Ana not working in Ableton Live 9 on Yosemite Macbook

Hey all and thanks in advance. I just downloaded Ana and am a recent convert to Ableton from Logic. Ana downloaded successfully, the license was installed and accepted, but I have no idea where/how to find ANA inside of Ableton. Don’t know if it is an Ableton thing a new OS X (Yosemite) thing or a “new user of Ableton” thing.

Go to prefrences / files folders and make sure audio units are enabled.
