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.
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.
The Macintosh, or Mac, is a series of several lines of personal computers, manufactured by Apple Inc. The first Macintosh was introduced on January 24, 1984, by Steve Jobs (see the lower photo) and it was the first commercially successful personal computer to feature two old known then, but still unpopular features—the mouse and the graphical user interface, rather than the command-line. MacOS is the second major series of Macintosh operating systems.The first is colloquially called the classic Mac OS, introduced in 1984, the final release of which was Mac OS 9 in 1999. The first desktop version, Mac OS X 10.0, was released in March 2001, with its first update, 10.1, arriving later that year.After this, Apple began naming its releases after big cats, which lasted until OS X 10.

Mar 31, 2015 With automatic software updates in the Mac App Store, introduced in OS X Mavericks, Apple has made it easier than ever to keep your Mac up to date with the latest versions of apps and system files. Apple helpfully displays recently installed updates in the Mac App Store, but detailed information about software updates, not to mention logs of third party software obtained outside of the Mac.
Opening 32-bit apps
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.
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 perform tasks of any kind in Mac OS X Lion, you use one of the applications installed on your Mac. The application you use depends on the task you want to perform. For example, if you want to surf the World Wide Web, you would use a web browser application, such as the Safari program that comes with Mac OS X.
Before you can use an application, however, you must first tell Mac OS X Lion which application you want to run. Mac OS X Lion launches the application and displays it on the desktop. You can then use the application’s tools to perform your tasks.
To start an Application:
