Hey guys, I almost want to buy the TWD season 1 plus 400 days but I see the 400 days is not mac compatible, why? really not compatible? seriously? even Steam version is compatible! let me know ASAP before sales end!

I hadn't noticed that before, but it seems to be the case: I only have a Windows installer download option for the DLC. Weird.

Not unless you use a workaround to run the Windows version of the base game, no. (And, since I'm not a Mac user, I can't advise you on how to do that.) :(

is ok! luckily I haven't buy it, but I do hope I can buy them from GOG instead of Steam ,I don't want DRM and able to launch the game without Steam open!

after I had purchased the main game for Mac, "400 Days" appeared in the list of DL'ed episodes, after Episode 5, of course. I did not, however, actually make sure that I could actually play it because I could I only do that by having the game create choices for the previous five episodes. I suppose I could have done that, played a little bit and erased my "400 Days" save. anyway, it appeared that Mac users get "400 Days" for free. don't blame me if that doesn't actually work, though!
