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?
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.
