Since the update to Mac OS X Sierra, when I open the launcher, it just gets stuck on "Installing Pre-reqs" with the window below that being completely empty. I have tried re-starting both the launcher and the operating system. Nothing. I reinstalled the game, which took an incredibly long time. The launcher worked right the first time it came up on its own after the reinstall, and then went to this bad behavior. I have messed with options, turning on "ask before installing updates," and it worked once, and then stopped working. Sometimes I will change the setting seemingly randomly, and the launcher comes back to life, but only once. I'm at my wits end, as I cannot play the game on this computer now. Is there something I can put in the proxy settings to get the machine to connect properly to the server? Please help.
