Hii~ I maybe a lil too late but hey better late than never huh? I only know how to do it on windows I don't know if it's the same with apple
anywho! go into files and click "Local disk C:" go into user then the file with your name and if you see the "Disk C: > User" n stuff click that and type in \Appdata then go to roaming and then RenPy you should see a file named here for sweet hearts go into it and delete everything in it
Worked for me I hope it works for you
