softwareupdate(8) BSD System Manager's Manual softwareupdate(8)NAME
softwareupdate -- system software update tool
SYNOPSIS
softwareupdate command [args ...]
DESCRIPTION
Software Update checks for new and updated versions of your software based on information about your computer and current software.
Invoke softwareupdate by specifying a command followed by zero or more args.
softwareupdate requires admin authentication for all commands except --list. If you run softwareupdate as a normal admin user, you will be
prompted for a password where required. Alternatively, you can run softwareupdate as root and avoid all further authentication prompts.
The following commands are available:
-l | --list
List all available updates.
-i | --install
Each update specified by args is downloaded and installed. args can be one of the following:
-r | --recommended
All updates that are recommended for your system. These are prefixed with a * character in the --list output.
-a | --all All updates that are applicable to your system, including those non-recommended ones, which are prefixed with a -
character in the --list output. (Non-recommended updates are uncommon in any case.)
item ... One or more specified updates. The --list output shows the item names you can specify here, prefixed by the * or -
characters. See EXAMPLES.
-d | --download
Each update specified by args is downloaded but not installed. The values of args are the same as for the --install command.
Updates downloaded with --download can be subsequently installed with --install, or through the App Store (as long as they remain
applicable to your system). Updates are downloaded to /Library/Updates, but are not designed to be installed by double-clicking
the packages in that directory: always use --install or the App Store to actually perform the install.
--ignore identifier ...
Manages the per-machine list of ignored updates. The identifier is the first part of the item name (before the dash and version
number) that is shown by --list. See EXAMPLES.
--reset-ignored
Clears the per-machine list of ignored updates.
--schedule on | off
Manages the per-machine automatic (background) check preference.
-h | --help
Print command usage.
EXAMPLES
The following examples are shown as given to the shell:
softwareupdate --list
