nu — Cheese your Mac.

  • No SIP disablement
  • No admin password
  • No internet
  • Built entirely on Apple’s native frameworks
  • Easy key trigger

Window Manager

Also it can place the same window in a different space

I only use F + another key in this video (all of these are configurable)

E: Switch windows
A: Switch iTerm (terminal) windows only
Z: Switch Brave (browser) windows only
S: Show all windows
W: Focus on the next window
J, K, L, I: Move a window

D: Switch spaces
C: Show all spaces

Key Remapper

This OS-level key remapper lets you directly trigger all internal functions, features, and user macros

Simple key mapping

Hold F, press E, switching the windows

Per-app behavior

A + W ⇒ Page Up (default), Command + W when Brave is active

You no longer need to:

  • Use verbose hotkeys (eg Command + Option + 1)
  • Use modifier keys (eg Command, Control, fn, Shift)
  • Assign macros, layers, tap dances, combos per keyboard in QMK/ZMK/Vial etc

Unlike QMK, there is no concept of layers, rows, or columns

Each key is treated simply as itself, so A is A and B is B

Put simply, the same setup can be used no matter what keyboard you have

MacBook’s built-in keyboard, your weird smol board, or the keyboard at the office

Just plug it in and it works just the same

Text-driven Controller

This makes all of these searchable and controllable

  • Files
  • Apps
  • Browser tabs
  • Clipboard
  • UI element in a web page
  • Items in the menu bar
  • System settings/UIs

You can also ask AI in your favorite browser

From anywhere. No API key required

Voice Command

All features can be invoked via a custom phrase you configure

eg

  • Saying ‘next’ to move to the next space
  • Using the Apple’s native dictation feature to turn your speech into text

Even children, older adults, and individuals with physical disabilities can control a Mac easily using just their voice

It also has a joystick mode

Bonus features

  • Screen resolution switcher
  • Mouse scroll direction reverser
  • New scroller
  • Live wallpapers/videos
  • Trackpad haptic feedback controller

About the naming

It embodies the idea of solving the long-standing challenge.

Computer interaction.

Input/Output

nu

nu sounds the same as ‘new’

In Japanese, if you map its sound to a kanji, it becomes ‘入’

It means ‘input’

And when inverted, it forms the kanji ‘人’

Meaning: ‘human’
