I'm not quite sure what to make of Liquid Glass, I developed an allergy of sorts to the term while listening to the keynote. Any 'relevant' new features for power users / cmd line geeks that you know of?

https://github.com/apple/container is supported from macOS 26

Apple Notes now supports Markdown import and export.

Spotlight now supports actions, so you can do things directly from Spotlight (kind of like Quicksilver back in the day, or Raycast more currently). Your custom made Shortcuts can also be triggered. It’s also context aware, so you can do things for the app/document you’re in.

Spotlight also integrates clipboard history.

The Terminal gets Powerline glyphs, new themes, and new fonts.

The full list of changes is here:

The changes to Spotlight are fairly power-user focused. There's a lot of enhancements to make it quicker to set up shortcuts within it, and they've added a clipboard manager feature to it.

This summary looks acceptable: https://www.computerworld.com/article/4041433/spotlight-is-m...

Not a direct response to your question but (I guess like you) I often find with these releases that the changes I actually care about aren’t flashy enough to even warrant a mention in the presentations or on the main web page.

There seems to be some expansion of screen time, finally, but I haven’t been able to figure out what it is yet based on the only *os 26 update I’ve done so far is the public beta on a single Apple TV.

I think we'll have to wait for benchmarks to see if this is a leopard or a snow leopard
