Hi. A problem has occured and it´s the first time it happens. Audacity does not start at all. Info pops up and says it was shut down and that I can choose to report, restart or ignore. I have tried all alternatives. Same problem with both 2.1.1 and 2.1.3. I use OS 10.10.5 but have´nt changed or updated anything since last time I ran Audacity which was just a couple of weeks ago. Any suggestion what the problem could be?
You have to try everything in the FAQ. Think of what changes you made that might have affected this, such as adding more plugins or so on, even though you thought you had not made changes.
Can you also attach a screenshot of the error you see? Please see how to attach files to forum posts. That sounds like an exception error in Audacity which is usually due to lack of memory or incorrect memory being referenced, but I would not expect to see that on launch of Audacity.
OK then you could click “Report…”. You should see the report says that one of the threads crashed. Drag-select down from the top of the report to the end of the thread that crashed, copy, and paste here.
Use Go > Go to Folder in Finder to get there.
It might be an idea to delete that entire ~/Library/Application Support/audacity/ folder.
If that does not help, right-click or CONTROL-click over Audacity.app, click “Show Package Contents”, expand the “Contents” and “MacOS” folders then double-click the “Audacity” shell application. The Terminal will open and (normally) Audacity would launch. Does it? And if not, what messages are given in the Terminal?
