Font Family Export

Hello, I am trying to export a font family, but not sure how to do it properly. I have a set ( bold, regular and thin. ) So I want them to be in one branch on my font book ( I am working on Mac). Right now when I installed them it is all separate fonts but not a font family.

This could also be a font cache problem. Read this please:

Better use the Adobe Fonts folder:

Fonts that have the same family name should be grouped in the menu. Windows and Office font menus can only group the four default styles (regular, italic, bold, bold italic).
