Issue – cant open .m4a files
OS – macOS High-Sierra version 10.13.6
Audacity – Mac version 2.3.0 (https://www.fosshub.com/Audacity.html)
FFMPeg – 2.2.2 (https://lame.buanzo.org/#lameosxdl)
Error message – ‘This version of Audacity was not built with Quicktime support’ (maybe slightly misquoted)
I have not tried any other quicktime extension such as .aac
My older version (2.0.x? maybe) version of Audacity, copied from an older hard drive worked but frequently (not always) terminated when I opened a .m4a file. When Audacity did not terminate, all functions worked without issue, however the frequently failures were painful.
To remedy that problem I downloaded the current 2.3.0 but I immediately receive a message upon import (sorry, doing this from memory) ‘This version of Audacity was not built with Quicktime support’. I’ve been using Audacity for years and dont recall having to add FFmpeg library and the old version worked without it on a fresh OS installation. I did the install anyway, after reading the help file and the forums. Now, Audacity does not complain when I attempt to import, however the imported file is not correct. I removed the audacity.cfg file from ~/Library/Application Support/audacity/, however this does not resolve the issue.
Since installing FFMPeg 2.2.2, the old version of Audacity is no longer functional.
Does anyone have a solution on how to get Quicktime support working?
