Discussion

Content Caching must be disabled. Content Caching is a macOS service that helps reduce internet data usage and speed up software installation on Mac computers. It is not recommended for devices furnished to employees to act as a caching server.

Check Content

Verify the macOS system is configured to disable Content Caching service with the following command:

/usr/bin/osascript -l JavaScript << EOS
$.NSUserDefaults.alloc.initWithSuiteName('com.apple.applicationaccess')\
.objectForKey('allowContentCaching').js
EOS

If the result is not "false", this is a finding.

Fix Text

Configure the macOS system to disable Content Caching service by installing the "com.apple.applicationaccess" configuration profile.
