How can I list all updates installed on Mac OS X?

  • The way updates are recorded has changed considerably between versions of OS X; both of the answers I see os far apply to Snow Leopard (10.6), so if you're concerned with another version, please specify. Oct 28, 2010 at 17:06

The list of all installed updates is located in /Library/Receipts/InstallHistory.plistif you don't want to use the Software Update preference pane.

  • includes lots of additional software installed (or not) in addition to the stuff managed by the OS.

  • There's also /var/db/receipts/, which contains plist and bom files for most of the entries in InstallHistory.plist.

System Prefs > Software Update > Installed Software.

Sort by date.

    The tab for installed updates was removed on 10.8.

Open the System Information application which can be found in /Applications/Utilities. Then go to Software -> Installations and there you have it.

This solution works on old and new versions of OS X (I've tested it on 10.8.2).

Use the following command:

/usr/sbin/system_profiler SPInstallHistoryDataType

Which is the command line alternative to "System Profile"

Do not rely on AppStore to tell you if you have the latest updates installed. It will lie to you.

Open the Terminal application and type the following and hit enter:

softwareupdate --history

Shows the Mac OS install history, including updates. By default, only displays updates installed by softwareupdate. To see all installs including Applications type the following and hit enter:

softwareupdate --history --all

Not sure if this works on older MacOS releases, but it works for High Sierra as of 10.13.4.
