Several other posts have mentioned this......

There's an app or a program that lets you (dual) boot and switch to WINDOWS on a MAC.

The simple solution as I see it is to buy the Windows version of BB which gives you RB as well and of course the real tracks.... install the program on the MAC that lets you run windows, install BB on the Mac, use an external USB interface, and you should be good to go.

I'd do that rather than complain that PG isn't catering to less than 10% of the market, if I had a Mac.

You can make excuses or you can make progress but not both.

The magic you are looking for is in the work you are avoiding.
