I have the Macbook Pro 2019, I already tried the search bar and found nothing. Also, I searched in all the folders after the "show package content" (of the itch app) and didn't find anything. Thanks for the response !
Oh, if you used the itch app that might change how things go, since the file is part of the app and not totally separate. Do you think you could try downloading the base game straight from its page rather than through the Itch app?
