If you keep losing track of your Mac's tiny cursor, you can make it bigger by going to System Preferences > Accessibility > Display and moving the slider to the right for Cursor size. (You'll find similar options for text and icons in Finder by opening a Finder window and clicking View in the menu bar and then choosing Show View Options.) 4. Right-click on the desktop, choose Show View Options and you'll get options for increasing Icon size and Text size. If your desktop icons are too small to be useful, you can increase their size along with the text of their descriptions. And to return to the normal zoom level, hit Command-Zero. You can then lower it by hitting Command-Minus.

In many other apps, including both Chrome and Safari, you can increase text size (along with everything else) by hitting Command-Plus. Similarly, in the Messages app, go to Messages > Preferences > General and move the slider at the bottom for Text size to the right. Having troubling reading emails? Well, in the Mail app, you can bump up the font size by opening the Mail app and going to Mail > Preferences > Fonts & Colors and clicking the Select button next to Message font and choosing a font size larger than the default of 12. If you don't have a Retina display, you can still make text bigger on an app-by-app basis. Choose one of the two options on the Larger Text side to make it easier to read what's on your display. Choose Scaled and, depending on the size of your Retina display, you'll have four or five options. On the Display tab, you'll see two options at the top of the window for Resolution: Default for display and Scaled. Open System Preferences and go to Displays. Retina displays offer what Apple calls 'scaled resolutions' to bump up size of text and icons. That's never a great idea anyway because you lose sharpness in the bargain for larger, more legible letters. For Macs with Retina displays, you can't lower the native resolution to a specific resolution in order to increase the size of text and icons like you can on other laptops and displays.
