Under Yosemite 10.10.5 with Boom 2 trial installed, activated and all seem to be ok.. configuration, menubar shortcut aso.. fine. BUT nothing is happening when I change profil between the 5 five default choices (fidelity, pitch..), nothing happen when I try to change volume aso..! I can do what I want, Boom 2 seems to be a "dummy" software. Sound coming out from iMac speakers remain unchanged, absolutely unchanged. What a pity.
