This section explains how to enable Hover Colour in macOS 26 Tahoe. This is a step-by-step guide 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 Accessibility in the sidebar.

3. Select Hover Text from the list of Accessibility options on the right.

4. On the next page, click the toggle switch for Hover Colour to turn it on.

5. To use Hover Colour, hold down the Ctrl (Control ⌃) key and move the pointer over an item on the screen. Try it now — it works on items in System Settings!

6. To customise the settings for Hover Colour, click the settings button
next to the toggle switch.

7. The modifier key is the key you hold down while moving the pointer over an item to display its colour. By default, this is the Control (⌃) key. To change it, click the Activation Modifier drop-down menu and choose Control (⌃), Option (Alt ⌥), or Command (⌘).

9. To change the text size in the Hover Colour window, select your preferred size using the Text Size selector.

10. To change the font used in Hover Colour, select an option from the Text Font drop-down menu.

11. Choose the colours for each element of Hover Text — Text Colour, Background Colour, and Border Colour — from the options in the Appearance section.

12. When you are happy with your settings, click Done.

13. 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.
