Content caching on a Mac running macOS 10.13 or later can cache multiple types of content: apps (from the App Store), OS updates (for macOS, iOS, iPadOS), and iCloud data (e.g., documents, photos). This reduces bandwidth usage by storing content locally for networked devices. Options A, B, and C are all correct individually, but D encompasses them all, aligning with the capabilities outlined in theApple Platform Deployment Guide.
