Because of software patents, Audacity cannot include MP3 encoding software or distribute such software from its own websites.
Instead, use the following instructions to download and install the free and recommended LAME third-party encoder to export MP3 files with Audacity. FFmpeg 2.2.2 Mac from the links below should be used with the latest version of Audacity.
Even so, mistakes do happen, and when one does you will get an error message on the screen.
When the cable is unplugged/loose, the i Phone looses connection with i Tunes.
Your Mac freezes; the screen turns grey and displays a large power on/off symbol, and it says in several languages “You need to restart your computer”.
This message is the impressive-sounding Kernel Panic.
You can also use the ‘fsck_hfs’ command if desired.
Unlike i Tunes error 3194 or error 4014, i Tunes Error 9 is not a very common error code.
