Installing Homebrew and Anaconda on a Mac

Install Homebrew

Run the following command on your terminal to install Homebrew. Homebrew is a package manager for Macs and is used to install useful development tools and software.

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

Install Anaconda through Homebrew

1. Run brew install --cask anaconda to install Anaconda
2. Run echo 'export PATH=/usr/local/anaconda3/bin:$PATH' >> ~/.zshrc from your terminal
3. Also run echo 'export PATH=/opt/homebrew/anaconda3/bin:$PATH' >> ~/.zshrc from your terminal
4. Run source ~/.zshrc from your terminal
5. Type conda to ensure that anaconda linked correctly.

If you use bash instead of zsh, replace steps 2 and 3 from above with the following:

• echo 'export PATH=/usr/local/anaconda3/bin:$PATH' >> ~/.bash_profile
• echo 'export PATH=/opt/homebrew/anaconda3/bin:$PATH' >> ~/.bash_profile
• source ~/.bash_profile

If you've already installed anaconda from the installation file from anaconda.org

If you installed Anaconda for only this user, run the following:

• echo 'export PATH=/Users/$USER/anaconda3/bin:$PATH' >> ~/.zshrc
• echo 'export PATH=/opt/homebrew/anaconda3/bin:$PATH' >> ~/.zshrc
• source ~/.zshrc

If you installed Anaconda for all users on your computer, then run the following:

• echo 'export PATH=/opt/anaconda3/bin:$PATH' >> ~/.zshrc
• source ~/.zshrc

I don't think conda init zsh will work. It needs to be initialized from the Homebrew location. In the link from @AlifUnseen I found what seems to be the correct instructions:

For people using homebrew to install anaconda (brew install --cask anaconda) instead of manually adding conda to PATH run /(your conda installation path)/bin/conda init zsh which on Apple silicon (M1/M2) is /opt/homebrew/anaconda3/bin/conda init zsh. This adds conda to your PATH in .zshrc and makes sure that you can now use conda and activate conda environments.

Then you can run source ~/zshrc and use conda in your shell.

super helpful, thanks a lot 🙌

super helpful, thanks a lot

While command uname -m returns arm64, brew install --cask anaconda still downloads x84_64 version of Conda instead of arm64 version. Anyone running into this issue?

thanks

thank you!

Great! Thanks :)
