How to disable iCloud acceleration in OS X Server 5

The Caching service in OS X Server 5 lets you store local copies of iCloud content for your users. You can disable or re-enable this service as needed.

OS X Server 5 adds the ability to cache iCloud content so that users with more than one device on the same network can sync iCloud data faster. This information is securely encrypted in transit as well as on the caching server’s disk.

If your organization would prefer to avoid caching iCloud data, you can disable this feature using this Terminal command:

sudo serveradmin settings caching:AllowPersonalCaching = no

If you later want to re-enable the setting, use this command:

sudo serveradmin settings caching:AllowPersonalCaching = yes
