Diacritics not showing up

I have created my font with all of the diacritic marks and it looks great, but after I export it does not show up. I’m on a MAC BTW. I open my glyphs panel in Photoshop and don’t see them there and I don’t see them in Font Book. What have I missed?

Have you seen this: Eliminating Font Cache Problems | Glyphs ?

Thank you I will try that!
