With tethered caching, a Mac can not only share its Internet connection with iOS devices connected to it via USB but automatically cache downloaded content. MacOS Sierra 10.12 and iOS 10.3 and later support tethered caching. The feature keeps a copy of software updates, apps and other content that local networked clients download from the Internet on your designated Mac computer.īecause your Internet connection is slower than your local Ethernet or Wi-Fi connection, client devices retrieve cached content a lot faster without going out over the Internet. Here’s how to set up and use this feature to avoid repeated downloads and reduce bandwidth usage.Ĭontent caching used to be limited to macOS Server, but is now available in macOS High Sierra 10.13 and newer. The serverctl command is pretty simple to use.Mac content caching cuts down your Internet data usage and accelerates downloads on iPhone, iPad, Mac, Apple Watch and Apple TV dramatically. One of these new options is serverctl, located in /Applications/Server.app/Contents/ServerRoot/usr/sbin/. But while deploying OS X Server can seem like a pretty manual process, Apple has quietly been building new options and features behind the scenes. Ever since OS X Server became an app that you deploy on a Mac Mini, it's become increasingly difficult to deploy en masse. Once upon a time, we had tools like AutoServerSetup, a file that could be deployed to automate server setups. Services such as the Software Update service, Profile Manager, the Caching service, and many others provide a unique benefit and increase the viability of Mac and iOS deployment. OS X Server provides a solid contribution to many environments.
