There is a bug that many Mac users encounter when they travel between the two continents when taking a boat or a zeppelin: they get dropped in the fatigue zone and are usually forced to spirit resurrect, sometimes even dropped underneath a zone, stuck and need a game master's assistance to teleport them to the correct zone.
For example, at the time of writing this I had just taken the boat from Menetil Harbor, Wetlands to Theramore, Duskwallow Marsh, unfortunately I didn't make it to Theramore as I was dropped underneath Dire Maul where I was stuck needing to hearth and try again as a level 22 couldn't get through the zone. As it is the holiday season there were no game masters online to assist me. Upon wasting 20 more minutes getting to the boat and waiting, the same thing happened as I was dropped into Feralas, this time without a hearth.
My solution: In the early days of Vanilla the boat that would take players from Auburdine to Menethil Harbor didn't work, so Blizzard implemented two NPC's to teleport people from the two way points, one for each direction.

I think it would be helpful for Mac users if this was implemented for all boats and zeppelins. Even if we implemented a small monetary charge similar to a flight path to avoid people abusing a teleport? Would definitely love an easier method to take boats for a Mac user. This could encourage people to continue using the boats rather than teleporting. However there is definitely the problem that all higher levels with deeper pockets would just pay the fee every time, while lower level characters would be heavier affected each time they took the boat, although it would only really affect lower level Mac users as there is no need for PC players to worry about using the NPC.
Obviously this is merely a suggestion that could be improved by the staff or other players, let me know what you all think!
