BlurShield blurs your screen the instant your lid starts closing, a paired device goes out of range, or you hit a keyboard shortcut — Touch ID brings it right back. Choose what protects you: a lid-angle sensor, a Bluetooth device that walks out of range with you, or a shortcut you trigger yourself. BlurShield also includes Espresso, a caffeinate replacement built in: keep your Mac awake through long builds, renders, or downloads, without digging through Energy Saver settings every time.
