Step number 4 but now connected to the internet to see if there was an additional download of any sort that I had been missing (such as a patch that I was unaware of).Present inside there is this folder that I assume is the 400 Days episode: WalkingDead106. Right-clicked the TWD app with the installed DLC and checked there was a new episode present in: /Applications/TheWalkingDead.app/Contents/Resources/Pack.A combination of re-download of the DLC and deletion of the aforementioned prefs and plists.Re-downloaded the 400 Days DLC, and re-installed it.Deleted the game (garbage bin, then empty bin).Deleted all previous game preferences and plists, such as:, , Telltale Games folder from my 'Library/Application Support' folder.Troubleshooting Attempts: (all failed so far) Nowhere in the game there is the option to choose to play 400 Days. I applied the 400 Days DLC upgrade using the downloaded installer. I downloaded the game installer as per the instructions on the store of purchse, which are very straightforward. The DLC game has been downloaded and installed successfully, but when The Walking Dead is launched, there is no option to choose 400 Days, only the previous 5 episodes. I sent them a post similar to this but they have yet to answer, so I decided to come directly here and see if I fare better finding a solution for my troubles (that I believe I share with a couple of posts for the PC I've seen). I purchased 400 Days for my Mac about 10 days ago from the ineffably ineffectual MacGame Store.
