DESCRIPTION
The installer command is used to install Mac OS X installer packages to a
specified domain or volume. The installer command installs a single
package per invocation, which is specified with the -package parameter (
-pkg is accepted as a synonym). It may be either a single package or a
metapackage. In the case of the metapackage, the packages which are part
of the default install will be installed unless disqualified by a pack‐
age's check tool(s).
The target volume is specified with the -target parameter ( -tgt is
accepted as a synonym). It must already be mounted when the installer
command is invoked.
For system software installs, the target volume must be a different vol‐
ume than the one currently running the booted system. See systemsetup
(only available on Mac OS X Server) to set the boot volume.
The installer command requires root privileges to run. If a package
requires authentication (set in a package's .info file) the installer
must be either run as root or with the sudo(8) command (but see further
discussion under the -store option).
The installer is not responsible for rebooting the machine after
installing. Use reboot(8) or shutdown(8)-r now to reboot the system.
The installer displays two forms of output. The default terse output is
intended for parsing by scripting languages for automating (or scripting)
installs and verbose output providing additional information and descrip‐
tive error messages.
A list of flags and their descriptions:
-dominfo
Displays a list of domains into which the software package can be
installed. For example: LocalSystem or CurrentUserHomeDirectory.
The domains listed are those which are available and enabled when
the command is run.
-volinfo
Displays a list of volumes onto which the software package can be
installed. The volumes listed are the mounted volumes available
when the command is run.
-pkginfo
Displays a list of packages that can be installed onto the target
volume. If a metapackage is given as the package source, all of
its subpackages are listed.
-query flag
Queries a package for information about the metadata. See -help
for supported flags.
-allowUntrusted
Allow install of a package signed by an untrusted (or expired)
certificate.
-dumplog
Detailed log information is always sent to syslog using the
LOG_INSTALL facility (and will wind up in /var/log/install.log).
-dumplog additionally writes this log to standard error output.
-help Displays the help screen describing the list of parameters.
-verbose
Displays more descriptive information than the default output.
Use this parameter in conjunction with -pkginfo and -volinfo
information requests to see more readable output. The default
output is formatted for scripting.
-verboseR
Displays same information as -verbose except the output is for‐
matted for easy parsing.
-vers Displays the version of this command.
-config
Formats the command line installation arguments for later use.
The output is sent to stdout, but can be redirected to a file to
create a configuration file. When specifying this option, an
installation is not actually performed. This configuration file
can be supplied as the argument to the -file parameter instead of
typing a long series of installation arguments. The config file
can be used to perform multiple identical installs. You can cre‐
ate a config file as follows:
installer-pkg ~/Documents/Foo.pkg -target / -config > /tmp/con‐
figfile.plist
-plist Formats the installer output into an XML file, which is sent by
default to stdout. Use this parameter for -dominfo, -volinfo,
and -pkginfo
-file pathToFile
Specifies the path to the XML file containing parameter informa‐
tion in the key/value dictionary. This file can be used instead
of the command line parameters, and supersedes any parameters on
the command line. When you type this parameter, you type the
path to the XML file. Use with config file generated by -config
For example:
installer-file /tmp/configfile.plist
-lang ISOLanguageCode
Default language of installed system (ISO format). This is only
necessary when performing a system (OS) install, otherwise is it
ignored. There is no verification done to make sure that the
language being set actually exists on the machine, however the
ISO language code is verified to ensure that it is valid.
-listiso
Display the list of valid ISO language codes the installer recog‐
nizes.
-showChoiceChangesXML
Prints to stdout the install choices for the package (specified
with -pkg) in an XML format. This allows choice attributes to be
modified and applied at install-time using
-applyChoiceChangesXML. See CHOICE CHANGES FILE for details of
this XML format.
-applyChoiceChangesXML pathToXMLFile
Applies the install choice changes specified in pathToXMLFile to
the default choices in the package before installation. This
allows the command-line installer to customize choice what gets
installed. See CHOICE CHANGES FILE for details of this XML for‐
mat. Any problems encountered while applying the choice changes
will be reported to the LOG_INSTALL facility (i.e. to
/var/log/install.log), and also to stdout if -dumplog is used.
-showChoicesAfterApplyingChangesXML pathToXMLFile
Applies the install choice changes specified in pathToXMLFile to
the default choices in the package, and then dumps the resulting
choice state to stdout. The input and output XML format is as
described in CHOICE CHANGES FILE. Since changing one choice in a
package can implicitly change other choices, this option allows
you to confirm that a particular choiceChanges file will have the
intended effect. You must specify a -target when using this
option, since the evaluated choices can also change with the
state of the target disk.
-showChoicesXML
Prints to stdout the install choices for the package (specified
with -pkg) in a hierarchical XML format. This is not the same
format as used with -applyChoiceChangesXML. This option is pro‐
vided for System Image Utility only.
-store Install the product archive specified by -package, in the same
way that it would be installed through the Mac App Store. In this
mode, no other options are supported. (You can specify -target,
but the only allowable value is the root volume mount point, /).
For best Mac App Store fidelity, run installer as an admin user
(not using sudo); you will prompted for your admin user's pass‐
word before the install begins.
This mode is provided for testing a product archive before sub‐
mission to the Mac App Store. See productbuild(1) for how to cre‐
ate a product archive.
DEVICES
A device parameter for the target is any one of the following:
1) Any of the values returned by -dominfo
2) The device node entry. Any entry of the form of /dev/disk*. ex:
/dev/disk2
3) The disk identifier. Any entry of the form of disk*. ex: disk1s9
4) The volume mount point. Any entry of the form of /Volumes/Mountpoint.
ex: /Volumes/Untitled
5) The volume UUID. ex: 376C4046-083E-334F-AF08-62FAFBC4E352
CHOICE CHANGES FILE
A “choiceChanges” file allows individual installer choices to be selected
or deselected. A template choiceChanges file for a given package can be
generated with the -showChoiceChangesXML option, and is interpreted as
follows.
The choiceChanges file is a property list containing an array of dictio‐
naries. Each dictionary has the following three keys:
Key Description
choiceIdentifier Identifier for the choice to be modified (string)
choiceAttribute One of the attribute names described below (string)
attributeSetting A setting that depends on the choiceAttribute,
described
below
(number
or
string)
The choiceAttribute and attributeSetting values are as follows:
choiceAttribute attributeSetting Description
selected (number) 1 to select the choice, 0 to deselect it
enabled (number) 1 to enable the choice, 0 to disable it
visible (number) 1 to show the choice, 0 to hide it
customLocation (string) path at which to install the choice (see
below)
Note that there can be multiple dictionaries for the same
choiceIdentifier, since there can be multiple attributes set for a single
choice.
The customLocation attribute can be set for a choice only if that choice
explicitly allows a user-defined path. That is, if the choice would have
a Location popup when viewed in the Customize pane of the Installer
application, it can be set via customLocation. (Otherwise, installation
paths cannot be arbitrarily modified, since the package author must
account for custom install locations for the installation to work prop‐
erly.)
