I'm trying to play along with iReal pro and the speakers on my MacBook Pro aren't really loud enough. I tried to get the sound to play through my Logitech UE Mobile Boombox, but it doesn't work. There's no problem with playing anything else via bluetooth, e.g., Pandora works fine. I tried a google search but I couldn't really find the answer. Is there a way to play iReal Pro through an external bluetooth speaker? Thank you.
