BananaBin is a playful MacOS application designed to help users manage disk space by reminding them to empty their bin. When the bin takes up a lot of disk space, BananaBin adds interactive flies to the bin icon, increasing in number until the bin is emptied. Users can configure the disk space threshold in the app by clicking on the tiny Banana icon. Currently in beta, BananaBin is free to try, making it a fun and engaging tool for keeping your Mac tidy and efficient.
