How to View Update Log on a Mac


Apple's App Store gives OS X users a condensed list of updates that have been performed in the past 30 days. This is a handy place to go if you want to quickly see when you last installed iTunes or other software in the past month. For the more detail-oriented users, OS X also offers a comprehensive log of every update ever installed on your Mac. This log includes security updates, third-party utilities, foreign word lists and each of the several dozen iTunes updates you may have installed in the past couple of years.

See Recent Updates

  • Launch the App Store on your Mac from the dock or press "Command-Space" on the keyboard, type "App Store" and click the "App Store" link in Spotlight.

  • Click the "Updates" icon at the top of the App Store window. As well as listing any updates that should be installed, this window lists all the updates added to your Mac in the past 30 days.

  • Click the "Purchases" icon to see all the applications you have downloaded from the App Store since it launched in January 2011. Although this doesn't give you update information, the App Store does give you the date you purchased the app or opted to download it if it was free.

Review Every Update

  • Click the "Apple" menu and select "About This Mac" from the drop-down menu. This first window gives you basic information about your computer, like its current version of OS X, its processor and how much memory it has.

  • Click the "More Info" button to view a bit more information about the Mac, including its model and graphics card.

  • Click the "System Report" button and scroll to the Software section in the left menu. Select "Installations." This is the place to find all the software and updates that have been added to your Mac, including the version number, the source of the installation and the date that version or update was installed.

  • Scroll down the list to see all the updates performed for any application, utility or different parts of the OS X operating system. The list includes applications you downloaded from the Apple App Store, updates sent to you directly from Apple and third-party software downloaded from other websites. To organize the list by date, click the "Install Date" header.
