Mac OS X comes with Python 2.7 out of the box.

Python for Mac OS X. Python comes pre-installed on Mac OS X so it is easy to start using. However, to take advantage of the latest versions of Python, you will need to download and install newer versions alongside the system ones. The easiest way to do that is to install one of the binary installers for OS X from the Python Download page.

You do not need to install or configure anything else to use Python 2. Theseinstructions document the installation of Python 3.

The version of Python that ships with OS X is great for learning, but it’s notgood for development. The version shipped with OS X may be out of date from theofficial current Python release,which is considered the stable production version.

Doing it Right¶

Let’s install a real version of Python.

Before installing Python, you’ll need to install GCC. GCC can be obtainedby downloading Xcode, the smallerCommand Line Tools (must have anApple account) or the even smaller OSX-GCC-Installerpackage.

Note

If you already have Xcode installed, do not install OSX-GCC-Installer.In combination, the software can cause issues that are difficult todiagnose.

Note

If you perform a fresh install of Xcode, you will also need to add thecommandline tools by running xcode-select--install on the terminal.

While OS X comes with a large number of Unix utilities, those familiar withLinux systems will notice one key component missing: a package manager.Homebrew fills this void.

To install Homebrew, open Terminal oryour favorite OS X terminal emulator and run

The script will explain what changes it will make and prompt you before theinstallation begins.Once you’ve installed Homebrew, insert the Homebrew directory at the topof your PATH environment variable. You can do this by adding the followingline at the bottom of your ~/.profile file

If you have OS X 10.12 (Sierra) or older use this line instead

Now, we can install Python 3:

This will take a minute or two.

Pip¶

Homebrew installs pip pointing to the Homebrew’d Python 3 for you.

Working with Python 3¶

At this point, you have the system Python 2.7 available, potentially theHomebrew version of Python 2 installed, and the Homebrewversion of Python 3 as well.

will launch the Homebrew-installed Python 2 interpreter (if any).

will launch the Homebrew-installed Python 3 interpreter.

If the Homebrew version of Python 2 is installed then pip2 will point to Python 2.If the Homebrew version of Python 3 is installed then pip will point to Python 3.

The rest of the guide will assume that python references Python 3.

Pipenv & Virtual Environments¶

The next step is to install Pipenv, so you can install dependencies and manage virtual environments.

A Virtual Environment is a tool to keep the dependencies required by different projectsin separate places, by creating virtual Python environments for them. It solves the“Project X depends on version 1.x but, Project Y needs 4.x” dilemma, and keepsyour global site-packages directory clean and manageable.

For example, you can work on a project which requires Django 1.10 while alsomaintaining a project which requires Django 1.8.

So, onward! To the Pipenv & Virtual Environments docs!

What to know before you install

README FIRST for Docker Toolbox and Docker Machine users

If you are already running Docker on your machine, first readDocker Desktop for Mac vs. Docker Toolbox to understand theimpact of this installation on your existing setup, how to set your environmentfor Docker Desktop on Mac, and how the two products can coexist.

Relationship to Docker Machine: Installing Docker Desktop on Mac does not affect machines you created with Docker Machine. You have the option to copy containers and images from your local default machine (if one exists) to the Docker Desktop HyperKit VM. Whenyou are running Docker Desktop, you do not need Docker Machine nodes running locally (or anywhere else). With Docker Desktop, you have a new, nativevirtualization system running (HyperKit) which takes the place of theVirtualBox system. To learn more, see Docker Desktop for Mac vs. Docker Toolbox.

System requirements

Your Mac must meet the following requirements to successfully install Docker Desktop:

• Mac hardware must be a 2010 or a newer model, with Intel’s hardware support for memory management unit (MMU) virtualization, including Extended Page Tables (EPT) and Unrestricted Mode. You can check to see if your machine has this support by running the following command in a terminal: sysctl kern.hv_support

  If your Mac supports the Hypervisor framework, the command prints kern.hv_support: 1.

• macOS must be version 10.13 or newer. That is, Catalina, Mojave, or High Sierra. We recommend upgrading to the latest version of macOS.

  If you experience any issues after upgrading your macOS to version 10.15, you must install the latest version of Docker Desktop to be compatible with this version of macOS.

  Note: Docker supports Docker Desktop on the most recent versions of macOS. That is, the current release of macOS and the previous two releases. Docker Desktop currently supports macOS Catalina, macOS Mojave, and macOS High Sierra.

  Alien isolation mac torrent games. As new major versions of macOS are made generally available, Docker stops supporting the oldest version and support the newest version of macOS (in addition to the previous two releases).

• At least 4 GB of RAM.

• VirtualBox prior to version 4.3.30 must not be installed as it is not compatible with Docker Desktop.

What’s included in the installer

The Docker Desktop installation includes Docker Engine, Docker CLI client, Docker Compose, Notary, Kubernetes, and Credential Helper.

Install and run Docker Desktop on Mac

1. Double-click Docker.dmg to open the installer, then drag the Docker icon to the Applications folder.

2. Double-click Docker.app in the Applications folder to start Docker. (In the example below, the Applications folder is in “grid” view mode.)

   You are prompted to authorize Docker.app with your system password after you launch it. Privileged access is needed to install networking components and links to the Docker apps.

   The Docker menu in the top status bar indicates that Docker Desktop is running, and accessible from a terminal.

   If you just installed the app, you also get a message with suggested next steps and a link to the documentation. Click the Docker menu () in the status bar to dismiss this pop-up notification.

3. Click the Docker menu () to seePreferences and other options.

4. Select About Docker to verify that you have the latest version.

Congratulations! You are now successfully running Docker Desktop.

Uninstall Docker Desktop

To unistall Docker Desktop from your Mac:

1. From the Docker menu, select Troubleshoot and then select Uninstall.
2. Click Uninstall to confirm your selection.

Note: Uninstalling Docker Desktop will destroy Docker containers and images local to the machine and remove the files generated by the application.

Switch between Stable and Edge versions

Docker Desktop allows you to switch between Stable and Edge releases. However, you can only have one version of Docker Desktop installed at a time. Switching between Stable and Edge versions can destabilize your development environment, particularly in cases where you switch from a newer (Edge) channel to an older (Stable) channel.

For example, containers created with a newer Edge version of Docker Desktop maynot work after you switch back to Stable because they may have been createdusing Edge features that aren’t in Stable yet. Keep this in mind asyou create and work with Edge containers, perhaps in the spirit of a playgroundspace where you are prepared to troubleshoot or start over.

To safely switch between Edge and Stable versions, ensure you save images and export the containers you need, then uninstall the current version before installing another. For more information, see the section Save and Restore data below.

Save and restore data

You can use the following procedure to save and restore images and container data. For example, if you want to switch between Edge and Stable, or to reset your VM disk:

1. Use docker save -o images.tar image1 [image2 ..] to save any images you want to keep. See save in the Docker Engine command line reference.

2. Use docker export -o myContainner1.tar container1 to export containers you want to keep. See export in the Docker Engine command line reference.

3. Uninstall the current version of Docker Desktop and install a different version (Stable or Edge), or reset your VM disk.

4. Use docker load -i images.tar to reload previously saved images. See load in the Docker Engine.

5. Use docker import -i myContainer1.tar to create a filesystem image corresponding to the previously exported containers. See import in the Docker Engine.
