With a particular score when I open it I get a message that Bravura Text Bold is not installed on my computer. I checked in Font Book and I see that I have Bravura and Bravura Text installed. Is this an issue?
There is no bold weight of Bravura Text, so the problem will be that one of your font or paragraph styles (the dialog will tell you which kind it is) is set to use the bold weight of Bravura Text. Go through the lists of font styles and paragraph styles in their dialogs to find out which font style needs fixing up.
Ok that explains it. Thank you.
Found it. I had selected it in the Chord Symbol Font
