As a heads up I think you may have uploaded the wrong Mac download. It says Atonemnet-redacted-macos.zip instead of Encounter and when downloaded its a undertale fan game?
LOL WHAT
HOLD ON
I DONT EVEN KNOW WHAT THAT IS LOL, BUT I FIXED IT
okay i found the zip file on my computer but it doesnt even open, i genuinely have no idea how this ended up in my files
