What good enhancements does it have? Not a rhetorical question, I am genuinely curious and have seen nothing mentioned.
I can understand; the bad interface stuff upstaged everything.
Off the top of my head:
• Spotlight is the big one, with a number of fixes, some reorganization, and powerful shortcuts stuff. (Unfortunately I was affected by a huge bug until 26.1 that disabled file search, and the "apps" view killed the much lovelier Launchpad, so "enhancement" is already debatable. But the new features are at least there.)
• iPhone integration brings Live Activities to the menu bar (pretty cool), and the call screening stuff from iOS is available from the Mac.
• Not really an enhancement, but Web apps at least use the compact window title bar and still honour the app's theme colour, which is a halfway-tolerable native look for Tahoe.
• Control Center gets the customizability and the dozens upon dozens of new controls that iOS had. You can add individual controls, or pages of controls, arbitrarily to the menu, including things like toggles for individual HomeKit-connected devices. Very convenient if you have them.
• Shortcuts has new intelligence-based actions, which have struck me as perhaps the first actually exciting manifestation of Apple Intelligence for regular users. (Not enough for me, but the new feature is at least there.)
• A bunch of new Background Sounds options for ambient noise. Great stuff.
• Options for light, dark, clear and tinted app icons. (The unpleasant specular edges are the one thing you can't customize, but even the "dark" option is welcome.)
• The fully transparent menu bar is probably nice for people who don't like the opaqueness and don't want to fully hide it.
• Folder icons are pretty nice with a new appearance and animations, and they can be easily customized with colours that match the existing tags, along with whatever emoji.
• Being a developer, there are also a lot of new or improved APIs suggesting to me that the people conceiving and implementing the actual "how it works" are still there.
• We have a native central Games app. You know, they're still trying. I suppose.
I'm sure there's more. For those immune to the interface, those are all potential plusses for certain people.
