Apple introduced Reference Image, a new camera mode on iPhone 18 Pro designed to verify photograph authenticity through a chain-of-custody system that begins at sensor initialization during manufacturing. The system uses cryptographic signing, Private Cloud Compute processing, and quantum-resistant encryption to create verifiable digital negatives while preserving photographer anonymity and protecting against manipulation throughout the editing chain.
Apple released macOS Tahoe 26.7 and macOS Sequoia 15.8 alongside macOS 27 Golden Gate, featuring important security fixes recommended for all users. The updates include WebKit vulnerability patches, though full security details have not yet been published.
