Introduction
The command line interface is a non-graphical way to interact with your computer. Instead of clicking buttons with your mouse, you’ll type commands as text and receive text-based feedback. The command line, also known as a shell, lets you automate many tasks you do on your computer daily, and is an essential tool for software developers.
16 hours ago The command uses curl to download the Homebrew installation script from Homebrew’s Git repository on GitHub. Let’s walk through the flags that are associated with the curl command: The - f or -fail flag tells the Terminal window to give no HTML document output on server errors.
While the command line interface on macOS has a lot of the functionality you’d find in Linux and other Unix systems, it does not ship with a good package manager. A package manager is a collection of software tools that work to automate software installations, configurations, and upgrades. Package managers keep the software they install in a central location and can maintain all software packages on the system in formats that are commonly used.

After installing brew, install libgdiplus by executing the following commands at a Terminal (command) prompt: brew update brew install mono-libgdiplus Install with an installer. MacOS has standalone installers that can be used to install the.NET Core.

Homebrew is a package manager for macOS which lets you install free and open-source software using your terminal. You’ll use Homebrew to install developer tools like Python, Ruby, Node.js, and more.
In this tutorial you’ll install and use Homebrew on your Mac.
Prerequisites
You will need a macOS computer running High Sierra or higher with administrative access and an internet connection.
Step 1 — Using the macOS Terminal
To access the command line interface on your Mac, you’ll use the Terminal application provided by macOS. Like any other application, you can find it by going into Finder, navigating to the
Applications
folder, and then into the Utilities
folder. From here, double-click the Terminal application to open it up. Alternatively, you can use Spotlight by holding down the COMMAND
key and pressing SPACE
to find Terminal by typing it out in the box that appears.To get more comfortable using the command line, take a look at An Introduction to the Linux Terminal. The command line interface on macOS is very similar, and the concepts in that tutorial are directly applicable.
Now that you have the Terminal running, let’s install some additional tools that Homebrew needs.
Step 2 — Installing Xcode’s Command Line Tools
Xcode is an integrated development environment (IDE) that is comprised of software development tools for macOS. You won’t need Xcode to use Homebrew, but some of the software and components you’ll want to install will rely on Xcode’s Command Line Tools package.
Execute the following command in the Terminal to download and install these components:
You’ll be prompted to start the installation, and then prompted again to accept a software license. Then the tools will download and install automatically.
You can now install Homebrew.
Step 3 — Installing and Setting Up Homebrew
To install Homebrew, you’ll download an installation script and then execute the script.
First, download the script to your local machine by typing the following command in your Terminal window:
The command uses
curl
to download the Homebrew installation script from Homebrew’s Git repository on GitHub. Let’s walk through the flags that are associated with the
curl
command:- The -
f
or--fail
flag tells the Terminal window to give no HTML document output on server errors. - The
-s
or--silent
flag mutescurl
so that it does not show the progress meter, and combined with the-S
or--show-error
flag it will ensure thatcurl
shows an error message if it fails. - The
-L
or--location
flag will tellcurl
to handle redirects. If the server reports that the requested page has moved to a different location, it’ll automatically execute the request again using the new location. - The
-o
switch specifies a local filename for the file.
Before running a script you’ve download from the Internet, you should review its contents so you know what the script will do. Use the
less
command to look at the installation script:Once you’re comfortable with the contents of the script, execute the script with the
bash
command:The installation script will explain what it will do and will prompt you to confirm that you want to do it. This lets you know exactly what Homebrew is going to do to your system before you let it proceed. It also ensures you have the prerequisites in place before it continues.
You’ll be prompted to enter your password during the process. However, when you type your password, your keystrokes will not display in the Terminal window. This is a security measure and is something you’ll see often when prompted for passwords on the command line. Even though you don’t see them, your keystrokes are being recorded by the system, so press the
RETURN
key once you’ve entered your password. Press the letter
y
for “yes” whenever you are prompted to confirm the installation.Once the installation process is complete, you will want to put the directory Homebrew uses to store its executables at the front of the
PATH
environment variable. This ensures that Homebrew installations will be called over the tools that macOS includes. The file you’ll modify depends on which shell you’re using. If you’re using Bash, you’ll use the file
~/.bash_profile
:However, if you’re using ZSH, you’ll open the file
~/.zshrc
.Once the file opens up in the Terminal window, add the following lines to the end of the file:
The first line is a comment that will help you remember what this does if you open this file in the future.
