There's an issue with the patch on Mac with missing pictures - I assume that's it about pictures of the previous chapter because it happens with "memories" of the MC. It's not dramatic. Another thing is that it seems that it is best you play a little and make a save with the unpatched Chapter4, and then patch it or you get the missing picture issue from the start and it looks like the game doesn't work properly. Maybe it would be better to introduce a working, already patched version? I know that issues with previous saves are not uncommon in Renpy - Ah yes, and I have to run the game from the renpy launcher because I get a "can't be opened" (the resolute one, not the usual "needs appoval because it's not apple"one) after patching.
Hey there. I'm so sorry you're having issues. Unfortunately, Itch has a 4GB file size limit so I had no choice but to chop up the update and make it into a patch, and what's worse is that I have no way of testing the MAC files.
Thanks for bringing this to my attention and I'll try to find a way to fix the problem as soon as I can.
