It appears that the $20 is for the "Mac Special Edition" which includes the Mac client, a month of game play, a Valkyrie costume set, a
teleport-to-your-mission power and an Apple chest logo (sorry, just kidding about the Apple logo.) Once you've applied it to an account--new or
existing--you have access to everything from any client.
According to Positron and Lighthouse, if you don't want to pay for the goodies, the Mac client will be a free download (like the Windows client) and if you
just want the goodies, they will be available as a booster pack (similar to Good vs. Evil pack) early next year.
