Apple M1 Chip: How To Install Homebrew Using Rosetta

Before December 2020 homebrew was not available for Apple Silicon chip.

Homebrew officially released it for the new apple silicon chip as homebrew 2.6.0

and they made some changes in the commands, In homebrew2.6.0 brew commands replacing all brew cask commands

Major changes and deprecations since 2.5.0:

• macOS Big Sur is supported (and High Sierra unsupported)

• depends_on :java

  , 

  brew switch

  , 

  brew diy

   and various other APIs have been deprecated
• All 

  brew cask

   commands have been deprecated in favour of 

  brew

   commands (with 

  --cask

  ) when necessary

• Homebrew.args

   is deprecated
• All 

  Requirement

  s are deprecated in Homebrew/core
• macOS Homebrew running natively on M1/Apple Silicon/ARM has partial functionality. We recommend installing into 

  /opt/homebrew

   and forbid installing into 

  /usr/local

   (to avoid clashing with the macOS Intel install and allow their usage side-by-side).

• brew tap-new

   will set up GitHub Actions workflows to upload to GitHub Releases. Read the blog post for more documentation.
• GitHub deprecated their API’s basic authentication

Homebrew developers recommendation (We currently recommend running Homebrew using Intel emulation with Rosetta 2.)

How to install homebrew intel based

Best method:

1. Install Rosetta or update your rosetta

2. Duplicate your terminal

goto your applications folder and locate your favourite terminal, Right-click on the terminal icon and choose Duplicate

Now you have two terminals in your Applications Folder. Rename your newly created terminal with terminal rosetta or what you like.

Now next step to make your terminal rosetta enable. Right-click on the newly created terminal and click on Get Info, it will open a new window of the application Info. Marked the option “Open using Rosetta”.

Now you have two terminals one is native and other one is Rosetta

Install HomeBrew using Rosetta Terminal

To Install HomeBrew open the Rosetta Terminal and run the following command

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

Running this command will ask you for the password, and then It will provide you with the information of what all it will install and which new directories it will create.

Once you press Enter, it will begin the installation process and will also dump the logs of the process.

Using HomeBrew

Once HomeBrew is installed, you can start using it to install your required packages into the mac.

Run the following command to get brew help

brew help

To install a package, you can run the following command

That’s all about installing and getting started with Homebrew on Apple M1 Macs.

In the upcoming articles, we will try to resolve the error in package installation through brew and cocoapods. So stay tuned.
