How to display a larger version of text when you hover the pointer over it in macOS 26 Tahoe

7. The modifier key is the key you hold down whilst moving the pointer over the text you want to read. By default, this is the Command key.  To change it, click the Activation Modifier drop-down menu and choose Control (⌃), Option (Alt ⌥), or Command (⌘).

8. You can lock Hover Text so that you don’t need to keep holding down the modifier key to magnify text. Turn on the toggle switch for Triple press modifier to set activation lock.  When you triple-press the modifier key, Hover Text will be turned on and locked. To unlock it, triple-press the modifier key again.

9. To change the size of the Hover Text, choose a new size from the Text size selector.

10. To change the font used for Hover Text, choose from the options in the Text Font drop-down menu.

11. C­hoose the colours for each element of Hover Text 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.
