MacOS 10.15 (Catalina) introduces additional restrictions on running non-Apple software. These restrictions prevent Audacity from functioning correctly, and may conflict with Audacity’s open source license (yet to be confirmed).
If you are currently using Audacity on an older version of macOS and wish to continue using Audacity, we recommend that you don’t update to Catalina yet.
Although Catalina is not officially supported, there’s a workaround that has been reported to work for some (but not all) user with Catalina and Audacity 2.3.2:
- Go to Applications > Utilities
- Launch Terminal.app
- in the Terminal dialog type the following command following command:
open /Applications/Audacity.app/Contents/MacOS/Audacity(this assume that Audacity is stored in your Applications folder. If it is somewhere else, you will need to change the path in the above command.)
- Confirm the request for microphone permissions when requested.
For additional information about this workaround, see this post on the Audacity forum: https://forum.audacityteam.org/viewtopic.php?f=47&t=107162&p=378694
This advice will be updated when more information becomes available.
