Font Garamond trouble

So it seems everyone is recommending this font to me for printed text. Unfortunately I don’t have it in my version of mac scrivener (2.6, most recent) and I can’t figure out why. This is a major headache, and I’ve tried to download it but I guess I’m getting bad links. Any help would be appreciated.
