defaults write command, which writes preference values directly to macOS’s built-in preferences system. Each setting lives in its module’s install.sh file — to change a value, you edit the relevant file and re-run provisioning. You don’t need to touch System Settings manually.
Keyboard
keyboard/install.sh sets how quickly keys repeat when held down.
keyboard/install.sh
To slow down key repeat, increase either value. To make your keyboard feel more responsive for navigation, decrease them. The minimum macOS allows via System Settings is
KeyRepeat 2 and InitialKeyRepeat 15, but you can set lower values by editing these files directly.
Mouse
mouse/install.sh controls pointer tracking speed for a connected mouse.
mouse/install.sh
com.apple.mouse.scaling value is a float where higher numbers move the cursor faster across the screen. A value of 3 is noticeably faster than the macOS default. Decrease it (for example, to 1.5) for a slower, more precise feel, or increase it beyond 3 for a larger display or high-DPI setup.
Trackpad
trackpad/install.sh sets the trackpad tracking speed and enables tap to click.
trackpad/install.sh
To disable tap to click, set
Clicking to false. To adjust trackpad sensitivity, change the float value — 1.0 is a slower, more controlled feel.
Dock
dock/install.sh configures Dock behavior and removes several default Apple apps from the Dock.
dock/install.sh
The file also removes a set of Apple default apps from the Dock (Safari, Messages, Maps, and others) using
dockutil. To keep any of those apps in your Dock, remove the relevant entry from the default_dock_applications_to_remove array in dock/install.sh.
Security and privacy
security-and-privacy/install.sh configures the screensaver password lock.
security-and-privacy/install.sh
For example, to require the password only after 5 seconds instead of immediately:
Applying your changes
1
Open the relevant install.sh
Navigate to the module directory for the setting you want to change — for example,
keyboard/install.sh for key repeat settings.2
Edit the defaults write value
Change the integer or float value in the relevant
defaults write line. Keep the key name and type flag (-int, -float, -boolean, -bool) unchanged.3
Apply the change
Run the full provisioner to apply all settings:Or run just the module you changed for a faster iteration loop:
