Core Overcharged Mac OS
STEP 2: INSTALL MAC OS X In order to boot the Mac OS X Retail DVD, you'll need to download and burn iBoot. For desktops and laptops using unsupported Intel CPUs and graphics, a legacy version of iBoot can be downloaded here. If you have an Ivy Bridge or Haswell system, you can’t use the default iBoot. Use iBoot Ivy Bridge or iBoot Haswell. For example, the ASP.NET Core repository provides images that are built for running ASP.NET Core apps in production.

In this article, you'll learn how to install .NET on macOS. .NET is made up of the runtime and the SDK. The runtime is used to run a .NET app and may or may not be included with the app. The SDK is used to create .NET apps and libraries. The .NET runtime is always installed with the SDK.
The latest version of .NET is 5.0.
Supported releases
The following table is a list of currently supported .NET releases and the versions of macOS they're supported on. These versions remain supported either the version of .NET 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 5.0 |
|---|---|---|---|
| macOS 11.0 'Big Sur' | ✔️ 2.1 (Release notes) | ✔️ 3.1 (Release notes) | ✔️ 5.0 (Release notes) |

| macOS 10.12 'Sierra' | ✔️ 2.1 (Release notes) | ❌ 3.1 (Release notes) | ❌ 5.0 (Release notes) |
Unsupported releases
The following versions of .NET 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. 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 two different runtimes you can install on macOS:
ASP.NET Core runtime
Runs ASP.NET Core apps. Includes the .NET runtime..NET 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 apps.
SDK information
The SDK is used to build and publish .NET apps and libraries. Installing the SDK includes both runtimes: ASP.NET Core and .NET.
Dependencies
.NET is supported on the following macOS releases:
| .NET Core Version | macOS | Architectures | More information |
|---|---|---|---|
| 5.0 | High Sierra (10.13+) | x64 | More information |
| 3.1 | High Sierra (10.13+) | x64 | More information |
| 3.0 | High Sierra (10.13+) | 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 runtime, .NET SDK, and software created with .NET.
The runtime and SDK installers for .NET 5.0 and .NET Core 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 (and your .NET apps), see Working with macOS Catalina Notarization.
libgdiplus
.NET 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 5.0 SDK:
Download and manually install
As an alternative to the macOS installers for .NET, 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 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 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 and then ensure .NET is in PATH.
To extract the runtime and make the .NET CLI commands available at the terminal, first download a .NET 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 commands to extract the runtime or SDK that you downloaded. Remember to change the DOTNET_FILE value to your file name:
Tip
The preceding export commands only make the .NET 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:
- 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 SDK when the .NET workload is selected. To get started with .NET development on macOS, see Install Visual Studio 2019 for Mac.
| .NET SDK version | Visual Studio version |
|---|---|
| 5.0 | Visual Studio 2019 for Mac version 8.8 or higher. |
| 3.1 | Visual Studio 2019 for Mac version 8.4 or higher. |
| 2.1 | Visual Studio 2019 for Mac version 8.0 or higher. |
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 installer like Visual Studio does, adding .NET support is simple.
Mac Os Mojave
- Download and install Visual Studio Code.
- Download and install the .NET 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 previous command installs the ASP.NET Core runtime for maximum compatability. The ASP.NET Core runtime also includes the standard .NET runtime.
Docker
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 can run in a Docker container. Official .NET 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.
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.
For more information about using .NET Core in a Docker container, see Introduction to .NET and Docker and Samples.

Apple introduced the concept of CoreStorage volumes in OS X 10.7 (Lion), and currently most hardware shipped by Apple will ship configured with a Core Storage volume enabled.
Deep Freeze Mac currently does not support CoreStorage nor Fusion Drive. If you are attempting to install Deep Freeze and get the following error: 'This version of Deep Freeze cannot be installed on a Mac with FileVault turned on.', or Error 0xE00002c2 when attempting to use the product your system is configured with a Core Storage device.
To verify that the system in question is configured with a Core Storage Volume and that a Fusion Drive is present, open Terminal and type 'diskutil cs list' (without the quotes). The output will tell you if CoreStorage present or not. A sample of the output is below;
Machines configured with a Fusion drive will show two logical volumes as opposed to one listed like the bold text in the example above. In the event that a single volume is shown you may be able to revert the Core Storage volume back to a traditional volume using the information linked below;
In the event that two volumes are listed you will need to break the Core Storage volume and reinstall the operating system on a single volume using the instructions below.

Please note: The steps listed below will cause data loss. Do not attempt these unless you have a working backup of any information stored on the computer in question.
Mac Os Versions
Resolution (to remove CoreStorage volume and reinstall OS):
- Start the Mac and hold down Option key to select the startup disk, and Choose the Recovery HD. Alternatively you can hold down Command and R keys to start from the Recovery partition. For more info, refer to Apple’s support document: OS X Recovery.
- From the Utilities menu, select Terminal
- On the prompt, type 'diskutil cs list' and copy the UUID of the Logical Volume Group (see the highlighted section in the image)
- Type 'diskutil cs delete <UUID>' to remove the CoreStorage volume. Note: the OS will be deleted after this step and you will need to reinstall it later
- Once the operation has completed, quit Terminal and from the OS X Utilities window, select Disk Utility to reformat the hard drive.
- After formatting, run Terminal again and execute the command newfs_hfs to construct the HFS file system. The goal here is to create HFS volume with allocation block size set to 4096 bytes, so use the following parameters: 'newfs_hfs -b 4096 -J [-v volume_name]', where -J tells to create a journaled HFS+ volume, and -v is optional if you want to specify a volume name (default is Untitled).
- quit Terminal and from the OS X Utilities window, select Reinstall OS
- Follow the instruction provided by Apple to reinstall the OS: OS X Mountain Lion: Reinstall OS
If you have more than one Mac to process, you will need to perform steps 1 - 4 on each of the Mac. You can then create a disk image of the freshly installed OS (using Steps 1 to 6), and use your favourite deployment method/software to install the OS on all your Macs.
