Content caching on a Mac (macOS 10.13 or later) doesn't require an Apple ID, Managed Apple ID, or Personal Apple ID to function. It's a system-level feature enabled in macOS settings or via MDM, caching content like app updates and iCloud data for network efficiency. While iCloud caching benefits from a user's Apple ID on client devices, the caching Mac itself doesn't need one. The Apple Platform Deployment Guide confirms no Apple ID is required for content caching setup.
