MacOS aesthetically peaked with Leopard in '09, but speaking frankly the OS has felt abandoned to me since around 10.2, with so many basic interaction issues with window management and the dock just never getting fixed properly and a long list of half-assed bandaids and abandoned experiments over the years.

There is no true passion in MacOS, and the marketing has come face to face with reality in 2025. It's the neglected step-child of a company distracted by other things.

There's been some impressive engineering done by lower-level folks under the hood of it all, though.
