No possibility to select faction and continue leveling with pandaren chars

First of all my apologies if I am duplicating a post but I was not able to find something exactly as it happened to me. I am a macOS user and use the MoP Windows client (as there is no client for macOS yet) and launch it via wine. Currently, I can play several chars with no problem except Pandaren. As I could read in the forum, the Pandaren starting zone looks bugger for a majority of users. Well, I'm not an exception and I am stuck with the quest "Still Good" (which I see it's bugged and already reported). My question is: could I select a faction somehow and being teleported to the main faction city and continue levelling from there? I really would like to level a Pandaren (also my girlfriend is able to play but only with Pandaren).

Many thanks in advanced.

The quest you are reporting works fine, the ones that do not do have workarounds
