Doing Get Info in Font Book.app will tell you when this is an issue. Delete the old font and reinstall the new. I had to do this when installing Finale 2014. Some of my Finale fonts had 1995 build dates on them so I went ahead and removed every Finale font manually in Font Book.app. Search the Finale download library for updates, documentation, free trial versions and more.

The Mac version is MAESTRO_HFa.The Windows version is MAESTRO_HF.This {Horizontally Flipped Maestro} font was done by Finale user Mark Wibrow.

To “play it safe” I would consult MakeMusic before using the flipped font.
