For those who have a Mac system and are unable to open the game, here's one way I found useful from ChatGPT. In your Terminal, enter "xattr -cr "(fully copy and paste the thing in the quote, including the space) , then drag the After Hours.app into the space after it, which should look something like this: "xattr -cr /Users/xxx/Downloads/After\ Hours.app"(given by ChatGPT, thus not the same code you are going to have). Hit Enter, and you should be able to open up the App on your computer.
Note that you would have some bugs happening in your game after you open it up this way (such as wrong voice line, or unable to save(that I didn't save yet)). If you feel fine about it, just try it!
