Mole

“Also worth a look: Mole (mole.fit). It's a native Mac utility that rolls together the jobs you'd otherwise need four separate apps for — clearing caches with a review step before anything goes - uninstalling apps properly instead of leaving debris scattered around - a treemap of what's actually eating your disk - live CPU, memory and battery readings in the menu bar Nineteen dollars once, covers two Macs, no subscription — which after a decade of everything on the Mac quietly turning into a monthly fee feels almost quaint. It started life as a command-line tool and that version is still free and open source if you'd rather not pay at all.”
