try right clicking on the game and press open and then when the can’t open notification pops up it should have an extra open button on it. press open and then you’ll have to put in a password and it should work. i hope this makes sense :)
I do this and it doesn't give a second option to place in my password. it just said it can't be open and it only gives my the option to press okay. I use a Mac book pro, does that have anything to do with it.
