+  Disable mouse acceleration with this one weird trick.
+---
+
+## Acceleration
+
+
+### Disabling
+
+```bash
+defaults write .GlobalPreferences com.apple.mouse.scaling -1
+```
+
+Note: Log out to take effect. If you change *Tracking Speed* under System Preferences, it will undo this fix. Only affects the mouse, not the trackpad.
+
+## Re-enabling
+
+Under *System Preferences* → *Mouse*, change *Tracking Speed*.
+
+### Trackpad acceleration
+
+```bash
+defaults write .GlobalPreferences com.apple.trackpad.scaling -1
+```
+
+Works the same way.
