Hey neighbor, another guy from
"The Pay State" here.
I drag and drop from BIAB to Logic, Cubase, and GB all the time, it works really well !
As much as I really hate to be one of those "read the manual" guys...

(sorry)
... if you search in the manual for "Drag and Drop" (it's on page 281 in the BIAB 2018 manual, I'm not sure which version you are on) they describe it in much better detail than I ever could.
I'm sure it has to be pretty similar to the way the Windows version works, but if there are any Mac specific quirks you will find them in the pdf.
A lot of times I will drag and drop the separate tracks directly to the desktop, then I can decide afterwards which DAW to use them in, I tend to bounce back and forth between Cubase for MIDI and Logic for audio (depending on the weather, and how I feel that day).

Hopefully my rambling is of some help to you, if you have any specific issues related to differences in the Mac version let me know and hopefully I can answer them.
