With the release of macOS Catalina, 32-bit app support is no longer available, which means many of your older apps will no longer work if they haven't been updated to 64-bit.
32-bit vs. 64-bit
32-bit apps date back to a time when there were 32-bit processors and 32-bit operating systems, but are now outdated. Apple has long since transitioned to 64-bit processors and macOS has been 64-bit since the launch of Snow Leopard in 2009.
Compared to 32-bit apps, 64-bit apps can take advantage of more memory and offer faster system performance. Apple technologies like Metal only work with 64-bit apps, and for Apple to ensure that Mac apps include all of the latest advancements and optimizations, support for 32-bit needs to end. In the simplest terms, 32-bit apps are inefficient.
32-bit apps can run on a 64-bit system as they've been doing for years, but Apple wants to get rid of outdated apps to make sure everything that runs on the Mac is properly optimized and isn't an unnecessary drain on system resources.
Previous Warnings
Apple started warning Mac users about plans to end support for 32-bit apps back with macOS High Sierra. In High Sierra, users started getting warnings about a 32-bit app's future incompatibility with macOS.
A similar message was available in macOS Mojave, and if you opened up a 32-bit app while running Mojave, you saw an alert letting you know a specific app wouldn't work with future versions of macOS unless it was updated.
Alerts re-appeared every 30 days when launching an app, with Apple aiming to make sure customers would not be caught unaware when a 32-bit app stopped working in the future, so you should already know if one of your frequently used apps hasn't been upgraded to 64-bit.
Upon updating to macOS Catalina, you'll be shown a list of 32-bit apps that no longer work on your system.
How to Check if an App is 32-Bit or 64-Bit in macOS Mojave
To determine whether an app is 64-bit or 32-bit and to see if there are 32-bit apps installed on your machine before upgrading to macOS Catalina, follow these steps:
- Click the Apple symbol () in the menu bar on your Mac's desktop.
- Click on About This Mac.
- Choose 'System Report' at the bottom of the window.
- Scroll down to the Software list on the sidebar.
- Select Legacy Software.'
Anything in the list of Legacy Software applications is a 32-bit app and will not work when upgrading to macOS Catalina.