To save your changes, hold down the
CTRL
key and the letter O
, and when prompted, press the RETURN
key. Then exit the editor by holding the CTRL
key and pressing X
. This will return you to your Terminal prompt.To activate these changes, close and reopen your Terminal app. Alternatively, use the
source
command to load the file you modified.If you modified
.bash_profile
, execute this command:If you modified
.zshrc
, execute this command:Once you have done this, the changes you have made to the
PATH
environment variable will take effect. They’ll be set correctly when you log in again in the future, as the configuration file for your shell is executed automatically when you open the Terminal app.Now let’s verify that Homebrew is set up correctly. Execute this command:
If no updates are required at this time, you’ll see this in your Terminal:
Otherwise, you may get a warning to run another command such as
brew update
to ensure that your installation of Homebrew is up to date. Follow any on-screen instructions to fix your environment before moving on.Step 4 — Installing, Upgrading, and Removing Packages
Now that Homebrew is installed, use it to download a package. The
tree
command lets you see a graphical directory tree and is available via Homebrew.Install
tree
with the brew install
command:Homebrew will update its list of packages and then download and install the
tree
command:Homebrew installs files to
/usr/local
by default, so they won’t interfere with future macOS updates. Verify that tree
is installed by displaying the command’s location with the which
command:The output shows that
tree
is located in /usr/local/bin
:Run the
tree
command to see the version:The version prints to the screen, indicating it’s installed:
Occasionally, you’ll want to upgrade an existing package. Use the
brew upgrade
command, followed by the package name:You can run
brew upgrade
with no additional arguments to upgrade all programs and packages Homebrew manages.When you install a new version, Homebrew keeps the older version around. After a while, you might want to reclaim disk space by removing these older copies. Run
brew cleanup
to remove all old versions of your Homebrew-managed software.To remove a package you’re no longer using, use
brew uninstall
. To uninstall the tree
command, execute this command:The output shows that the package was removed:
You can use Homebrew to install desktop applications too.
Step 5 — Installing Desktop Applications
You’re not restricted to using Homebrew for command-line tools. Homebrew Cask lets you install desktop applications. This feature is included with Homebrew, so there’s nothing additional to install.
To use Homebrew to install Visual Studio Code, execute the following command:
![For For](/uploads/1/3/4/2/134221338/528630978.jpg)
The application will install:
You’ll find the application in your
Applications
folder, just as if you’d installed it manually.To remove it, use
brew cask uninstall
:Homebrew will remove the installed software:
It performs a backup first in case the removal fails, but once the program is fully uninstalled, the backup is removed as well.
Step 6 — Uninstalling Homebrew
If you no longer need Homebrew, you can use its uninstall script.
Download the uninstall script with
curl
:As always, review the contents of the script with the
less
command to verify the script’s contents:Once you’ve verified the script, execute the script with the
--help
flag to see the various options you can use:The options display on the screen:
Use the
-d
flag to see what the script will do:The script will list everything it will delete:
When you’re ready to remove everything, execute the script without any flags:
This removes Homebrew and any programs you’ve installed with it.
Conclusion
In this tutorial you installed and used Homebrew on your Mac. You can now use Homebrew to install command line tools, programming languages, and other utilities you’ll need for software development.
Homebrew has many packages you can install. Visit the official list to search for your favorite programs.
-->In this article, you'll learn how to install .NET Core on macOS. .NET Core is made up of the runtime and the SDK. The runtime is used to run a .NET Core app and may or may not be included with the app. The SDK is used to create .NET Core apps and libraries. The .NET Core runtime is always installed with the SDK.
The latest version of .NET Core is 3.1.
Supported releases
The following table is a list of currently supported .NET Core releases and the versions of macOS they're supported on. These versions remain supported either the version of .NET Core reaches end-of-support.
- A ✔️ indicates that the version of .NET Core is still supported.
- A ❌ indicates that the version of .NET Core isn't supported.
Operating System | .NET Core 2.1 | .NET Core 3.1 | .NET 5 Preview |

Unsupported releases
The following versions of .NET Core are ❌ no longer supported. The downloads for these still remain published:
- 3.0 (Release notes)
- 2.2 (Release notes)
- 2.0 (Release notes)
Runtime information
The runtime is used to run apps created with .NET Core. When an app author publishes an app, they can include the runtime with their app. If they don't include the runtime, it's up to the user to install the runtime.
There are three different runtimes you can install on macOS:
ASP.NET Core runtime
Runs ASP.NET Core apps. Includes the .NET Core runtime.
Runs ASP.NET Core apps. Includes the .NET Core runtime.
.NET Core runtime
This runtime is the simplest runtime and doesn't include any other runtime. It's highly recommended that you install ASP.NET Core runtime for the best compatibility with .NET Core apps.
This runtime is the simplest runtime and doesn't include any other runtime. It's highly recommended that you install ASP.NET Core runtime for the best compatibility with .NET Core apps.
SDK information
The SDK is used to build and publish .NET Core apps and libraries. Installing the SDK includes both runtimes: ASP.NET Core and .NET Core.
