If you\u2019re running macOS 10.13.4 High Sierra or macOS 10.14 Mojave, you may have seen a dialog that says an app isn\u2019t optimized for your Mac. The message differs slightly between High Sierra and Mojave, with the High Sierra version telling you the developer needs to update the app to improve compatibility whereas Mojave saying bluntly that the app won\u2019t work with future versions of macOS.<\/p>\n

What\u2019s going on here, what should you do, and when should you do it?<\/p>\n

What\u2019s Going On: 32-bit and 64-bit Apps<\/h3>\n

Over a decade ago, Apple started to transition all the chips used in Macs, along with macOS itself, from a 32-bit architecture to a 64-bit architecture. Without getting into technical details, 64-bit systems and apps can access dramatically more memory and enjoy significantly faster performance.<\/p>\n

Apple knew it would take years before most people were running 64-bit hardware and 64-bit-savvy versions of macOS, so it allowed macOS to continue running older 32-bit apps. However, maintaining that backward compatibility has a cost, in terms of both performance and testing, so at its Worldwide Developer Conference in 2017, Apple warned developers that High Sierra would be the last version of macOS to support 32-bit apps \u201cwithout compromise.\u201d At the next WWDC in June 2018, Apple announced that macOS 10.14 Mojave would be the last version of macOS to run 32-bit apps.<\/p>\n

Happily, the only \u201ccompromise\u201d for 32-bit apps in Mojave is the warning dialog, which appears every 30 days when you launch an older app. But the writing is on the wall: 32-bits apps will cease working in macOS 10.15.<\/p>\n

How Do You Identify 32-bit Apps?<\/h3>\n

Apple provides a tool to help you find 32-bit apps. Follow these steps:<\/p>\n

    \n
  1. From the Apple menu, choose About This Mac and then click the System Report button.
    \n\"\"<\/li>\n
  2. In the System Information utility that opens, scroll down to Software in the sidebar and select Applications. It may take a few minutes to build the list of every app on all mounted drives.<\/li>\n
  3. When it finishes, click the 64-bit column header (No means 32-bit; Yes means 64-bit) to sort the list, and select an app to see its details in the bottom pane.
    \n\"\"<\/li>\n<\/ol>\n

    This technique works in both High Sierra and Mojave, but in Mojave, System Information includes a better-formatted section, called Legacy Software, that also provides a list of 32-bit apps. However, this list may be smaller because it includes only those apps that you\u2019ve launched. Since it\u2019s likely that you open old 32-bit apps only occasionally, you can\u2019t trust the Legacy Software list to be complete.<\/p>\n

    \"\"<\/p>\n

    If you find System Information\u2019s Applications list overwhelming, check out the free 32-bitCheck<\/a> utility from Howard Oakley. It performs exactly the same task but lets you focus on a particular folder and save the results to a text file for later reference.<\/p>\n

    \"\"<\/p>\n

    What\u2019s Your Next Step?<\/h3>\n

    Once you know which apps won\u2019t work in macOS 10.15, you can ponder your options. Luckily, you have some time. We expect Apple to release macOS 10.15 in September 2019, but you don\u2019t need to upgrade right away\u2014in fact, we recommend that you wait a few months after that to allow Apple time to fix bugs.<\/p>\n

    That said, we do encourage upgrading eventually, and if you buy a new Mac after September 2019, it will come with macOS 10.15. So you need to establish a plan\u2014it\u2019s better to know what you\u2019re going to do than to be forced into action if you have to replace your Mac on short notice. For each 32-bit app on your Mac, you have three options:<\/p>\n

      \n
    • Delete it:<\/b> It\u2019s not uncommon to have old apps that you haven\u2019t used in years and won\u2019t miss. There\u2019s no need to waste drive space on them in macOS 10.15.<\/li>\n
    • Upgrade it:<\/b> Apps in active development will likely have a new version available. The main questions are how much the upgrade will cost and if there are compatibility issues associated with upgrading. You can upgrade at any time, although it\u2019s likely worth waiting until you\u2019re ready to move to macOS 10.15 to minimize costs. The apps that cause the most irritation here are things like the Adobe Creative Suite\u2014Photoshop, Illustrator, and InDesign\u2014that require switching to a monthly subscription.<\/li>\n
    • Replace it:<\/b> If no upgrade is available, the cost of upgrading is too high, or upgrading comes with other negatives, it\u2019s time to look for an alternative. This can take some time, so it\u2019s worth starting soon to ensure that the replacement will provide the features you need before macOS 10.15 forces the decision.<\/li>\n<\/ul>\n
