I am a Mac user and I've downloaded eqmac because I like having a system eq.The free version still allows to save multiple custom settings with only a 10bands eq. The pro version allows to access a parametric eq, which I think could be the way to go. Only, I find eqmac very poorly reacting; often when I want to play something it may take several mute seconds before hearing the sound, and sometimes it freezes. Wondering if this occurs only with the free version or it is a buggy behavior no matter what. Has anybody experience to share? Or, could you indicate any other system eq which allows parametric eq in order to choose each frequency and Q? Thanks
