Ableton gets slooooooooooooow

Post by laurentius » Tue Oct 13, 2015 6:45 pm

Hi there,

I am using a mbp 2014 with enough ssd space left and full ram. Since a couple of days my Ableton causes serious trouble. As soon as the macbook heatens up a little (after a couple hours) Ableton gets so slow that it's unusable, browsing gets impossible, clicks delays for several seconds. It affects the whole system, I get kernel error overload and unrealistic cpu usage values.
Even weirder is that this happens especially when the power adapter is connected. When I tear it out it works a bit better. The temperatures are not soooo hot (according to istat menus it is around 70 celsius) so I don't understand why the system is out of control. And it's just with Ableton. I can run Photoshop and Final Cut Pro at the same time and none of this phenomenon appears...

In the mac console software I get this message many many times per second when Ableton is on:

Live[661]: assertion failed: 14F27: libxpc.dylib + 33325 [5C829202-962E-3744-8B50-00D38CC88E84]: 0x13

Any idea what's wrong here?

Thanks for helping out,
L.

I piggybacked my answer to this onto this other thread, because it seemed to be better documented: viewtopic.php?f=1&t=217381&p=1680977#p1680977

I had this issue for 6 - 9 months. With the same line in console as you. 4000 entries every six seconds. Ableton's technical support checked my sessions and log files. They couldn't find out why this happened. Even formatting the hard drive and reinstalling it didn't help since I used the migration assistant on Mac to copy my user data to the newly installed computer.

In the end I formatted the hard disk again and reinstalled everything without using any old data for my user account. Since then it works. It seems to me that it is a software issue. Maybe something in your Mac's user account got corrupted. I'll have to tell Ableton that this solved my problem. Good that you remind me with your question.
