Macbook pro, 2017 macOS Sierra Xquartz installer downloaded from www.xquartz.org Installation proceeds, but clicking on icon does not bring up a window and app must be force-quit. No other option. Cannot use with x2go client, which is one of the end goals.
Update to a newer beta. I believe it was fixed in beta 6. If you have issues with macOS, please file a radar.
