Ask HN: Lesser known features of macOS/iPadOS/iOS/etc. 27

4•lucasoshiro•53m ago
Hi there!

I've just upgraded my Mac and iPad OSes to 27 and found some interesting features that I haven't seen listed elsewhere:

- Screen mirroring to iPad now accepts touchscreen inputs

- iPad menu bar can now be always turned on

- The sidebars aren't floating, just like before Tahoe

- Decreased window border radius

- Increased resize window area
