OTF Font not installing on Mac

Good day all,

Iv'e been trying to install a font, "Maria Rose Regular" to my Mac. Font says it's free for personal use, but everytime I click install font, the install proc comes up as if it's installing, then vanishes and still there's no font. Tried restarting, redownloading, etc. and nothing works.

Does Anyone else have this issue and is there a fix for it?

Thanks in advance.
