Posting it here so it will get more exposure as I know Mac deals are harder to come by.

For $1 Min you get Steam Keys and DRM Free builds of:
The Journey Down: Chapter 1
If you beat the average (currently $4.23) you also get:
Blades of Time
If you activate them on Steam games should work on both Mac and PC and they appear to have separate downloads for Mac and PC for the DRM Free builds and you get individual Steam keys. (see Detruire's post below).
