How to check the size of app updates in the Mac App Store

Want to see the size of an app update that is available in the Mac App Store? Some Mac users may be interested in knowing the size of an available app software update before starting to download or install the app update, but the App Store in MacOS Mojave doesn’t openly display the size of available app updates by default. Instead, you’ll need to dig a little deeper to see the size of an app update in the Mac App Store.

How to See the Size of App Updates in Mac App Store

To check the size of an available app update before you start to download it, do the following:

  1. Open the Mac App Store
  2. Mac App Store

  3. Go to the “Updates” tab to find the available app software updates
  4. To find the size of an app update, click the small “More” button

  6. See the size of the app update in the little popup window
  7. How to see the size of Mac App Store updates before downloading them

The “More” button will also reveal the downloads release notes from the developer of the application, as well as the release date of the particular software update. But of course for our purposes here we’re focusing on the size of the available update.

Many Mac users will appreciate knowing the size of available app updates before beginning the process of downloading and installing them, particularly if they’re on slower internet connections or have metered broadband service with limited bandwidth or tight data caps.

Of course once you start downloading the updates you can also check their download progress from the Mac App Store, but knowing the download size after the fact is not always as helpful as knowing it before you begin an update.

    This is not correct. The ‘more’ button displays the size of the application, not the update. Tested this on 2 separate apps and the updates downloaded significantly faster than possible on my internet connection.

    What a joke this new App Store. If Apple can not do any better than this then it explains why they are losing their competitive edge on computers and smartphones.

    This is helpful, and an improvement over the prior App Store which did not show the update size at all of app updates available.

    But I wish it was displayed the update size immediately for all updates directly under the date or something of the update, make that information visible and obvious. I have data caps and am in a rural area with fairly slow internet connection compared to any city, and so starting multiple GB of downloads can be more complex than just clicking the button as you have to consider the effect on the rest of the network and other internet activity, plus the reliability isn’t high. That’s the nature of rural internet, which by the way is only an hour outside of a major US city.

    Sometimes I think Apple only tests their software and hardware in the Silicon Valley. Maybe Apple engineers should have to test all of their work on a slow typical DSL connection, where iCloud is not doable and downloading large software updates is an ordeal.
