Appendix: Apple Silicon Runtime Configuration Consumers

The daemons and services on a node whose configuration can change at runtime.

Overview

A Google Cloud node has no equivalent tables: it carries its configuration inside the measured container image and receives Measured, unmeasured, and dynamic configuration through the control-plane agent. For an overview of both, see Runtime Configuration and Assets.

CloudConfigurationPreferences framework consumers

The following daemons expose hot properties managed by cloudconfigurationd through the CloudConfigurationPreferences framework.

Daemon	Hot-properties CFPrefs domain
`cb_attestationd`	`com.apple.cloudos.hotproperties.cb_attestationd`
`cb_jobhelper`	`com.apple.cloudos.hotproperties.cb_jobhelper`
`cloudboardd`	`com.apple.cloudos.hotproperties.cloudboardd`
`splunkloggingd`	`com.apple.cloudos.hotproperties.splunkloggingd`
`tie-controllerd`	`com.apple.cloudos.hotproperties.tie`

ServiceControl framework consumers

The following services use the ServiceControl framework to define behavior in response to instructions delivered by the PCC control plane through controlplaneagent.

Service	Service identifier	Instructions	Properties
`tie-controllerd`	`com.apple.tie-controllerd.from.control-plane-agent`	`activate`, `deactivate`	`ModelSwitchingProperty` (switches the active model)
`cloudassetdownloaderd`	`com.apple.cloudos.cloudassetdownloaderd`	`activate`, `deactivate`	`applicationAssetMap` (assets to download per consumer)

Cloud asset distribution consumers

cloudboardd subscribes to Cloud asset distribution from cloudassetdownloaderd through the CloudAssetDownloaderFramework on behalf of the following consumers.

Consumer ID	Consumer	Use
`PCCSafetyOverrideAssets`	PCC Agent	Pccagent
`CipherMLAssets`	CipherMLSE	Pir
