Put it on your desktop, open terminal and type "cd desktop", right click the mod and press "Show package contents, go to "Contents" folder then "MacOS" folder, in terminal type "chmod +x [your file executable]" instead of typing "[your file executable]" drag the file inside of the "MacOS" folder onto that, then from there it should act like a regular app and just go in security and privacy, press open then it should work.
