Sassoon Joiner fonts: known issues

TextEdit 1.7 (application included in Mac OS X Lion 10.7.3)

Fonts are not displayed in the Fonts dialog (via Format > Font > Show Fonts or Command T).

This happens when fonts are installed by double-clicking or dragging to Mac Users home volume:

In Font Book, either create a new 'Collection' Folder or add the fonts to an existing Collection.

Alternatively, install by dragging to Public violume:
Mac HD/Users/Library/Fonts.
