When you say you have a “PowerBook”, is that actually an Intel machine?
The problem we have in 2.1.0 where files don’t import relates to the QuickTime importer, which imports MPEG-4 audio, not WMA. See Audacity 2.1.0: FFmpeg required for MP4/M4A/MOV/ALAC import.
FFmpeg should automatically take WMA files but as you can see from the log, there is a codec error 15027, so QuickTime then tries to take the file, but fails because it is not intended to take WMA files. Even if it was a WMA file inside an MP4 container, I doubt QuickTime would import it.
Did you obtain FFmpeg from http://manual.audacityteam.org/o/man/faq_installation_and_plug_ins.html#macff?
Codec 15027 suggests that the file is WMA lossless according to this reference. According to the FFmpeg documentation ( http://ffmpeg.org/general.html#Audio-Codecs) WMA lossless decoding is supported by FFmpeg 2.2.2, but I think that support may only be for 16-bit files, not 24-bit WMA lossless.
Are you saying Audacity 2.0.5 can import that WMA file? That would surprise me because 2.0.5 will not accept FFmpeg 2.2.2. It will expect FFmpeg 0.6.2 and I don’t recall that FFmpeg 0.6.2 would decode WMA lossless.
Have you examined the file in MediaInfo? That may give you more information about the file.
Yes please post a link to the file and I will have a look at it, but it could be a problem with FFmpeg 2.2.2 and not Audacity.
