Question about PreOrder Amnesia

[inside Stargaze]

Thanks for the answer but how is it with fhe Frictional Games Store? Will I bw abele to Download both, the Windows and the Mac Version with just one PreOrder? (Penumbra for example, I need to buy two times, one Windows and one Mac Version)

Sorry if the answer ist just in the linked Thread, but english isn`t my native language and I have sometimes Problems with understanding the whole sense of some Postings.
