I have downloaded this many times but keepremoving it after some time. Its a good app but only if you dont use headphones like i do. I cant hear anything whne i use my bluetooth headset. I contacted them many times without ever having a reply.
I agree with Loxer, Boom2 & Boom3D are pretty great and I have enjoyed versions them for years, but this is comparing a paid program to an open source program. The advantage of Boom3D (my current) over eqMac2 is that you can get a 3D Surround quality (not great for all music) as well as ambiance, night settings, changing the pitch settings as well as a spatial quality that a standard equalizer is not going to provide.
That said, this eqMac2 fills a gaping hole in the sound control for any MacOS and it would be great to not only download & install it but show some developer love by donating. :)
