Q: Mavericks 10.9.2 out... Audio issues fix included!

A long odyssey appears to have ended.

I had "un-fusioned" my 3TB fusion drive. After the 10.9.2 update, I re-fusioned, reinstalled, and all seems to be performing well. (Still have USB3 port issues though; e.g., my 2 Seagate usb3 external drives will not boot off the on-system ports...had to run the drive through a USB2 hub to get them to boot the machine. I also have to run my Steinberg UR824 through a hub as well. Argh...)

Anyway, audio problems appear to be sorted out, and I had them bad.

For those who need to do this, the "re-fusioning" is easy. Boot to the recovery partition by holding Cmd-R during boot. Open Disk Utility, and it will be showing a problem. Click on the drive and it says, "Your fusion drive is not installed properly. Would you like to fix this problem?"

BE WARNED: This is a destructive change, so you better have backups.

After you do it, if sets the drive back to "MacIntosh HD" with no bootable os partition on it. At that point, I booted off my external drive (in a USB2 hub of course), and then just ran SuperDuper to clone it back to the fusion drive. (That took almost 24 hours to complete, but once it's done, it was a simple reboot and all is well.)

What a nuisance and soul draining, disheartening Apple experience this has been. But on the other hand, it appears to be fixed.

Thanks to all who've shared the info we've needed to get through this, esp AoS.

NO! 10.9.2 has done nothing to repair sync and 'clicking' issues either in YouTube or .mov or m4v. Aren't these updates beta tested? It's totally unacceptable.

Give all your specs please: Mac ?, Logic Version, Audio interface, cables, adaptors etc... All please!

Actually, I have to rescind my machine's clean bill of health after a bit more testing.

The extreme decimation of sound is gone, where sound gets nastily pixelated, but I am getting quite a bit of popping and noise in recording and playback in Logic Pro X and FCPx as well.

@#&$^&@. This machine is cursed.

It is: Late 2013, i7, 3TB Fusion disaster drive, 16gb ram.

Very possible. I have an FW interface I can try, so I'll I do a few experiments to see what if I can get better results there. I haven't run through the full complement of different USB and my Tbolt hubs. That's the next thing to try I guess. I'll let you know if I see anything interesting but it might take me a couple more (wasted) days to try out some of the combinations.

Sigh.

First of all, TAOS, your help is greatly appreciated here. Thanks a lot for your implication.

Well, maybe for the one using a 2013 Haswell mac all is fine now and I'm really happy to hear that, at least for the one using a FW audio interface, but I use a late 2012  (w/ fusion drive) imac with ivy bridge processor, using firewire 400 audio interfaces, through a thunderbolt adaptor and a FW 400/800 cable and still have issues. See my post(s) above for more details.

Things got really better though.

"The feedback I am getting is mainly from those with FW devices.. and for those people, in every case so far... 10.9.2 has resolved all audio issues... after extensive testing by them."

Not anymore. I am using Apogee Duet FW, and still have popping and clicking during iTunes playback. It's not nearly so bad as it was before, but it is still highly irritating (and inexcusable).

I give up. I am now stuck with an almost $2,000 lemon. My next computer almost certainly will be a Windows machine (hope someone from Apple is reading this).

Thank you very much, Art of Sound. I had not heard that from Apogee. The technical support person with whom I corresponded said he would keep me updated, but hasn't...surprise, surprise.

Thank you again for keeping abreast of all this and providing better and more up-to-date information than the companies do!

"but the new 10.9.2 ones, so far, seem to completely nail the problem regarding both USB and FW... from the feedback I am getting..."

Your talikng about Apogee FW audio interfaces and 2013 Haswell imac I presume because 10.9.2 is still ba little buggy,  at least for me.

"Thank you again for keeping abreast of all this and providing better and more up-to-date information than the companies do!"

AppleCareadvisor ever told me that eveything was fine with 10.9.1. Always the same answer was " If everthing is fine using the built-in audio, then the problem is not on our side... And now, all would be fine because of 10.9.2 ????

Come on Apple, your not seriuous at all.
