This page provides instructions for installing Anaconda Distribution on macOS with the command line in Terminal. ## Installation steps > [!NOTE] > > As of August 15, 2025, Anaconda has stopped building packages for Intel Mac computers (osx-64). Existing Intel (`MacOSX-x86_64`) installers are still available at [https://repo.anaconda.com/archive/](https://repo.anaconda.com/archive/), but new installers will no longer be created for Intel Macs. For more information, see [our blog on the end of Intel mac support](https://www.anaconda.com/blog/intel-mac-package-support-deprecation). 1. Download the latest `.sh` installer by opening a terminal and running the following command: ```sh theme={null} curl -O https://repo.anaconda.com/archive/Anaconda3-2026.07-1-MacOSX-arm64.sh ``` > [!NOTE] > > For instructions on downloading an older installer version, see [Using older installer versions](https://anaconda.com/docs/getting-started/advanced-install/old-os.md). 2. (Optional) Anaconda recommends verifying the integrity of the installer after downloading it. > [accordion] How do I verify my installer's integrity? > > To ensure that your downloaded installer has not been tampered with or corrupted, generate its SHA-256 hash value and compare that hash to the official hash provided in the archive. > > 1. Open Terminal and run the following command: > > ```sh Hash comparison command theme={null} > shasum -a 256 > ``` > > ```sh Example theme={null} > shasum -a 256 ~/Anaconda3-2026.07-1-MacOSX-arm64.sh > ``` > > Comments > > Replace \ with the file path to the downloaded installer file. > > 2. Note the generated SHA-256 hash value from the output. > > 3. Visit [repo.anaconda.com/archive](https://repo.anaconda.com/archive/) to find the official SHA-256 hash for your installer. > > 4. Compare the hash values. If they match, the installer is safe to use. > > > [!TIP] > > > > For more information, see [cryptographic hash verification](https://docs.conda.io/projects/conda/en/latest/user-guide/install/index.html#cryptographic-hash-verification) in the official conda documentation. 3. Install by running the following: ```sh theme={null} bash ~/Anaconda3-2026.07-1-MacOSX-arm64.sh ``` 4. Press Return to continue. You can review Anaconda's Terms of Service (TOS) at [https://anaconda.com/legal](https://anaconda.com/legal). 5. Enter `yes` to agree to the TOS. 6. Press Return to accept the default install location (`PREFIX=/Users//anaconda3`), or enter another file path to specify an alternate installation directory. The installation might take a few minutes to complete. 7. Choose `yes` when asked if you want to initialize conda. This modifies your shell configuration to initialize conda whenever you open a new shell and to recognize conda commands automatically. 8. The installer finishes and displays, "Thank you for installing Anaconda3!" 9. Close and re-open your terminal window for the installation to fully take effect, or use the following command to refresh the terminal: ```sh theme={null} source ~/.zshrc ``` > [!NOTE] > > You should see `(base)` in the command line prompt. This tells you that you're in your base conda environment. To learn more about environments, see [Environments](https://anaconda.com/docs/getting-started/working-with-conda/environments.md). ## Verify your install You can verify your installation was successful using Anaconda Navigator or your terminal application. > [tab] Anaconda Navigator > > [Anaconda Navigator](https://anaconda.com/docs/legacy/anaconda-navigator/main.md) opens automatically when installation completes successfully. > > If you need to manually open Anaconda Navigator, open **Anaconda Navigator** from your Applications folder. > [tab] Terminal > > Open your terminal application and run `conda list`. If conda has been installed correctly, a list of installed packages appears: > > ```sh Command theme={null} > conda list > ``` > > ```sh Example output theme={null} > # packages in environment at /Users//anaconda3: > # > # Name Version Build Channel > ca-certificates 2024.9.24 h06a4308_0 > certifi 2024.8.30 py312h06a4308_0 > conda 24.9.2 py312h06a4308_0 > openssl 3.0.15 h5eee18b_0 > python 3.12.7 h5148396_1 > ... > ``` ## Choose how you want to work with conda Anaconda Navigator provides a graphical user interface (GUI) to interface with conda (An open-source package and environment manager that installs, updates, and removes packages with their dependencies in isolated environments, allowing multiple versions of the same software without conflicts.), without using the command line. If you prefer working at the command line, you can interface with conda directly through Anaconda Prompt (A command-line application included with Windows installations of Anaconda Distribution and Miniconda. Find it by searching 'Anaconda Prompt' in the Windows Start menu.) (Windows) or your system's terminal (macOS and Linux) after you complete your installation. > [!NOTE] > > Anaconda Navigator is not included with Miniconda. Follow the instructions on [Installing