Unfortunately the UI Mod you are trying to use is based on the LOY expansion( Legacy of Yakesha). EQ for Macintosh does not have that expansion (yet).

The first line states you MUST have LOY expansion.
Sorry for the delayed response. I dont read these forums daily. For additional help on EQ for Mac, you can always visit
