help with what machine works and what doesn't work.

OK, it is NOT working. I can jam for about 5 minutes or so and then POP . . . . . it shuts down. Then I just need to pull up the volumes on the MOTO Cue Mix and it works again for 5 - 10 minutes. What is going on?
