There are a lot of things that are behind in the Mac version, I suppose it all takes time.
Can you just add a midi click track to one of the slots or an audio loop, just for now to get you out of the predicament ?

You can easily make up a click track as a UserTrack just have "Drums" in the name so BB don't transpose it, then just add the UserTrack to a slot.
If you can't do this let me know and I will make one up.
