For the past couple of years now there has been a pretty consistent 6 month development cycle between the Windows and Mac versions.
Each new Mac release brings the 2 versions closer and closer in feature parity.

Years ago there may have been a gap of a year (or even more) between releases for the 2 platforms.

Back in those days PG would release interim Mac updates, which did nothing more than to make the present Mac version recognize the newest Windows MIDI styles and such (this was in the pre-RealTracks days).
This was so you could purchase the newest Windows MIDI styles separately, before the latest Mac BIAB was released.

Since the advent of RealTracks things seemed to have changed a bit.
I can't remember any interim Mac releases that just added new Windows styles to the Mac version, any updates have been improvements and bug fixes.

It's just a guess on my part here, but that would lead me to believe that any new styles won't be recognized by the Mac version until there is an update.
There haven't been any Mac updates since the release of BIAB 2016 for Windows, so I would just wait.

Just my $.02 YMMV.
