Apr 13, 2018 Ironically, for most people, the 32-bit list will be dominated by Apple apps. Apple’s DVD player, and InkServer applications still lack native 64-bit support. Oct 12, 2019 Apple first announced that it would ultimately wind down support for 32-bit apps more than a year and a half ago, when it began pushing alerts to macOS High Sierra users that 32-bit.
Apple was phasing out the use of 32-bits applications on macOS for quite some time. Now the finishing time has come that the version 10.15 or macOS Catalina will no more support 32-bit applications. If you are still running old and unsupported applications in macOS Mojave or earlier versions then you need be cautious before upgrading to macOS Catalina. In this article, we will explain how to check 32-bit and 64-bit apps in macOS.
What Happens When You Open 32-bit Apps?
As of macOS Mojave, Apple will show a warning message whenever you open 32-bit apps. The best example of 32-bit app on macOS is Microsoft Office 2011. Whenever you open the app, macOS will show you a message like below indicating that the app is outdated and not optimized for your Mac.
However, you can still click on the “OK” button to continue using the app. Unfortunately, this is no more possible with macOS Catalina. When the 32-bit app is on the dock, you will see a white cross mark on the app indicating it will not work any more.
Trying to open the 32-bit with macOS Catalina will show a messages like below depending on the app:

Basically you have the following three options:
- Go to the App Store and find the replacement or upgraded app.
- Click on “Learn More…” button to go to Apple’s page explaining about 32-bit apps.
- Choose “Not Now” button to close the app.
If there are no upgrade or alternate options then you can’t use 32-bit apps with macOS Catalina.
