Hi,
I created a project with Dorico Pro, using the MTF Cadence font.
When opening the same file in Dorico SE, I’m asked to replace the font. I enter Bravura, but then the score shows scrambled graphics, instead of music.
Not a problem, because I can install the missing font. Just something strange.

You should restart Dorico. This sounds like a Macintosh problem. Or better yet, as you stated, reinstall the font and keep it installed.
I don’t think it is a matter of font cache, since Bravura is correctly shown when the score is created in Bravura. It’s the replacement that is causing issues.
It’s not a matter of reinstalling the missing font, since it is not installed at all!

Don’t do anything when you get that dialog box. Just click through.
