If you guys want help with your logs, make sure you send them to support@ableton.com, they won't do any good just posted here in the forums. Thanks!

[florian_bl]

I had to deal with this problem for nearly a year (OS X Yosemite) and Ableton's support couldn't find out what was going on. Then I had contact with another user who had the same problem and we solved it for us without the support involved:

Before the messages disappeared, I had wiped my hard drive several times. Always with a clean install afterwards. The problem returned. The last time I forgot to install Melodyne Editor again. Suddenly the console messages were gone. The other user that I mentioned tried it too. Same result. Our computers are okay now.

One time I did a reinstall of the OS but copied my user account with the Migration Assistant. Without reinstalling Melodyne the problem came back. It seems that something in the OS X user account gets corrupted by Melodyne and the problem will return if Migration Assistant moves old user data to the newly installed OS X.

[fishmonkey]

interesting. i also have Melodyne installed. did you report this to Ableton and Celemony?

[florian_bl]

Not to Celemony. Ableton got informed from the other guy who still had an open support case when we found out.

[parking sun]

Amazing work, florian_bl.
I have Melodyne too, so I guess this is a strong candidate.
witchbutter, I noticed that wasn't on your list of candidates. Did you miss it by any chance? (II have izotop too, but different versions)

I notice the entire celemony website is down at the moment in preparation for their new software version release. My guess is that the odds of them pushing a bugfix out any time soon are very low, hm?

Assuming it is melodyne, It would be nice to know what in fact Melodyne breaks so I can fix it manually without a complete rebuild; because I've rebuilt this computer a lot recently, and now I'm on tour to Indonesia and rebuilding it again is going to be a nightmare.

[nicfromcannes]

Hello
Glad I found this thread. I encounter the same flooding problem, and I have as Melodyne singletrack 2.1.2 installed

[parking sun]

OK, my machine has been running Ableton Live for 30 minutes with no libxpc log flooding. I achieved this happy state by running the celemony melodyne 2.1.2 uninstaller, then rebooting. Then OSX claimed Ableton Live was corrupt, so I re-installed it. THEN I ran it, and it's still running fine.

Now, of course, I have no Melodyne Editor; but then I can't imagine Celemony fixing the 2011 version of the software, Melodyne 2, when they want to sell us the 2016 version, Melodyne 4, so I assume it was going to break anyway soon.

Anyway, my machine now works without need for a complete rebuild; apart from polyphonic pitch editing.

Does this also work for others?

[laurentius]

I had Melodyne installed before and the craziest of behaviour in Ableton and a crazy log in "Console". I happened to reinstall my whole system last week and left Melodyne - don't use it any longer anyway. What can I say: Works nice and smooth!

[fishmonkey]

okay, uninstalled Melodyne Editor 2 this morning and have had Live running for a couple of hours in the background. no Console errors! so it seems that Melodyne is the culprit...

hmmm, i wonder how this affects using Studio One, which also has Melodyne support?

[Stromkraft]

Then OSX claimed Ableton Live was corrupt, so I re-installed it.

Did this re-installation entail extra packs and fresh preferences as well? I wonder to what extent a re-installation of Live might have affected this issue of yours.
I've done 2 re-installations in the past 3 years, much needed at both times, and it has been very effective for the issues that I had, usually involving instability.

[fishmonkey]

so i've had Live running all day, still no Console crap...

[parking sun]

Then OSX claimed Ableton Live was corrupt, so I re-installed it.

Did this re-installation entail extra packs and fresh preferences as well? I wonder to what extent a re-installation of Live might have affected this issue of yours.

No, nothing special - I just copied the Live 9.5 App from the installer image, and the app plus all the live packs etc remained authorized.
I rebuilt the machine completely a couple of times in the last 3 months, and those times I had to reauthorize. Plus, those times didn't fix the problem either, presumably because I reinstalled Melodyne...

[GrooveSlicer]

Hello All

For me too In el Capitan it seems it's celemony melodyne .... When delete all files problem finished.....

[jyanuary]

Has there been anyone whose libxpc.dylib flood has NOT been fixed by removing melodyne..?
I'm on ableton 9.6, removed melodyne and it still screams for help..
