Introduction: What is Rosetta and why do you need it?
Apple has been transitioning its Mac lineup to use its own custom-designed processors based on the Arm architecture. These processors, known as Apple silicon, offer better performance and efficiency than the Intel processors that were used in previous Mac models. However, this also means that some apps that were developed for Intel Macs may not work on Apple silicon Macs without some help.
That's where Rosetta comes in. Rosetta is a translation layer that allows a Mac with Apple silicon to run apps that were built only for Intel Macs. It works automatically in the background whenever you use an app that needs it. It translates the app's code from Intel x86_64 to Arm64, which is the architecture used by Apple silicon. In most cases, you won't notice any difference in the performance or functionality of an app that runs through Rosetta.
However, not every app needs Rosetta. Some apps have been updated to run natively on Apple silicon, which means they can take advantage of the full power and features of the new processors. These apps are called Universal apps, because they can run on both Apple silicon and Intel Macs. Other apps may not need any translation at all, because they are written in a way that is compatible with both architectures.
How to check if an app needs Rosetta or not?
To identify apps that need Rosetta or can use Rosetta, you can follow these steps:
[If you need to install Rosetta on your Mac - Apple Support](^1^)
[How to install Rosetta on Mac Tom's Guide](^2^)
[If you need to install Rosetta on your Mac Apple Support (UK)](^3^)
Select an app in the Finder.
From the File menu in the menu bar, choose Get Info.
See the information labeled Kind:
Application (Intel) means the app supports only Intel processors and needs Rosetta to work on a Mac with Apple silicon.
Application (Universal) means the app supports both Apple silicon and Intel processors, and uses Apple silicon by default. Universal apps don't need Rosetta.
For apps labeled Application (Universal), the Info window also includes the setting "Open using Rosetta". This setting allows a Universal app to use plug-ins, extensions, or other add-ons that haven't been updated to support Apple silicon. If a Universal app doesn't recognize an add-on that you installed for the app, you can quit the app, select this setting, and try again.

Installing Rosetta on your MacBook Air is very easy and fast. You don't need to download anything manually or go through any complicated steps. Rosetta will be installed automatically the first time you try to open an app that needs it. Here's how it works:
Double-click an app that needs Rosetta to run.
A message will appear asking if you want to install Rosetta. Click Install.
Enter your administrator password if prompted.
Wait for a few seconds while Rosetta is downloaded and installed.
The app will launch and run normally.
That's it! You only need to do this once for the first app that needs Rosetta. After that, any other app that needs Rosetta will run without asking you to install it again. You can also uninstall Rosetta at any time if you don't need it anymore. To do that, follow these steps:
Open the Terminal app, which you can find in the Utilities folder of the Applications folder.
Type the following command and press Enter: sudo softwareupdate --remove-rosetta
Enter your administrator password if prompted.
Wait for a few seconds while Rosetta is removed.
How to use Rosetta to run Intel-based apps on your MacBook Air?
Using Rosetta to run Intel-based apps on your MacBook Air is very simple and seamless. You don't need to do anything special or different from how you normally use your apps. Rosetta works in the background and translates the app's code on the fly, without affecting your user experience. Here are some tips for using Rosetta effectively:
Keep your apps updated. Developers may release updates that improve the compatibility or performance of their apps on Apple silicon Macs. Check for updates regularly and install them when available.
Check the app's preferences or settings. Some apps may have options that let you optimize their behavior or performance for Apple silicon Macs. For example, some apps may let you choose between different graphics modes or rendering engines.
Report any issues or feedback to the app's developer. If you encounter any problems or bugs with an app that runs through Rosetta, let the developer know. They may be able to fix them in future updates or provide you with a workaround. You can usually find the developer's contact information on their website or in the app's About menu.
Benefits of Rosetta for MacBook Air
Rosetta is a powerful and convenient feature that lets you enjoy the benefits of Apple silicon Macs without sacrificing compatibility with Intel-based apps. Here are some of the advantages of using Rosetta on your MacBook Air:
Compatibility: Run apps that are not yet updated for Apple silicon
Rosetta allows you to run most apps that are designed only for Intel Macs on your MacBook Air with Apple silicon. This means you don't have to wait for developers to update their apps or switch to different apps that support Apple silicon. You can continue using your favorite apps as usual, even if they haven't been updated yet.
Performance: Enjoy fast and smooth translation of Intel-based apps
Rosetta is designed to translate Intel-based apps as quickly and efficiently as possible, without compromising their performance or functionality. In many cases, you won't notice any difference in speed or quality between an app that runs natively on Apple silicon and one that runs through Rosetta. In fact, some apps may even run faster or better on Apple silicon Macs than on Intel Macs, thanks to the superior performance and efficiency of the new processors.
Convenience: No need to interact with Rosetta, it works automatically in the background
Rosetta is very easy to use and requires minimal user intervention. You don't need to launch it separately or configure any settings. It works automatically whenever you open an app that needs it, and it stays out of your way while you use the app. You don't have to worry about managing or updating Rosetta, as it is part of macOS and receives updates along with the system software.
Common Issues with Rosetta for MacBook Air
Rosetta is a remarkable technology that enables a smooth transition from Intel Macs to Apple silicon Macs, but it is not perfect. There are some limitations and challenges that you may encounter when using Rosetta on your MacBook Air. Here are some of the common issues and how to deal with them:
Limitations: Rosetta cannot translate kernel extensions, virtualization apps, or some games
Rosetta allows you to run most apps that are designed only for Intel Macs on your MacBook Air with Apple silicon. It works automatically in the background and translates the app's code on the fly, without affecting your user experience.
Rosetta has some limitations and challenges, such as not being able to translate kernel extensions, virtualization apps, or some games. It may also cause some problems with installation errors, app crashes, or missing add-ons.
Rosetta is not the only solution for running Intel-based apps on your MacBook Air with Apple silicon. You can also try some alternatives, such as Boot Camp, virtual machines, or emulators. However, these alternatives have their own drawbacks and requirements.
We hope this article has helped you understand how to use Rosetta on your MacBook Air with Apple silicon. If you have any questions, feedback, or suggestions, please feel free to share them in the comments section below. We would love to hear from you!
Here are some of the frequently asked questions about Rosetta for MacBook Air:
Q: How do I know if an app is running through Rosetta or natively on Apple silicon?
A: You can use the Activity Monitor app, which you can find in the Utilities folder of the Applications folder. Open the Activity Monitor app and click the CPU tab. Look for the column labeled Architecture. If an app is running through Rosetta, it will show Intel. If an app is running natively on Apple silicon, it will show Apple.
Q: How do I update Rosetta?
A: Rosetta is part of macOS and receives updates along with the system software. To check for updates, go to System Preferences > Software Update and click Update Now if there are any available updates.
Q: How do I uninstall an app that runs through Rosetta?
A: You can uninstall an app that runs through Rosetta the same way you uninstall any other app on your Mac. You can drag the app to the Trash or use an uninstaller tool if the app provides one.
