Bananas.
The game unfortunately doesn't run on a mac, but I believe there are emulators available that allow you to play windows games on a mac. If you don't want to look for/install those, there are a couple of playthroughs people have made of an earlier version of the game!
There isn't actually an item to collect in the laundry room; there's just Chad waiting in there to jump out at you.
If using the hints option in the menu doesn't work for you, I can tell you that the three passcodes are found in: the dining room, the second bedroom, and the attic. Check all the closets and doors in the hallway and downstairs, even if you've clicked on them before! :)
Hey, this seems like it'll be really cool! :D I can't wait to check it out when it's finished!
