According to these reports the reason is that the "lsd" folder in /private/var/db/ is missing, or the Launch Services database is corrupted, or it is some El Capitan caching bug (some system file not being updated or deleted). Gale does not have a /private/var/db/lsd/ folder on his 10.10 or 10.12 systems, nor any "com.apple.lsdschemes.plist" files according to the find command run in a terminal on 10.12. Other users say the same.

GROUP: Launching Audacity * (Mac El Capitan) '''Audacity may not launch and a "Can't be opened" message will be displayed.''' Console log messages may refer to "Could not store lsd-identifiers file at /private/var/db/lsd/com.apple.lsdschemes.plist".

Right-click or CTRL-click over Audacity.app, choose "Show Package Contents", then in the "MacOS" folder, double-click the "Audacity" executable. This will launch a Terminal window and Audacity will also launch. Alternatively you can try resetting the LaunchServices database by running the following Terminal command then rebooting: {{codelist|sudo /System/Library/Frameworks/CoreServices.framework/Frameworks/LaunchServices.framework/Support/lsregister -kill -r -domain local -domain system -domain user ; killall Dock}}
