So I have a MacBook Air, and I downloaded the game from YandereDev's blog. When it fully downloads, I open it, but it says, "This can not be opened because the file may be damaged." Why? Do I have to download it off of Google Chrome instead or Safari? And what do we open the file with? Adobe Reader or whatever?
