 <!-- Note, this content is taken from linux-scripted-manual.md but changed for macOS. Any fixes should be applied there too, though content may be different -->
 
 As an alternative to the macOS installers for .NET, you can download and manually install the SDK and runtime. Manual installation is usually performed as part of continuous integration testing. For a developer or user, it's generally better to use an [installer](https://dotnet.microsoft.com/download/dotnet).
 
-First, download a **binary** release for either the SDK or the runtime from one of the following sites. If you install the .NET SDK, you won't need to install the corresponding runtime:

 - ✔️ [.NET 6 downloads](https://dotnet.microsoft.com/download/dotnet/6.0)
 - [All .NET downloads](https://dotnet.microsoft.com/download/dotnet)
 
-Next, extract the downloaded file and use the `export` command to set `DOTNET_ROOT` to the extracted folder's location and then ensure .NET is in PATH. This should make the .NET CLI commands available at the terminal. For more information about .NET environment variables, see [.NET SDK and CLI environment variables](../tools/dotnet-environment-variables.md#net-sdk-and-cli-environment-variables).

For more information about .NET environment variables, see [.NET SDK and CLI environment variables](../tools/dotnet-environment-variables.md#net-sdk-and-cli-environment-variables).
 
-Alternatively, after downloading the .NET binary, the following commands can be run from the directory where the file is saved to extract the runtime. These commands also make the .NET CLI commands available at the terminal and set the required environment variables. **Remember to change the `DOTNET_FILE` value to the name of the downloaded binary**:

 ```
 
-> [!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.
