This section takes you through each step in enabling the head pointer in macOS, with pictures of the screens to help you.
1. Click the Apple icon in the top left corner of the screen, then select System Preferences.
2. Click the Accessibility icon In the System Preferences window.
3. In the Accessibility window, scroll down the list on the left-hand side and select Pointer Control.
4. Click the Alternative Control Methods tab on the right.
5. Now look at the three options below and click the checkbox next to Enable head pointer.
6. The head pointer has some useful settings that adjust how it behaves. To access these, click the Options button opposite Enable head pointer.
7. You can use a keyboard switch to pause and resume using the head pointer. To enable this, click the checkbox next to Use a switch to pause or resume head pointer.
8. To change which key pauses and resumes the head pointer, click the Reassign button on the right and tap a new key. This will be the key you use in future to pause and resume using the head pointer feature.
9. To change the pointer speed and make it move faster or slower, increase or decrease the value in the Pointer speed box. Click OK when you're finished.
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 this is the case, you will need to contact them to access these settings or for further help.
