Please remember to always test current FFmpeg git head 
before reporting issues here: It is safe to say that 
releases are not supported for osx.

The combination of these two messages usually indicates 
one or more forgotten characters on your command line.
The command line you posted works fine here, perhaps 
you have an invisible character somewhere?
Try to remove everything between -map "[acat]" and the 
output file name from your command line.

Please understand that this makes no sense in emails 
sent to a public mailing list.
