To ensure the authenticity of its software updates, Apple digitally signs all updates and offers them exclusively through the App Store or Apple Support Downloads site. Always get Apple software updates from one of these sources, and always check these sources to make sure that you have the latest software version.

Some software updates are automatically verified

When you download and install an update from Apple, Apple's digital signature is automatically verified before installation.

Manually downloaded software updates can be verified manually

If you manually download an Apple software update, you can confirm that the update is authentic and complete by verifying the digital signature before installation.

  3. Install for Python 3.7 or 2.7:

    • For Python 3.7 enter the following:

    Note

    Unlike the graphical install, installing the shell file will place it in ~/anaconda<2 or 3> by default,not ~/opt. This is due to limitations with installing .pkg files on macOS Catalina.

    Installation may take a few minutes to complete.

    Note

    We recommend you accept the default install location. Do not choose the path as /usr for theAnaconda/Miniconda installation.

  7. The installer prompts “Do you wish the installer to initialize Anaconda3by running conda init?” We recommend “yes”.

    Note

    If you enter “no”, then conda will not modify your shell scripts at all.In order to initialize after the installation process is done, first runsource<pathtoconda>/bin/activate and then run condainit.

    Note

    If you are on macOS Catalina, the new default shell is zsh.You will instead need to run source<pathtoconda>/bin/activatefollowed by condainitzsh.

  8. The installer displays “Thank you for installing Anaconda!”

  9. Optional: The installer describes the partnership between Anaconda and JetBrains andprovides a link to install PyCharm for Anaconda athttps://www.anaconda.com/pycharm.

  10. Close and open your terminal window for the Anaconda installation to take effect.

  11. To control whether or not each shell session has the base environmentactivated or not, run condaconfig--setauto_activate_baseFalseorTrue. To run conda from anywhere without having the base environmentactivated by default, use condaconfig--setauto_activate_baseFalse.This only works if you have run condainit first.

    Note

    condainit is available in conda versions 4.6.12 and later.

  12. Verify your installation.
