I'm gonna play the game but I'm scared about the final act, does like.. Monika read my contact name or something? I'm nervous (Macbook user)

Pretty sure the game just scans your admin name on your macintosh. Nothing else, just your name. If you put your name as something like "Ultimateconundrum" or any other username you have for your admin account name, Monika will just say that name. Monika said my real name for me because I put my real name on my administrator account but Monika didnt say one of my friends real name because they put something else on it.

On Windows it reads the user file :D

Cuz the game runs from that user file (C:\Users\[username]\[wherever your game is])
