Now, I cannot take credit for anything written about the solution, this was done by a user who wishes to remain anonymous and I respect that. Thank you to those involved, you know who you are and well done.
What I cannot understand is why Telltale cannot offer a different delivery method being that the solution can be easily performed.
It is all in the files being delivered for Episode 3. These go in the following locations
/Users/"your user name"/Library/Application Support/Telltale Games/TheWalkingDead/SyncFs/Data/WalkingDead103
/Users/"Your user name"/Library/Application Support/Telltale Games/TheWalkingDead/SyncFs/Meta
If Telltale would be kind enough to offer an alternate direct download and users can copy those necessary files accross you would be playing the game now.
The download is only just under size of a CD, not large by todays standards.
How about it TT, can you please let us have these files so MAC users can play this game.
(Before you ask, no I don't have a method of delivering the files you to directly, I'm hoping Telltale can help us with this)