Dependencies
.NET Core is supported on the following macOS releases:
.NET Core Version | macOS | Architectures | |
---|---|---|---|
3.1 | High Sierra (10.13+) | x64 | More information |
3.0 | High Sierra (10.13+) | x64 | More information |
2.2 | Sierra (10.12+) | x64 | More information |
2.1 | Sierra (10.12+) | x64 | More information |
Beginning with macOS Catalina (version 10.15), all software built after June 1, 2019 that is distributed with Developer ID, must be notarized. This requirement applies to the .NET Core runtime, .NET Core SDK, and software created with .NET Core.
The installers for .NET Core (both runtime and SDK) versions 3.1, 3.0, and 2.1, have been notarized since February 18, 2020. Prior released versions aren't notarized. If you run a non-notarized app, you'll see an error similar to the following image:
For more information about how enforced-notarization affects .NET Core (and your .NET Core apps), see Working with macOS Catalina Notarization.
libgdiplus
.NET Core applications that use the System.Drawing.Common assembly require libgdiplus to be installed.
An easy way to obtain libgdiplus is by using the Homebrew ('brew') package manager for macOS. After installing brew, install libgdiplus by executing the following commands at a Terminal (command) prompt:
Install with an installer
macOS has standalone installers that can be used to install the .NET Core 3.1 SDK:
Download and manually install
As an alternative to the macOS installers for .NET Core, you can download and manually install the SDK and runtime. Manual install is usually performed as part of continuous integration testing. For a developer or user, it's generally better to use an installer.
If you install .NET Core SDK, you don't need to install the corresponding runtime. First, download a binary release for either the SDK or the runtime from one of the following sites:
- ✔️ .NET 5.0 preview downloads
- ✔️ .NET Core 3.1 downloads
- ✔️ .NET Core 2.1 downloads
Next, extract the downloaded file and use the
export
command to set variables used by .NET Core and then ensure .NET Core is in PATH.To extract the runtime and make the .NET Core CLI commands available at the terminal, first download a .NET Core binary release. Then, open a terminal and run the following commands from the directory where the file was saved. The archive file name may be different depending on what you downloaded.
Use the following command to extract the runtime:
Use the following command to extract the SDK:
Tip
The preceding
export
commands only make the .NET Core CLI commands available for the terminal session in which it was run.You can edit your shell profile to permanently add the commands. There are a number of different shells available for Linux and each has a different profile. For example:
Brew Install Command Line Tools
- Bash Shell: ~/.bash_profile, ~/.bashrc
- Korn Shell: ~/.kshrc or .profile
- Z Shell: ~/.zshrc or .zprofile
Edit the appropriate source file for your shell and add
:$HOME/dotnet
to the end of the existing PATH
statement. If no PATH
statement is included, add a new line with export PATH=$PATH:$HOME/dotnet
.Also, add
export DOTNET_ROOT=$HOME/dotnet
to the end of the file.This approach lets you install different versions into separate locations and choose explicitly which one to use by which application.
Install with Visual Studio for Mac
Visual Studio for Mac installs the .NET Core SDK when the .NET Core workload is selected. To get started with .NET Core development on macOS, see Install Visual Studio 2019 for Mac. For the latest release, .NET Core 3.1, you must use the Visual Studio for Mac 8.4.
Install alongside Visual Studio Code
Visual Studio Code is a powerful and lightweight source code editor that runs on your desktop. Visual Studio Code is available for Windows, macOS, and Linux.
While Visual Studio Code doesn't come with an automated .NET Core installer like Visual Studio does, adding .NET Core support is simple.
- Download and install Visual Studio Code.
- Download and install the .NET Core SDK.
- Install the C# extension from the Visual Studio Code marketplace.
Install with bash automation
The dotnet-install scripts are used for automation and non-admin installs of the runtime. You can download the script from the dotnet-install script reference page.
The script defaults to installing the latest long term support (LTS) version, which is .NET Core 3.1. You can choose a specific release by specifying the
current
switch. Include the runtime
switch to install a runtime. Otherwise, the script installs the SDK.Note
The command above installs the ASP.NET Core runtime for maximum compatability. The ASP.NET Core runtime also includes the standard .NET Core runtime.
Docker
Brew Command For Mac Os
Containers provide a lightweight way to isolate your application from the rest of the host system. Containers on the same machine share just the kernel and use resources given to your application.
.NET Core can run in a Docker container. Official .NET Core Docker images are published to the Microsoft Container Registry (MCR) and are discoverable at the Microsoft .NET Core Docker Hub repository. Each repository contains images for different combinations of the .NET (SDK or Runtime) and OS that you can use.
Brew Command For Mac Catalina
Microsoft provides images that are tailored for specific scenarios. For example, the ASP.NET Core repository provides images that are built for running ASP.NET Core apps in production.
