I've updated my MacBook to macOS Sierra, and it's rather underwhelming and half-hearted IMHO. And yes, dear eagle-eyed reader, Apple capitalizes the Mac in MacBook but not the Mac in macOS - what a confusing naming (lack-of-)convention. Still, macOS is a better name than OS X (can you say OS 10 10.X instead?)
I've stumbled on another "feature" that iOS 10 has mangled - Spotlight Suggestions in Look up. What does this double speak even mean? Worse, I can't even get rid of "Look Up" and revert my beloved "Define".
The Magnifier seems like it'd be useful. Here's how to setup the Home button Triple-click with multiple Accessibility Shortcuts and to avoid physically triple-clicking the Home button with the AssistiveTouch floating Home button.
