FORTNITE ON MAC NOT LAUNCHING SINCE NEW 4.4 UPDATE
After installing the new update, I tried to launch and nothing happed, it said it was running and the fortnite icon appeared in my dock, but there were no windows. I force quit and tried again. This time this screen appeared (see photo) and nothing happened. I tried the same, force quitting and relaunching, the same two thing happening. I uninstalled, reinstalled. Still the same. I have tried restarting/shutting down my Mac, still won't launch. The loading screen takes about 2 minutes to appear and then nothing happens afterwards. FortniteClient-Mac-Shipping appears in the force quit menu like it would if it was running properly.
