If you have a Mac with Apple silicon, you might be asked to install Rosetta in order to open an app.

Click Install, then enter your user name and password to allow installation to proceed. Rosetta will then be available for any of your apps that need it.

About Rosetta

Clean junk, duplicates, and useless apps to save gigabytes of disk space for something really special to you. Maximum speed no matter what—that’s what every Mac user expects. Clean your Mac’s memory and remove login items to get things running beautifully again. Files need protection. Think that downloaded file is safe? DaisyDisk is another must-have Mac app. This app lets you easily see what is cluttering up your hard drive thanks to bright and colorful blocks, so you can see what's taking up the most space. You can delete stuff directly from DaisyDisk to free up space, and it's all done in an intuitive interface that's a joy to use. A theft protection app, Prey allows you to look over your Mac, whether you are abroad or in the local market. And in case of theft, it helps you recover it. Once the app is installed, it will silently sleep and hide in the background, waiting for a go signal. Mac App Store is the simplest way to find and download apps for your Mac. To download apps from the Mac App Store, you need a Mac with OS X 10.6.6 or later. If you are a WhatsApp user on your phone you can also use the app on your Mac. After you download the app you need to open WhatsApp on your phone, go to Settings and scan the code on your desktop monitor. After this, you will see your WhatsApp messages on your desktop.

Rosetta 2 works in the background whenever you use an app built only for Mac computers with an Intel processor. It automatically translates the app for use with Apple silicon.

In most cases, you won't notice any difference in the performance of an app that needs Rosetta. But you should contact the app developer to inquire about a version that can natively use the full power and performance of Apple silicon.

Which of your apps need Rosetta?

You can use Get Info to identify apps that need Rosetta or can use Rosetta:

1. Select the app in the Finder.
2. From the File menu in the menu bar, choose Get Info.
3. View the information labeled Kind:
   • Application (Intel) means the app supports only Intel processors and needs Rosetta to work on any Mac with Apple silicon.
   • Application (Universal) means the app supports both Apple silicon and Intel processors, and uses Apple silicon by default.

The Info window for universal apps includes the setting “Open using Rosetta.” It enables email apps, web browsers, and other apps to use add-ons that haven't been updated to support Apple silicon. If an app doesn't recognize a plug-in, extension, or other add-on, quit the app, select this setting, and try again.

Learn how the Mac App Store beautifully showcases your apps and makes them even easier to find, and how Developer ID and notarization make it safer for users to install apps that you distribute yourself.

Mac App Store

The Mac App Store makes it simple for customers to discover, purchase, and download your apps, and easily keep them updated. Organized around the specific things customers love to do on Mac, along with insightful stories, curated collections, and videos, the Mac App Store beautifully showcases your apps and makes them even easier to find.

iPhone and iPad apps on Apple silicon Macs

The Mac App Store brings iPhone and iPad apps to Apple silicon Macs — so your apps can reach even more users worldwide. By default, your apps will be published automatically on the Mac App Store. Confirm that your apps gracefully handle cases where iPhone and iPad features are not available on Mac.

iPad apps that support modern technologies like keyboard input, multitasking, size classes, and SwiftUI will automatically inherit great macOS features like resizability and full screen mode.

Web Extensions

Safari Web Extensions can add custom functionality to Safari 14 using the same WebExtensions API used in other browsers, such as Chrome, Firefox, and Edge. And with a new conversion tool in Xcode 12, you can quickly bring your existing extensions to Safari and make them available on the Mac App Store.

Outside the Mac App Store

While the Mac App Store is the safest place for users to get software for their Mac, you may choose to distribute your Mac apps in other ways. Gatekeeper on macOS helps protect users from downloading and installing malicious software by checking for a Developer ID certificate. Make sure to test your apps with the latest version of macOS and sign your apps, plug-ins, or installer packages to let Gatekeeper know they’re safe to install.

You can also give users even more confidence in your apps by submitting them to Apple to be notarized.
