I don't own Mac but apparently a recent update blocks all unsigned programs from running. I think you can Google a fix, but as I don't own a Mac I can't help you, I'm sorry.
It's ok, I understand. Btw I already fixed the problem after searching on the internet. I'll send you the link to my gameplay when I finished. But, if you'd like, please subscribe to me on YT: https://www.youtube.com/channel/UC94utkBG-YqZW5EKdV8uYlQ?view_as=subscriber
P.S (just in case): On mac, you need to type a command "chmod +x" and then the file that open the app + I want to be friends.
P.P.S: I also try doing games
I was just about to type a lengthy comment about how frustrating it is when someone who searches online for a fix, finds one and then goes: "nvm, found a fix" without stating in the thread what the fix was, but then I saw that you had stated it in the post script and I was relied of the burden of having to type a lengthy, rambling, comment.
Oh wait...
