Yasu (short for 'Yet another system utility') for Mac is a drop-dead simple macOS utility application that allows users to easily clean and maintain many different areas of their Mac system.
Yasu was intentionally designed to be easy to use. It's the type of application you can give your technology-challenged Mac-using parents to keep their system running smoothly. One window, with a handful of checkboxes and one button to make it go (and a password if it's needed for some options).
That's all there is to it.
Try it yourself to see how easy it is to use.
