itch.io

go into terminal on ur Mac and find the path you need to get into the game files

the command should look something like this (or at least does for me)

cd Downloads/Paper\ Lily\ Chapter\ 1\ v1/

(the initial stuff doesn't really matter, just as long as you get to the game folder)

Then, because Apple is a lil piece of garbage, ya gotta tell it that the game isn't malware, in this case just doing this command after the other should fix it I think

xattr -d com.apple.quarantine Paper\ Lily\ Chapter\ 1.app

if that don't work maybe try this one as well

chmod +x Paper\ Lily\ Chapter\ 1.app

if you downloaded the game directly into your downloads folder you can, in theory, literally just copy paste these lines into the terminal in order

This is basically all off memory and I'm just procrastinating homework by doing this but hopefully this helps ya, it's a great game!

Well, that sucks :( 

Maybe you should use Windows. Mac sucks, so you should just sell it or throw it out. Windows is better, so it would be better to get one if you didn't already.
