Overview

• The third beta of macOS Tahoe 26 contains code artifacts that indicate Apple is developing a sealed-device update system for Macs modeled on its iPhone Presto technology.
• On iPhones, Presto uses a proprietary Mac mini–controlled ‘two-slot toaster’ and NFC signals to update sealed boxes without opening them.
• Current Macs lack NFC hardware; Apple would need to add NFC in future models or use Bluetooth to initiate wireless updates.
• Implementing Presto for Macs could ensure new machines ship preloaded with the latest macOS and prevent setup failures linked to day-one patches.
• Apple has not announced a rollout schedule for sealed-box Mac updates; logistics and activation methods remain unresolved.
