Howard at Eclectic Light has a post looking at the visual design mess that is macOS 26. I'm not using my Mac these days and I didn't install 26 so I have no first hand experience. He's got quite a list. The 60+ comments offer even more to the list and discussion, none of it is positive.

Timely that I just published a post about the high quality of the visual design of the Cinnamon Desktop on #Mint. I picked a good time to switch to #GNU #Linux.
