High Sierra can cache all the following software and data: The benefits of content caching increase based on the number of Apple devices that are on your network, which makes content caching ideally suited to environments such as offices and schools, however it may also come in handy if you’re a huge Apple fan who simply owns a lot of Apple products! Since you’re not downloading the same content multiple times, content caching can speed up the process of updating all subsequent devices, while also reducing how much bandwidth you use, which is good news if you have a capped Internet connection! At this point, the software or data will be available for other local Macs, iOS devices and Apple TVs (known as “clients”) to access and use, so they don’t have to re-download their own version of this content from the Internet.įor example, when the first client on your network downloads a new version of macOS, it’ll cache this content, and any other Macs on this network will then be able to copy this update from the cache.

Once you’ve enabled content caching, every time you download supported software or data, your Mac will store this content locally.
