There is a MAJOR BUG in Band in a Box for Mac,
which makes it not possible to listen on Bluetooth on your mac (by default).


The workaround solution is to go to Option-> Preferences-> Audio Settings-> Audio Device button, and select built in microphone on your Mac (or any other microphone just not Bluetooth).

Why didn't you fix this bug in the 2018 revision? (I reported this bug 1/2 a year ago).
It is will take a developer a couple of hours and make a lot of customers happy. Other products can deal with this, why can't Band in a box??
