After latest Mac patch, SC2 starts > Versus > (Any Choice) > Game is starting > popup screen says “Attempting to Reconnect – SURRENDER” > Game stays stuck there or clicking surrender button disappears the popup but game stays stuck and must be Force Quit.
Going through all the steps for connection/disconnection issues has no effect. Scan and repair has no effect. Deleting Battle dot net folder has no effect. I have no Internet problems and all other programs function. It’s a patch bug. OS High Sierra with all updates.
