John Gruber @gruber makes a lot of really good points in this, & hopefully we’ll see a renaissance in user interface design at Apple with this change. This point really stood out for me, though:
“I am not a Liquid Glass hater. I actually think, on the whole, iOS 26 is a better and more usable UI than iOS 18. But MacOS 26 Tahoe is a mess, visually, and I’m not sure there’s a single thing about its UI that is better than MacOS 15 Sequoia.”
