The following are the system requirements for installing the JDK and the JRE on macOS:

• Any Intel-based computer running macOS.

• Administrator privileges.

  You cannot install Java for a single user. Installing the JDK and JRE on macOS is performed on a systemwide basis for all users. Administrator privileges are required to install the JDK and JRE on macOS.

• When you install the JDK, it also installs the JRE. However, the system will not replace the current JRE with a lower version.

  To determine the current JRE version installed on your system, see Determining the JRE Version Installed on macOS. To install an earlier version of the JRE, you must first uninstall the current version. See Uninstalling the JRE on macOS.

• When you install the JRE, you can install only one JRE on your system at a time. The system will not install a JRE that has an earlier version than the current version.

  To determine the current JRE version installed on your system, see Determining the JRE Version Installed on macOS. To install an earlier version of the JRE, you must first uninstall the current version. See Uninstalling the JRE on macOS.

  Note:

  Installing a JRE from Oracle will not update java -version symlinks or add java to your path. To do this, you must install the JDK.

Press and hold the power button on your Mac to completely shut it off. Hard discs and fans need to stop spinning, and the screen needs to go dark. Power on your Mac. Immediately after you hear the startup sound, press and hold the Command + Option + P + R keys. Keep holding them down until you hear the startup sound again. While the issue with Big Sur was live on 12 November Apple had the following text on the site indicating that there was a problem: 'Users may not be able to download macOS Software Updates on Mac. Hence on my Mac running Lion (10.7.5) I use the same command with '-v 1.6'. This is crucial because I need Java 6 and Oracle doesnt provide one for Mac OS - only Java 7, and this allows me to use the installed JAva 6 even though Java 7 is installed. – Rhubarb May 20 '13 at 11:43.

Using Anaconda in a commercial setting? You may need to use Anaconda Commercial Edition. If you have already purchased Commercial Edition, please proceed to the Authenticating Commercial Edition section after completing your installation here.

Haven’t purchased Commercial Edition yet? Visit https://anaconda.cloud/register to get started.

You can install Anaconda using either the graphical installer (“wizard”) or thecommand line (“manual”) instructions below. If you are unsure, choose the graphical install.

macOS graphical install¶

1. Download the graphical macOS installer for your version of Python.

2. RECOMMENDED: Verify data integrity with SHA-256.For more information on hashes, see What about cryptographic hash verification?

3. Double-click the downloaded file and click continue to start the installation.

4. Answer the prompts on the Introduction, Read Me, and License screens.

5. Click the Install button to install Anaconda in your ~/opt directory (recommended):

6. OR, click the Change Install Location button to install in another location (not recommended).

   On the Destination Select screen, select Install for me only.

   Note

   If you get the error message “You cannot install Anaconda in this location,” reselect Install for me only.

7. Click the continue button.

8. Optional: To install PyCharm for Anaconda, click on the link to https://www.anaconda.com/pycharm.

   Or to install Anaconda without PyCharm, click the Continue button.

9. A successful installation displays the following screen:

Using the command-line install¶

Use this method if you prefer to use a terminal window.

1. In your browser, download the command-line version of themacOS installer for your system.

2. RECOMMENDED: Verify data integrity with SHA-256.For more information on hash verification, see cryptographic hash validation.

   • Open a terminal and run the following:

   Note

   Replace /path/filename with your installation’s path and filename.

3. Install for Python 3.7 or 2.7:

   • For Python 3.7 enter the following:

   • For Python 2.7, open the Terminal.app or iTerm2 terminal application and then enter the following:

   Note

   Include the bash command regardless of whether or not you are using the Bash shell.

   Note

   Replace ~/Downloads with your actual path and Anaconda3-2020.02-MacOSX-x86_64.sh with actual name of the file you downloaded.

4. The installer prompts “In order to continue the installation process, please review the license agreement.”Click Enter to view the license terms.

5. Scroll to the bottom of the license terms and enter yes to agree to them.

6. The installer prompts you to Press Enter to confirm the location, Press CTRL-C to cancel the installationor specify an alternate installation directory. If you confirm the default location,it will display PREFIX=/home/<user>/anaconda<2or3> and continue the installation.

   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.
