So recently I switched from using the sites latest version to steam download and I have no idea how to access my replay folder or textures folder to delete a floor texture I'm not using. How do I find those files on steam and on a mac?

~/Library/Application Support/Steam/SteamApps/common/Toribash
They should be there for steam version.
and for floor texture you're not using, maybe you should redownload your character.
