MACOSX_DEFAULTS_READ

The "MACOSX_DEFAULTS_READ" audit check examines the default system values on Mac OS X. This check behaves differently if you set certain properties.

  • If you set plist_user to all, all user settings are audited, otherwise the specified user setting is audited. In other words, you can only audit all users or one specific user.

  • If you set byhost to YES in addition to the plist_user property being set, the following query runs:

    /usr/bin/defaults -currentHost read /Users/foo/Library/Preferences/ByHost/plist_name plist_item

  • If you do not set byhost and you set plist_user, the following query runs:

    /usr/bin/defaults -currentHost read /Users/foo/Library/Preferences/plist_name plist_item

  • If you do not set byhost or plist_user, the following query runs:

    /usr/bin/defaults -currentHost read plist_name plist_item

The following properties are supported:

Property Description Accepted Value
plist_name The plist that you want to query.

Example:

com.apple.digihub

plist_item The plist item that you want to audit.

Example:

com.apple.digihub.blank.cd.appeared

plist_option If you set this property to CANNOT_BE_NULL, the check fails if the setting being audited is not set. CANNOT_BE_NULL
byhost If you set this property YES, the query results are generated by host. YES
not_regex Ensures that all found items do no match a specified regex.

Example:

not_regex: ".* = 6"

managed_path Specifies a custom path that contains the plist.

Example:

managed_path: "/Library/Managed\ Preferences/"