Navigator](https://anaconda.com/docs/legacy/anaconda-navigator/install.md) to manually install Navigator onto your computer. > [card] [Get started with Navigator](https://anaconda.com/docs/legacy/anaconda-navigator/getting-started.md) > > Beginner > > Manage packages and environments with a desktop application > [card] [Work with conda](https://anaconda.com/docs/getting-started/working-with-conda/main.md) > > Use command-line tools for package and environment management ## Advanced install options For more advanced installation options, such as installing with silent mode, installing on older operating systems, or installing for multiple users, see [Advanced installation](https://anaconda.com/docs/getting-started/advanced-install/main.md). ## Troubleshooting Troubleshoot ### command not found: conda ***
Cause The `command not found: conda` error occurs when your command line interface (CLI) can't find the conda command in order to use it. This might be because: * You don't have conda properly initialized. * You have set `auto_activate_base` to `false`. * You're using a shell that conda doesn't support. * Conda is not installed or the install was incomplete or corrupted. > [!NOTE] > > These issues primarily occur on macOS/Linux computers. Anaconda Distribution and Miniconda installations on Windows include Anaconda Prompt (A command-line application included with Windows installations of Anaconda Distribution and Miniconda. Find it by searching 'Anaconda Prompt' in the Windows Start menu.), which opens with conda initialized by default.

This behavior emulates your system Python, and some users prefer to have their conda environment be inactive until they need it.

Troubleshoot ### Anaconda installer error: File or directory already exists ***
Cause When you run the installer and the target directory already contains an Anaconda Distribution installation, the installer displays the following error: ```txt theme={null} ERROR: File or directory already exists: '/Users/username/anaconda3' If you want to update an existing installation, use the -u option. ``` > [!WARNING] > > Do not use the `-u` or `-f` flags to install over an existing installation. These flags do not perform a true update. They extract the installer's packages on top of your existing files without resolving dependencies, which can leave your installation in a broken state.
***
Solution To resolve this error, either perform a clean reinstall or recover your existing installation: * **Clean reinstall**: [Uninstall Anaconda Distribution](https://anaconda.com/docs/getting-started/anaconda/uninstall.md), then run the installer again. * **Recover your installation**: If your installation is corrupted and you want to preserve your packages and environments, follow the steps in [Recovering your Anaconda installation](#recovering-your-anaconda-installation).
Troubleshoot ### This package is incompatible with this version of macOS error when running a .pkg installer on OSX ***
Cause When running the `.pkg` installer, you might encounter this error during the "Installation" step:\\ ![](https://mintcdn.com/anaconda-29683c67/r-i16GgDcvoHQ-Uq/images/getting-started/anaconda_pkg_incompatible_error_1.png?fit=max\&auto=format\&n=r-i16GgDcvoHQ-Uq\&q=85\&s=c678e0dbd97b50e8c1c06750b76d9038) This error occurs when the installation attempts to write to a directory for which it does not have write permissions.
***
Solution Manually select an appropriate install location. The following example shows how to select your user's home directory. 1. Re-run the installer and click through until you reach either the Installation Type or Destination Select page. 2. If you reach the Installation Type page first, click **Change Install Location…**. This will take you to the Destination Select page. ![](https://mintcdn.com/anaconda-29683c67/r-i16GgDcvoHQ-Uq/images/getting-started/anaconda_pkg_incompatible_error_2.png?fit=max\&auto=format\&n=r-i16GgDcvoHQ-Uq\&q=85\&s=9c7e813f2c0301f1573dea80527888f4) 3. Click **Install on a specific disk…**. 4. Click the appropriate destination drive. Then click **Choose Folder…**. ![](https://mintcdn.com/anaconda-29683c67/r-i16GgDcvoHQ-Uq/images/getting-started/anaconda_pkg_incompatible_error_3.png?fit=max\&auto=format\&n=r-i16GgDcvoHQ-Uq\&q=85\&s=a52afdc79e65c3c5bab3dc5fdd08d11f) 5. Click your user's home directory (for example, /Users/john.doe/). Then, click **Choose**. 6. In the message box, confirm the name of the install folder you chose in the previous step. Then click **Continue**. ![](https://mintcdn.com/anaconda-29683c67/r-i16GgDcvoHQ-Uq/images/getting-started/anaconda_pkg_incompatible_error_4.png?fit=max\&auto=format\&n=r-i16GgDcvoHQ-Uq\&q=85\&s=0023d8c862e48c9e3b66209cc43ad194) 7. Click **Install**, and then proceed with the rest of the installation. If you continue to receive the same error message, please open an issue [here](https://github.com/ContinuumIO/anaconda-issues/issues/new/choose/), and be sure to include the installation log output from your `install.log` file, which can be found at `/var/log/install.log`.
