Mac people, I "updated" the "MacOS" version of TFMG using the following method copied from my post to that thread.
I tried the same method for WVM to "update" the MacOS version day1-3 to day 1-4, it worked on this game too...
basically trying to copy everything that might have been added since the last version, leaving out the things that are specific to Windows and Linux or seemed to stay the same from the last version.
To whom it may concern... I run on a Mac. So I downloaded the PC version Ep8 and copied the relevant folders into the Mac Ep6 version (overwriting the old ones). I was able to play though to the end of episode 8 without issues... I used my Episode 6 save too! Good luck Mac guys!
(gotta open the package if you don't know what I mean right click on the app)
Copy the lib/linux-x86_64/eggs folder into the Contents/MacOS/lib/darwin-x86_64 folder (might not be needed i don't know)
Copy the game folder and the renpy folder into the Contents/Resources/autorun folder
Copy ALL the contents of the pythonlib2.7 folder into the Contents/MacOS/lib/darwin-x86_64/Lib folder
Copy TFMG.py and TFMG.sh into the Contents/Resources/autorun folder
Again, I am not sure ALL of these need to be copied, but this worked for me!
Good Luck!
