Audacity crashing mid-recording

Ever since I downloaded El Capitan from Yosemite (I got around to downloading El Cap in December), Audacity’s not been working the way it used to without a hitch. I can open the application, but when I start to record, after about five seconds or so, the colour wheel comes on, and either my whole computer freezes or the application just disappears. I’ve re-downloaded audacity a few times, which hasn’t helped.

I think El Cap is the problem, but perhaps it’s something else I’m doing. If El Cap IS the problem, what are my next steps? Un-installing it?



El Capitan is a problem…

There have been some security fixes to Core audio and there definitely is a bug in it somewhere. It doesn’t happen for everyone, so it is a complex bugger to find.

What interface are you using? Or are you using the built-in line-in or mic?

There are a number of fixes, starting with a pram and SMC reset…

Also, do you happen to have an Apple Fusion Drive in your Mac? These seem to give various problems with audio too.

Please tell us your version of Audacity (all three numbers, see the pink panel at the top of the page).

If you have Transport > Sound Activated Recording enabled in Audacity 2.1.1, this may crash.

In case El Capitan is not the problem, I suggest you try “2.1.2 RC3 (for testing)” near the top of


Roll back to Yosemite…
