Description

This cookbook has two resources for managing local user settings on OS
X:

• mac_os_x_plist_file - manages "plist" settings files for OS X applications.
• mac_os_x_userdefaults - manages settings in OS X's defaults(1) system.

This cookbook also includes a number of helper recipes.

Requirements

Platform

Tested on Mac OS X 10.6.8, 10.7.2 and 10.8.3.

Attributes

• node['mac_os_x']['settings_user'] - Used in the mac_os_x::settings recipe, this specifies the user to apply settings using mac_os_x_userdefaults LWRP. Defaults to the user currently running Chef (node['current_user']).
• node['mac_os_x']['settings'] - A hash of settings to apply with the mac_os_x_userdefaults LWRP (see below), used in the mac_os_x::settings recipe. Set up sub-attributes for each domain's settings to apply. The attribute must be a hash, and must have a "domain" key with the domain of the defaults setting. Each key is a "key" used in the LWRP, and its value is the corresponding "value"

For example, some 'dock' settings (for com.apple.dock):

node.default['mac_os_x']['settings']['dock'] = {
  "domain" => "com.apple.dock",
  "no-glass" => true,
  "autohide" => true,
  "showhidden" => true
}

Resource/Provider

mac_os_x_userdefaults

Manage the Mac OS X user defaults(1) system. The parameters to the
resource are passed to the defaults command and the parameters follow
convention of the OS X command. See the defaults(1) man page for
detail on how the tool works.

Actions

• :write: write the setting to the specified domain. Default.

Attribute Parameters

• domain: The domain the defaults belong to. Required. Name attribute.
• global: Whether the domain is global. Can be true or false. Default false.
• key: The preference key. Required.
• value: The value of the key. Required.
• type: Value type of the preference key.
• user: User for which to set the default.
• sudo: Set to true if the setting requires privileged access to modify. Default false.

value settings of 1, TRUE, true, YES or yes are treated as
true by defaults(1), and are handled in the provider.

value settings of 0, FALSE, false, NO or no are treated as
false by defaults (1) and are also handled by the provider.

Limitations

The current version cannot handle plists or dictionaries.

Examples

Simple example that uses the com.apple.systempreferences domain,
with a single key and value.

mac_os_x_userdefaults "enable time machine on unsupported volumes" do
  domain "com.apple.systempreferences"
  key "TMShowUnsupportedNetworkVolumes"
  value "1"
end

Specify a global domain. Note that the key is not required for global domains.

mac_os_x_userdefaults "full keyboard access to all controls" do
  domain "AppleKeyboardUIMode"
  global true
  value "2"
end

A boolean type that uses truthiness (TRUE).

mac_os_x_userdefaults "finder expanded save dialogs" do
  domain "NSNavPanelExpandedStateForSaveMode"
  global true
  value "TRUE"
  type "bool"
end

A setting that uses an int (integer) type.

mac_os_x_userdefaults "enable OS X firewall" do
  domain "/Library/Preferences/com.apple.alf"
  key "globalstate"
  value "1"
  type "int"
end

LWRP's can send notifications, so we can change the Dock, and then
refresh it to take effect.

execute "killall Dock" do
  action :nothing
end

mac_os_x_userdefaults "set dock size" do
  domain "com.apple.dock"
  type "integer"
  key "tilesize"
  value "20"
  notifies :run, "execute[killall Dock]"
end

This setting requires privileged access to modify, so tell it to use
sudo. Note that this will prompt for the user password if sudo hasn't
been modified for NOPASSWD.

mac_os_x_userdefaults "disable time machine normal schedule" do
  domain "/System/Library/LaunchDaemons/com.apple.backupd-auto"
  key "Disabled"
  value "1"
  sudo true
end

mac_os_x_plist_file

Manages the property list (plist) preferences file with the
cookbook_file Chef resource. Files will be dropped in
Library/Preferences under the home directory of the user running
Chef.

Actions

• :create: create the file. Default.

Attribute Parameters

• source: file name to use in the files directory of the cookbook. Name attribute.
• cookbook: cookbook where the plist file is located.

Examples

Write the iTerm 2 preferences to
~/Library/Preferences/com.googlecode.iterm2.plist.

mac_os_x_plist_file "com.googlecode.iterm2.plist"

Recipes

The recipes in this cookbook provide example usage of the defaults(1)
LWRP, and have some useful system preference settings. They were
originally based on work done in Pivotal Labs workstation management
repository, though are new code given the LWRP rewrite.

• https://github.com/pivotalexperimental/wschef

dock_preferences

Turns on:

• auto hide
• magnification

Turns off:

• animation switching workspaces

Sets the tile size to really small.

finder

Sets Finder save dialogs to expanded by default.

firewall

Enables the OS X firewall.

kbaccess

Enables keyboard access to all window controls. In other words, "Tab"
will cycle focus to buttons instead of just text entry fields.

key_repeat

Set the default key repeat rate to fast and the delay to short.

screensaver

Enables password protection for screensaver and sets the delay to ask for password.

time_machine

Enable time machine to backup to unsupported devices like NAS drives or AFP shares.

settings

Iterates over the node['mac_os_x']['settings'] attribute (see
Attributes above) for domain settings to apply. The attributes file
has commented-out settings to use for examples; this attribute is by
default an empty hash. You are encouraged to set the attributes for
your own nodes through a role, rather than modifying the cookbook's
attributes file directly.

To set user defaults for a user other than the one running Chef,
change the node['mac_os_x']['settings_user'] attribute.

Recipes above which implement specific settings through
mac_os_x_userdefaults can be replaced entirely through the use of
attributes, and may be removed in favor of this in a future release.

Assumptions

There are a couple glaring assumptions made by this recipe.

• If the domain starts with /Library/Preferences, then sudo is set to true, as that is not user writable.
• If the domain is NSGlobalDomain, then global is set to true.
