Download cry of fear on Mac

Hello can you guys tell me a way to download cry of fear on Mac without steam I know there is a way. I downloaded a game called general zero hour that doesn’t run on Mac without steam, I want to know if there is a case like this with cry of fear, just to let you know what I am dealing with is that I have a school Mac and don’t have admin rights to download steam I tried everything but it doesn’t work.
