The payload for configuring the content-caching service.
- macOS 10.13.4+
true, allows the system to purge content from the cache automatically when it needs disk space for other apps (i.e. when free disk space runs low on the computer). Customers who want content caching to be as effective as possible should set this to
true, caches the user's iCloud data. Clients may take some time (hours or days) to react to changes to this setting; it doesn't have an immediate effect.
At least one of the
Allow keys must be
true, caches non-iCloud content, such as apps and software updates. Clients may take some time (hours, days) to react to changes to this setting; it does not have an immediate effect.
At least one of the
Allow keys must be
true, automatically activates the content cache when possible and prevents it from being disabled.
The maximum number of bytes of disk space that will be used for the content cache. A value of 0 means unlimited disk space.
The path to the directory used to store cached content. Changing this setting manually doesn't automatically move cached content from the old location to the new one. To move content automatically, use the Sharing preference's Content Caching pane. The value must be (or end with)
A directory and its intermediates are created for the given data path if it doesn't already exist. The directory is owned by
_assetcache: and has mode 0750. Its immediate parent directory (
.../Library/Application Support/Apple/Asset) is owned by
_assetcache: and has mode
true, disables tethered caching.
true, content caching displays exceptional conditions (alerts) as system notifications in the upper corner of the screen. Alerts were automatically displayed starting in macOS 10.13. In macOS 10.15 these were turned off by default, but are still available via this setting.
true, prevents the computer from sleeping as long as content caching is on (System Preferences > Sharing > Content Caching is on). Customers who want content caching to be as available as possible should set this to
An array of dictionaries describing a range of client IP addresses to serve.
true, the content cache provides content to the clients in the
Listen. To use the
Listen key, the
Listen key must also be specified.
With Peers And Parents
true, the content cache provides content to the clients in the union of the
true, the content cache offers content to clients only on the same immediate local network only. No content is offered to clients on other networks reachable by the content cache. If
Local is set to
Listen will be ignored.
true, the content cache logs the IP address and port number of the clients that request content.
An array of the local IP addresses of other content caches that this cache should download from or upload to, instead of downloading from or uploading to Apple directly. Invalid addresses and addresses of computers that aren't content caches are ignored. Parent caches that become unavailable are skipped. If all parent content caches become unavailable, the content cache downloads from or uploads to Apple directly, until a parent content cache becomes available again.
The policy to implement when choosing among more than one configured parent content cache. With every policy, parent caches that are temporarily unavailable are skipped.
first-available: Always use the first available parent in the Parents list. Use this policy to designate permanent primary, secondary, and subsequent parents.
url-path-hash: Hash the path part of the requested URL so that the same parent is always used for the same URL. This is useful for maximizing the size of the combined caches of the parents.
random: Choose a parent at random. Use this policy for load balancing.
round-robin: Rotate through the parents in order. Use this policy for load balancing.
sticky-available: Use the first available parent that is available in the Parents list until it becomes unavailable, then advance to the next one. Use this policy for designating floating primary, secondary, and subsequent parents.
An array of dictionaries describing a range of peer IP addresses that the content cache uses to filter its list of peers to query for content. The content cache only queries peers in
Peer is an empty array, the content cache doesn't query any peers.
An array of dictionaries describing a range of peer IP addresses the content cache responds to. When
Peer is an empty array, the content cache responds with an error to all cache queries.
Local Subnets Only
true, the content cache only peers with other content caches on the same immediate local network, rather than with content caches that use the same public IP address as the device. When
true, it overrides the configuration of
Peer. If the network changes, the local network peering restrictions update appropriately. If
false, the content cache defers to
Peer for configuring the peering restrictions.
The TCP port number on which the content cache accepts requests for uploads or downloads. Set the port to 0 to pick a random, available port.
An array of dictionaries describing a range of public IP addresses that the cloud servers should use for matching clients to content caches.
