No, Cross does not have BT support. For the simple reason that this isn't something Cross has to.
Cross communicates with the soundcard driver. It doesn't know what happens further in the communication. Could be wired/wifi/BT/...
It must be something with your BT environment and/or your speaker that requires fixing/reinstalling.
Don't know to much of MAC, but may it be some other app occupies it for exclusive use?
Just in case you didn't do so yet... a reboot could fix it...
