Making text bigger in Mac OS

Open System Preferences and click Displays to display its preferences.
Click the Display tab; your display's supported resolution settings are listed in the Resolutions pane, from the lowest to the highest resolution.
Select any of the choices to change the resolution. A lower resolution gives you less desktop space to display windows and interfaces, but these will also appear larger. A larger resolution maximizes your screen space, letting you see more of a photo or document, but your text and icons will be smaller.
