Apple announced at last year’s WWDC that macOS Mojave will be the latest version of macOS to run 32-bit applications. With the public beta release of the next major version of macOS (macOS Catalina), now is here, and it is no surprise that Catalina has dropped support for 32-bit applications. Although most popular apps will not be affected by this change, some of your apps may no longer run under macOS Catalina.
If any of your applications have recently issued a warning at startup, saying “It is not optimized for Mac and needs to be updated”, it will not be available when you upgrade to macOS Catalina. If you haven’t encountered this warning, but want to know which applications on your Mac are still 32-bit, doing so is simple.
How to find 32-bit apps on Mac
If you are running macOS Mojave or earlier, please check which apps on your Mac are 32-bit as follows:
- Click the Apple icon in the upper left corner of the screen.
- Click on About this Mac.
- Click on System report…
- In the left pane, select Application field Subheading software.
- Click on 64 bit (Intel) The column header (usually the rightmost column) is used to sort the application list by this value.
- All apps No It is a 32-bit application.
Note that the 64-bit (Intel) column headings do Do not Appears in the report under macOS Catalina-apparently because 32-bit apps are no longer valid applications and will not appear in this report at all-so this check should be run before upgrading to macOS Catalina.
Just because an application is 32-bit now does not mean that it will not be 64-bit in the future.In fact, if Get from The value of the app is Mac App Store, apple, Or Identified developer, This application is likely to transition to 64-bit at some point in the future.
but if unknown, The application faces an uncertain future.
Why did Apple drop support for 32-bit applications in macOS Catalina?
What Apple must say on this issue is:
All modern Macs include a powerful 64-bit processor, while macOS runs advanced 64-bit applications that can access more memory and improve system performance. The technologies that define the Mac experience today (for example, metal graphics acceleration) only apply to 64-bit applications. To ensure that the applications you buy are as advanced as the Mac running them, eventually all future Mac software will eventually require 64-bit.
Which popular applications will stop working in macOS Catalina?
Older versions of some popular applications released by Adobe and Microsoft are still 32-bit and will cease to function. Both Adobe and Microsoft have released modern 64-bit versions of their applications, if you are a Creative Cloud / Office 365 subscriber, you will not encounter any problems because you will be able to download the latest versions of all applications and actually The 64-bit version of all applications may already be running on it.
However, if you have purchased and are still hanging on Illustrator CS5 or InDesign CS5 or Microsoft Office 2011 suite, you need to find an alternative.
Unless an update is released, the Android File Transfer application will also stop running.
My favorite application does not work in macOS Catalina-what are my options?
If your favorite application does not run in macOS Catalina, you can take the following measures:
Make sure you are running the latest version of the application.If you are not already using Catalina, please launch the app and go to on Screen (click the application name in the upper left corner, then click About the application name) to check the version of the application. Visit the developer’s website to see if a new version of the application is available.
Most non-App Store apps also allow you to check for updates from within the app from the app menu.You can click on the app name in the upper left corner and check if it exists Check for updates Options. Or, check for similar content in the app’s “Preferences”.
By default, the App Store application will automatically update, unless you disable automatic updates.
Contact the developer to see if there are plans to release an updated version of the application.
If the app is critical to your workflow, then obviously you can continue to run the version of macOS that is currently running and not upgrade to macOS Catalina until you find another way.
