This section gives you step by step instructions on how to slow down the mouse in macOS 13 Ventura, with pictures of the screens to help.
1. Click the Apple icon in the top left corner of the screen and choose System Settings from the menu.
2. In the System Settings window, click Mouse in the sidebar.
3. On the Mouse settings screen, Apple Magic Mouse users can only change the tracking speed. To change the scrolling speed, Apple Magic Mouse users need to follow step 4. If you are using a different mouse you can change both the tracking speed, and the scrolling speed on the same screen.
Apple Magic Mouse: Adjust the slider for Tracking speed to change how quickly the pointer moves.
Other mice: Adjust the slider for Tracking speed to change how quickly the pointer moves. Adjust the slider for Scrolling speed to change how quickly pages scroll.
4. Click the Apple icon in the top left corner of the screen and choose System Settings from the menu.
4. In the System Settings window, Select Accessibility in the sidebar.
5. Select Pointer Control from the list of Accessibilty options on the right.
6. On the Pointer Control page, click the Mouse Options button.
7. In the pop-up window, adjust the slider for Scrolling speed to change how quickly pages scroll.
8. By default, scrolling uses an inertia effect. With this effect enabled the page carries on scrolling a little further after you stop scrolling the mouse. To disable this effect, click the toggle switch for Use inertia when scrolling to turn it off.
9. If you would prefer to disable scrolling, click the toggle switch for Use mouse when scrolling to turn it off.
10. Click the OK button to save your changes.
11. When you are happy with your settings, close System Settings by clicking the Close button (red circle) in the top-left corner of the window or using the Cmd + W keyboard shortcut.
Note: If this does not work it could be because your computer settings are managed by someone else (an IT department or administrator for example). If so, you will need to contact them to access these settings or for help.
