MacOS doesn't allow unverified programs without an apple license to run directly and unfortunately it's too expensive for us to buy one right now, so, on MacOS, to be able to run the game, you must insert the codes that can be found on the Tutorial page right on the first one "Setting Up". The codes can also be found inside the MacOS folder when downloading the game ever since last month, to make the copy and paste into the terminal easier
As for your issue, you said you were trying to install the game on Windows 11, in theory, you should be able to install the game with no problems, as 98% of the players are using a Windows system to connect. If you're having troubles, it's either one very specific antivirus preventing you from downloading the game - not because it has a virus, but because it's from an unknown source doesn't want to allow it, or windows 11 itself, but with windows you should be able to proceed when the "Windows SmartScreen" appears. Either way, if you follow the tutorial you should be in the clear on both the MacOS and the Windows version!
