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!

Love the game, but devs, please just resign the Mac .app before you upload it. This takes all of 5 seconds.

codesign -s - -f --deep ./CoQ.app

Had this problem but was able to get it to work by switching to the admin account and holding  the control key and clicking  on the CoQ icon to open the menu and and then clicking ‘open’. 

FYI I just had the same problem and this worked for me, too. Thanks!

If this doesn’t work try: sudo xattr -c /Applications/CoQ.app  https://discussions.apple.com/thread/253714860 maybe the quarantine didn’t work for me because i still have an old version of the game going?
