I cannot save to MP3 either on the Mac version. This software is ridiculous- not only do the advertised features only come with the Windows version; they do not even acknowledge that the Mac version is crippled. I will gladly pay to "upgrade" my software to the full version if MP3 output is enabled, but there is not even a clear guide as to what additional capabilities are enabled on the Mac version. Perhaps that incompetent, condescending admin will finally acknowledge that there is an issue with the Mac version and post a solution besides "simply go to save as... blah, blah, blah..." Oh yeah, he did say somewhere on here that features are being added to the Mac version, but failed to say what is going to be added, when it will be added, and what, exactly is missing from the Mac "free" version and Master Edition. Please just give a straight answer instead of a sarcastic, obtuse retort.
