On iPhone and iPad, go to Settings > Accessibility > Display & Text Size and turn on Show Borders. Apple documents a Show Borders setting in System Settings for macOS 27 and later, but its available guidance does not specify the Mac navigation steps.

Turn on Show Borders on iPhone or iPad

  1. Open Settings.
  2. Tap Accessibility.
  3. Tap Display & Text Size.
  4. Turn on Show Borders.

Apple says the setting can make onscreen elements—including controls, buttons, and Control Center—easier to see by adding borders around them. The feature is not documented as applying to every element in every app. Apple’s iPhone user guide and iPad user guide describe the setting.

What to know about Show Borders on Mac

Apple’s developer reference identifies a dedicated Show Borders setting in System Settings on macOS 27 and later. The reference does not provide the end-user steps for finding or changing it, so this guide cannot confirm a specific Mac navigation path. See Apple’s developer documentation.

For earlier macOS versions, Apple’s reference says the accessibilityShowBorders value is true when Increased Contrast is enabled. That developer-facing relationship does not establish that earlier releases include the same dedicated Show Borders toggle.
