Super interesting to see the improvement in Mac. Is this absolute growth (more users?) or is this related to a decline in Windows users? I switched from Windows to Mac some years ago, and I would never go back, so maybe it's partly your installed base switching.

The Mac includes GarageBand, which is a great free DAW. So maybe that helps get people interested.

One thing to consider... As a casual user of BIAB, I find the interface absolutely overwhelming. It feels like an archeological dig with 30 years of features piled on, going back to the DOS days. (I used BIAB a long time ago!) As a result, I have barely used the last 2 upgrades I bought and instead do all of my music production and songwriting in Logic Pro. (Which is more complex than GarageBand, but also enables you to hide the "advanced" features, though that's not a perfect solution.)

I would gladly buy a new easier Mac product from PG Music even if (or maybe because) it had fewer features. Perhaps you can expand your user base by appealing to new users with a less complicated product. (With native M1 support, of course!)

Best of luck
