The Hover Text is an accessibility feature that magnifies text relative to wherever your cursor is pointed on the screen. To enable this feature, you need to first sign in to your Mac and head over to System Preferences using the Menu bar or the dock. Click on the Accessibility tab inside the System Preferences window.  From the menu on the left-hand side, select Zoom; it should be under the Vision subsection. Next, check the box next to the Enable hover text option. Now, all you have to do is hold down the Command key and move the cursor to the text you want to magnify on the screen.
