Apple began transitioning to 64-bit hardware and software technology for Mac over a decade ago, and all modern Macs now include powerful 64-bit processors that can run advanced 64-bit apps. These apps can access dramatically more memory, enable faster system performance, and take advantage of technologies that define today's Mac experience, such as Metal graphics acceleration.
64-bit Games
Apple has been working with developers to transition their apps, and in 2018 Apple informed them that macOS Mojave would be the last version of macOS to run 32-bit apps.
Apple's transition to 64-bit technology is now complete. Starting with macOS Catalina, 32-bit apps are no longer compatible with macOS. If you have a 32-bit app, please check with the app developer for a 64-bit version.
Opening 32-bit apps
Oct 15, 2019 OverDrive for Mac and OverDrive MP3 audiobooks are not compatible with the newest macOS version, 10.15 (Catalina), because Apple requires all apps in macOS Catalina or newer to be 64-bit,.
When you attempt to open a 32-bit app, you will see an alert that the app needs to be updated to work with this version of macOS, or that the app is not optimized for your Mac and needs to be updated.
According to an email from Apple today, 64-bit support will soon be required in new iOS apps and app updates. 1, 2015: New Apps June 1, 2015: App Updates. Dear Developer, As we announced in October, beginning February 1, 2015 new iOS apps submitted to the App Store must include 64-bit support and be built with the iOS 8 SDK. Jun 28, 2017 Apple today updated its developer news site to remind developers about 64-bit requirements for both Mac and iOS apps. Apple has required all new iOS apps and app updates submitted to the iOS App. Beginning June 1, 2015 app updates will also need to follow the same requirements. To enable 64-bit in your project, we recommend using the default Xcode build setting of “Standard architectures” to build a single binary with both 32-bit and 64-bit code. If you have any questions, visit the Apple Developer Forums. Starting in January 2018, all new apps submitted to the Mac App Store must be 64-bit capable and, as of June 2018, both new apps and app updates must be 64-bit capable. Submissions not matching.
macOS Catalina
macOS Mojave and macOS High Sierra
If you haven't upgraded to macOS Catalina, you can still open and use the app, but you should check with the app developer for a 64-bit version that also works with the latest macOS.
How to find 32-bit apps on your Mac
System Information can find 32-bit apps that are installed on your Mac:
- Choose Apple menu > About This Mac, then click the System Report button.
- Select Legacy Software in the sidebar. All legacy software is 32-bit.
- If you don't see Legacy Software in the sidebar, select Applications in the sidebar, then check the list of apps on the right. The column labeled ”64-Bit (Intel)” shows ”No” for apps that are 32-bit.
When upgrading to macOS Catalina, the installer shows a list of recently used apps that are 32-bit. You can review this list before choosing whether to cancel or continue the installation:
macOS Catalina also shows a prohibitory symbol over the icon of each 32-bit app in the Finder, letting you know that the app will not open.
How to contact the app developer
The developer (or vendor) is the person or company that made the app. The easiest way to find contact information for an app's developer is to search the web for their name or the name of their app. Learn more about contacting third-party vendors.
To find the name of the developer:
- Select the app in the Finder.
- Choose File > Get Info from the menu bar.
- Look for copyright information in the Info window. For example, Apple is the developer of this app:
With iOS 9, developers can cutoff younger devices in a way that was not previously possible. Although iOS 9 runs on every device that runs iOS 8, app developers are free to specify more restrictive compatibility requirements.
In fact, with iOS 9, developers can choose to make their apps exclude any non-64 bit architecture. This means all iPod touch models, all iPhones before the iPhone 5s and all iPads before the iPad Air will not be able to install apps where developers have required 64-bit CPUs.
Apple started using 64-bit CPUs with the A7 in the iPhone 5s, a 2013 device. Developers often complain about supporting older hardware platforms (such as the A5 which is very slow by modern standards) and so this option will offer a quick-and-easy way to simplify development.
If a developer enables this option, customers browsing the App Store with older devices will simply not see that app in the Store and won’t be able to download or install it.

The limit has little to do with the 64-bit support itself — binaries can be built that support both platforms. However, the processors are simply much more powerful than their predecessors which puts a lot of strain on developers to support both platforms well. Apple showed how GPU performance increased dramatically in the last two years with the 64-bit processors (above).
It’s a highly convenient cutoff for developers to make it easy for them to drop compatibility for older devices. Obviously, customers with non-64 bit iPads and iPhones may be upset as developers may actively cut off support in their apps for these hardware variants due to the convenience, not necessarily for technical reasons.

As developers like making their lives easier, with iOS 9, users may find their devices become obsolete faster as more apps no longer support them.
