Hello fellow Mac users.  I know several of us have been having issues with MacOS not allowing us to open the game, but after some digging around online, I found a solution. Rather than deleting the app and using bootcamp to play instead, I found that there is a simple fix using the Terminal. Open terminal and input the following: "sudo xattr -rd com.apple.quarantine /Applications/CoQ.app", then press enter. The terminal will prompt you to enter your password. After entering your user password, the app will be able to launch as normal! Hope this helps :)

THANK YOU! That saved me from feeling total dread for paying $20 for something I can't use quite yet.

Hey there!  I had the same problem and tried your solution.  The Terminal gave me a "xattr: No such file: /Applications/CoQ.app".  I then realized I had to make sure the game file was in the Applications folder.  Once I did that the game worked!  Thank you so much for that work around!

thanks, problem persists, solution still works.

Thanks!
