So I'm not sure what I'm doing wrong as I've tried everything from completely wiping and reinstalling everything on my MacBook Pro 2018, I've ensured port forwarding has been done correctly, I've tweaked and even turned off all security and firewalls temporarily to see if they were the problem but so far nothing is working. The game downloads and goes through updating the client at least twice then on the third install and relaunch it tries to load then stop at about 2/3 of the way through and gives me this error. Patch update failed (talks about checking stuff on windows even though this is being run on Mac) then these codes: [11005] [20815] [20866] [19900] [32]. If anyone has a clue of what to do please help because I'm getting really frustrated. Everything else seems to work fine with other games I play.
