 My configuration. Minimalist, but helps save a few thousand keystrokes a day. I use macOS, so I can only guarantee they'll work on a Mac, but I use some of these dotfiles on various linux servers, and they seem to be pretty flexible.
 
+## macOS settings
 
+Run `.osx` to apply macOS defaults:
+
+```sh
+./.osx
+```
+
+Use `--no-restart` while iterating:
+
+```sh
+./.osx --no-restart
+```
+
+The script configures:
+
+- Bottom-right trackpad corner as secondary click.
+- Screenshot output to `~/Downloads`.
+- Screenshot keyboard shortcuts disabled.
+- Spotlight and Show Apps keyboard shortcuts disabled.
+- Dock recent apps disabled.
+- Dock hot corners, Finder defaults, Safari developer settings, and other UI preferences.
+
+Some settings are cached by macOS services. If System Settings still shows stale shortcut checkbox state after running the script, log out and back in.
