If you’ve got antivirus, ALWAYS exempt the folder from the scanner.
If that doesn’t fix it or apply, go into the game folder with the game closed, find the EAC folder, and run the setup in there as admin (Right click, run as admin) and in there ‘repair service’, and try again.
the only thing that Gaijin says when i try to resolve this problem
“The game client has been launched without enabled EAC, in a session where EAC is required.”
Hello there.
I was just about to post a new article about the same exact problem you have here.
I play also on macOS.
When you start the game do you also have a strange message about ‘Firewall protection’??
Glad to see its not only my problem.
