Also, make sure that the Zoom is set as your audio interface in the Apple OS system priorities, wherever that is.

I have a Zoom G5 (big brother for Guitar of the B3 for bass) and we have a B3 at Church.

I do not have a Mac. However, in order to record on PC with my G5, I have to one of a couple of things:

Option A: Set the G5 as the recording interface, which I don't like to do, because then I have to connect the line outs to my monitors - which I have connected to my Focusrite Scarlett audio interface at present.

Option B: I set the L/R line outs from the G5 into a couple of L/R inputs on the Focusrite, and then just use the Focusrite as the interface - this is my preferred methodology.

Now, as to whether there's a record method in the Mac version, that I simply have no idea about. But if you want to trade info on the Zoom bass/guitar processors as interfaces, I do have experience with that on the PC platform. They are an incredible value.
