While the Standard Edition is supposed to work with both Win and Mac the Special Edition is shown as Win-only. There's a Win and Mac package with just the Artbook for 4.99€. I can't imagine why the mp3 soundtrack shouldn't work on a Mac.

So my request is:

If I bought the Special Edition which seems to only differ from the standard by the Soundtrack. Would that seriously mean that I can't download/install the MacOS version of the game despite having paid extra? Is this a mistake or is there any understandable reason for excluding Mac-users from the soundtrack?

Thx for your efforts,
Homer

Edit: I just realized that there's also a 6.99€ pack for the Soundtrack alone. Also win-only ...

I haven't purchased this one yet so I can't say for sure but sometimes developers have a DLC installer that installs the soundtrack (or, maybe more commonly, is just a mistake and installs nothing). So that might be one way it got marked windows only if not a pure mistake. I haven't seen one that doesn't also have a direct download of the soundtrack as an "extra" so I suspect it would work fine for you (and you should be able to get a refund if it doesn't).

Refund is a surprisingly easy and obvious tip actually ...

That solves it for me, thank you! :D
