Makemusic or Eminor or Finale no longer has a free Printmusic type of software for Macintosh. Drag! Now all the scores I've created to help people enjoy great songs like Ave Maria, Schubert's Serenade, Mozart's.. can't be printed in various keys for free..

I can save my files in .xml and then if I find the right tool I can tell people use that tool with my .xml files..

What free music XML tool should I suggest? Any suggestions where I can find a comparison or assessment? Thanks very much in advance!
