99.9% screens will crack while folding

My personal essentials:

Wipr - simple adblock for Safari (MacOS/iOS)

AlDente - useful if you’re keeping your Mac under charger for a longer time. MacOS has very similar feature build in but it may not work if you’re randomly plugging in and out your charger.

Rectangle - free tool for very quick windows management, snapping etc.

Keka - great software for compressing and decompressing .rar files and other compressed formats.

OnyX - great free software for performing overall maintenance in your system

AppCleaner - uninstall programs and delete leftover files

FlipClock - basic screen saver with a clock

Amphetamine - keeping your Mac awake, useful for longer tasks when doing them overnight etc.
