32-bit app compatibility with macOS High Sierra 10.13.4
About the transition to 64-bit technology and how it affects 32-bit apps.
App is not optimized for your Mac. This app needs to be updated by its developer to improve compatibility.
State-of-the-art technology is what makes a Mac a Mac. All modern Macs include powerful 64-bit processors, and macOS runs advanced 64-bit apps, which can access dramatically more memory and enable faster system performance. The technologies that define today's Mac experience—such as Metal graphics acceleration—work only with 64-bit apps. To ensure that the apps you purchase are as advanced as the Mac you run them on, all future Mac software will eventually be required to be 64-bit.
Apple began the transition to 64-bit hardware and software technology for Mac over a decade ago, and is working with developers to transition their apps to 64-bit. At our Worldwide Developers Conference in 2017, Apple informed developers that macOS High Sierra would be the last version of macOS to run 32-bit apps without compromise.
While developers optimize their apps for 64-bit compatibility, Apple is notifying customers when they are using an app based on 32-bit technology. This is done via a one-time alert that appears when you launch a 32-bit app.
Below you will find more information about the alert and what the 64-bit transition means for you.
Why am I seeing this alert?
Starting with macOS High Sierra 10.13.4, apps that have not been updated to use 64-bit processes produce a one-time alert when opened. This gives users advance notice that they are running 32-bit software, which will not be compatible with macOS in the future.
Can I keep using my 32-bit apps?
Yes, you may continue to use 32-bit apps with your Mac today. Using 32-bit software has no adverse effects on your data or your computer.
When will the 64-bit transition be complete?
The 64-bit transition for macOS and macOS apps is still underway, so final transition dates have not yet been established. But now is a good time to check with the software developer to see if 64-bit versions of your favorite titles are available.
How do I get in touch with the app developer?
The easiest way to contact a developer is to look them up on the web. To find the name of the developer of an app, open the app, then click the app name in the menu bar and choose ”About....”
How do I check if an app is 32-bit or 64-bit?
From the Apple menu, choose About This Mac, then click the System Report button. From the system report, scroll down to Software, then select Applications. When you select an individual application, you will see a field titled ”64-bit (Intel)”. “Yes" indicates 64-bit; “No" indicates 32-bit.
