For years now, Apple’s been judicious with its MacOS updates. Understandably so. Given the massive online outcry every time Facebook changes the placement of a button, it’s in UX designers’ best interest to keep changes gradual and subtle. These days, the overarching philosophy of operating system design seems to be more about guiding the user’s hand and making pronounced changes over time.

By the standard of annual consumer electronic upgrades that Apple has played a key role in perpetuating, updates to MacOS have, perhaps, been too subtle to foster the same sort of excitement. And honestly, that’s perfectly fine. If a laptop is a flashy new car, the operating system is the great steering wheel that doesn’t whiff out the window while you’re driving.
