adding on to this because it just worked for me, rather than typing in "TheFalseSun" just drag the game application file to terminal box and then press enter. It wont work if you type it, so make sure you drag the file into the terminal box!!!
I have one more trick that works for me when it comes to playing a game developed with windows on a mac computer. This should help with by passing the mac security system (access denied screen you see), so you can play.
So do these steps in order
- Open terminal app
- type chmod +x (make sure there is a space after the x)
- drag the game (the false sun) application file (.app) into the terminal window then press Enter
- then type xattr -dr com.apple.quarantine, then space and drag the game file to the terminal again and press enter (make sure to space after xattr)
- launch the game by right clicking the app and then selecting open
hopefully this works for you!! if not, maybe the developer can help with the problem, or you can find another way. make sure to type everything the way I did and include those spaces because they are important. If you have anymore questions I can try to help more! :)
