According to Everymac.com, my iPad Pro 11" 2nd generation and my MacBook Air M1 16GB are about the same vintage ≈ 2020 release. The MacBook Air has a M1 chip, and does AI stuff, while the iPad Pro has A12 chip, and doesn't. I've never used such good computers in my life; they *are* the best.

iPadOS 26 is fine: it is easy to forget that it is different from iPadOS 18. While #Tahoe feels like my MacBook Air hit a brick wall.

With Reduce Motion & Reduce Transparency, comparable (same) apps perform slower on macOS than iPadOS:
- Everything on Safari: scrolling, window resizing
- The new chat backgrounds in Messages

And yet, 3rd party apps are OK. I have switched to the Waterfox browser on MacBook Air, and it is incredibly speedy. The DuckDuckGo browser also works fine. For now, both have windows with the "older" corner radii.

I grew up in the era where one company released one or 2 basic operating systems. I think that it is unprecedented that one company releases so many operating systems, and all in one day. AFAICT, the other Apple OSes are ok and little changed: watch, TV, HomePod, visionOS, iPad and iPhone/CarPlay (yes, I use all these).

I don't think this is a Liquid Glass thing: Liquid Glass is fine, and not that big of a deal. #macOS performance is bad this year: is it because of a lack of time? Or because it's Apple’s more complicated OS? Dunno. Have to see what #apple does.
