Audacity not working on Capitan 10.11

I get:
10/19/15 12:30:58.917 AM Audacity[8561]: WARNING: The Gestalt selector gestaltSystemVersion is returning 10.9.0 instead of 10.11.0. This is not a bug in Gestalt – it is a documented limitation. Use NSProcessInfo’s operatingSystemVersion property to get correct system version number.

It is much better to start a new topic rather than jump into someone else’s months old topic. In particular, El Capitan is no longer a beta, non-released operating system. I started a new topic for you.

Please make sure you are using Audacity 2.1.1 from Audacity ® | Download for Mac OS and that you installed it correctly as per Installation: Do NOT run Audacity from the DMG!!!!

Then tell us what the symptoms of the problem are. When you try to launch Audacity, what exactly happens? And do you have the released version of OS X 10.11? See Apple Menu > About This Mac.

I had the same problem, Audacity 2.1.1 quittting immediately upon startup (with a cryptic message in the syslog file) on El Capitan.

I tried Audacity 2.1.0, and it runs fine.

Have you tried the solution in Fix for Audacity 2.1.1 not launching In your case that might be all that is needed.

Audacity 2.1.2 when released will not have that specific problem.
