The download is normal without any type of problem, the problem occurs when I extract the file, I run the program and a window appears with the message: "Discover my Body" is damaged and can not be opened. You should move them to the trash.
1. download the itch app for mac
2. login to it
3. if you see that discover my body is already in your library on the app, delete it
4. redownload the game and try to run it
Thanks, I already tested it and is working. Now I'm going to enjoy it! <3
