@hanifanze, I agree with @SkrubWorm, I'd go and look for an alternative. Piriform doesn't care about Mac users CCleaner hardly ever gets an update (14 months ago) and are extremely slow at keeping up with macOS updates. And since the acquisition by Avast (presuming I'm allowed to mention other company names?!), the free Windows version is getting so bloated with unnecessary 'features', pop-ups and sneakily installing 3rd party software (Avast Anti Virus, coincidentally ), it's becoming unusable. It's definitely living up to its original name and what the first 'C' in CCleaner stands for! https://en.wikipedia.org/wiki/CCleaner
