This is a correction to how MakeMusic says to install the Dolet 6 plug-in for my Mac. I'm using Finale 2011 for Mac, with operating system 10.9.5.
The Finale 2011 plug-in folder is NOT in the application folder. To install the Music XML folder containing the Dolet 6.8 bundle, at the boot disk level, open Library, then Application Support, then MakeMusic, then Finale 2011, then Plug-ins, and finally copy the MusicXML folder into it.
(For Finale 2009 for Mac, the plug-ins folder IS in the application folder, at least for OS 10.95.)
