If you need to install Rosetta(Intel processor) on your Mac with Apple silicon M1 ARM Chip

Rosetta 2 enables a Mac with Apple silicon to use apps built for a Mac with an Intel processor.

How to install Rosetta

Rosetta 2 is available only for Mac computers with Apple silicon.

Make sure that your Mac is connected to the internet.
Open any app that needs Rosetta. If the app opens, Rosetta is already installed and working.
If Rosetta is not installed, you're automatically asked to install it.
Click Install, then enter your user name and password to allow installation to proceed. If you click Not Now, you will be asked again the next time you open an app that needs Rosetta.

How to use Rosetta

Rosetta is not an app that you open or interact with. Rosetta works automatically in the background whenever you use an app that was built only for Mac computers with an Intel processor. It translates the app for use with Apple silicon. Simply open your app and use it like you normally would.

In most cases, you won't notice any difference in the performance of an app that uses 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.

Does your app need Rosetta?

Select the app's icon in the Finder.
From the File menu in the Finder menu bar, choose Get Info.
In the Info window that opens, look for the information labeled Kind. If the kind is Application (Intel), the app needs Rosetta to work on a Mac with Apple silicon. If the kind is Application (Universal), the app doesn't need Rosetta, because it supports both Apple silicon and Intel processors.

Some universal apps (apps that don't need Rosetta) include the setting “Open using Rosetta.” This setting enables a universal app such as a web browser to use plug-ins, extensions, or other add-ons that do need Rosetta, because they 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.

Mac computers with Apple silicon

Starting with certain models introduced in late 2020, Apple began the transition from Intel processors to Apple silicon in Mac computers.

Mac computers with Apple silicon:

MacBook Pro introduced in 2021 or later, plus MacBook Pro (13-inch, M1, 2020)
MacBook Air introduced in 2022 or later, plus MacBook Air (M1, 2020)
iMac introduced in 2021 or later
Mac mini introduced in 2020 or later
Mac Studio introduced in 2022 or later
Mac Pro introduced in 2023

On Mac computers with Apple silicon, About This Mac shows an item labeled Chip, followed by the name of the chip:

To open About This Mac, choose Apple menu  > About This Mac.

On Mac computers with an Intel processor, About This Mac shows an item labeled Processor, followed by the name of an Intel processor. A Mac with an Intel processor is also known as an Intel-based Mac.
