Agreed. Maybe I'm in the minority, but in the screenshot comparisons I greatly preferred the AI products. The Mac OS stuff seems bloated.

I had the same reaction as well, the macOS designs looked busy and cluttered. I was surprised that AI companies had landed on something more refined.

If nothing else: why is the left sidebar in macOS Liquid Glass on a raised panel? There's no need for it, and that's a whole round-rect of unnecessary visual clutter that can be removed.
