I am running a MAC OSMojave 10.14.2 and have just installed the latest audacity 2.3.0 update in accordance with recommendations. Now I can’t import the music from my MAC to edit for my radio show. I followed some recommended steps but it still insists Quicktime is not supported. This is now problematic as I cannot put a show together and I have deadlines to meet. ANY help would be greatly appreciated.
I presume that you are trying to import files that are in a format that Audacity does not natively support.
If you install FFmpeg for Audacity, then FFmpeg will handle most audio formats that are not supported natively by Audacity.
See here for how to install FFmpeg for Audacity: https://manual.audacityteam.org/man/installing_and_updating_audacity_on_mac_os_x.html#macff
