Hello and welcome. I'm a jazz player and I have both Windows and Mac versions. The Mac version was just updated to version 2018 and it has MOST of the features of the Windows version. If there is something specific you need to know, we can answer. In addition, the piano roll which is one of the main differences is expected soon for the Mac version. The Windows version also comes with RealBand, a free DAW that integrates with BIAB. The Mac version does not have that, but you can drag tracks into Garageband.

The advice you will get here is to buy as much as you can, but the base program is the same no matter what version you buy. You can always add styles and RealTracks later. It's more expensive to add individual paks than to just get the UltraPak with them all.

+1 for Monk and Kenny Clarke
