MacOS Server’s Caching feature

PERMISSIONS

By default, the cache works only for devices on your network; it’s best, then, to leave these settings alone.

ICLOUD DATA

If you use iCloud Drive, check this box in order to speed up syncing its data among all your devices.

CACHE LOCATION

This setting enables you to pick an external drive with more space to store cached data.

CACHE SIZE

If space is an issue, use this slider to limit the cache’s size. Clicking ‘Reset’ will clear the entire cache.