Troubleshoot ### Recovering your Anaconda installation ***
Cause If your Anaconda installation has become corrupted and is in a state where normal conda commands are not functioning, use the following steps to repair Anaconda and preserve your installed packages and environments.
***
Solution 1. Download a [new installer](https://repo.anaconda.com/archive/) for your operating system. > [tab] Windows > > 1. Open a terminal application, such as Command Prompt or PowerShell. > 2. If necessary, navigate to the parent directory of your Anaconda installation (by default, this is your user profile). > 3. Rename your existing installation directory so you do not overwrite it: > > ```sh Command Prompt theme={null} > move anaconda3 anaconda_old > ``` > > ```powershell PowerShell theme={null} > Move-Item anaconda3 anaconda_old > ``` > 4. Run the new Anaconda installer. When prompted for an install location, choose the same directory as your original installation. > 5. Copy your previous packages and environments to the new installation: > > ```sh theme={null} > robocopy anaconda_old anaconda3 /S > ``` > 6. Delete your old Anaconda installation directory: > > ```sh Command Prompt theme={null} > rd /s /q anaconda_old > ``` > > ```powershell PowerShell theme={null} > Remove-Item -Recurse -Force anaconda_old > ``` > [tab] macOS/Linux > > 1. Open a terminal application. > 2. If necessary, navigate to the parent directory of your Anaconda installation (by default, this is your home directory). > 3. Rename your existing installation directory so you do not overwrite it: > > ```sh theme={null} > mv anaconda3 anaconda_old > ``` > 4. Run the new Anaconda installer. When prompted for an install location, choose the same directory as your original installation: > > ```sh macOS theme={null} > bash ~/Downloads/Anaconda3-2026.07-1-MacOSX-arm64.sh > ``` > > ```sh Linux x86 theme={null} > bash ~/Downloads/Anaconda3-2026.07-1-Linux-x86_64.sh > ``` > > ```sh Linux arm64 theme={null} > bash ~/Downloads/Anaconda3-2026.07-1-Linux-aarch64.sh > ``` > 5. Copy your previous packages and environments to the new installation: > > ```sh theme={null} > rsync -a anaconda_old/ anaconda3/ > ``` > 6. Delete your old Anaconda installation directory: > > ```sh theme={null} > rm -rf anaconda_old > ``` 2. Run `conda list` to view the packages from the previous installation. 3. Run `conda info --envs` to list the environments created in the previous installation, which are now available in the new installation.
Troubleshoot ### Proxy request sent, not found ***
Cause Your company likely has security policies or a firewall in place that prevent communications with external servers or certain URLs.
***
Solution 1. First, work with your IT team to allowlist connections to the following URLs: ```txt theme={null} https://anaconda.org https://repo.anaconda.com https://repo.anaconda.cloud ``` > [!NOTE] > > Allowlisting `https://repo.anaconda.cloud` is only necessary if your company has an Anaconda organization and you require access to channels in that organization. 2. [Install](https://anaconda.com/docs/getting-started/main.md) Anaconda Distribution or Miniconda again. Once your installation is complete, you might also need to connect your company's firewall/proxy server to your conda configuration file (`.condarc`). For more information on this, see [Using Anaconda behind a firewall or proxy](https://anaconda.com/docs/anaconda-platform/getting-started-with-anaconda-platform.md#using-anaconda-behind-a-firewall-or-proxy-optional).
