If you are using the M1 Mac

1. Confirm your cpu architecture

   ls /usr/local/share/dotnet/

2. This may be x64 or x86. Set a variable to store the cpu arch

   arch="x64"

3. Confirm your dotnet version

   dotnet --version

4. Set a variable to store the version

   version="5.0.403"

5. Run the following commands

   sudo rm -rf /usr/local/share/dotnet/$arch/sdk/$version

   sudo rm -rf /usr/local/share/dotnet/$arch/shared/Microsoft.NETCore.App/$version

   sudo rm -rf /usr/local/share/dotnet/$arch/shared/Microsoft.AspNetCore.All/$version

   sudo rm -rf /usr/local/share/dotnet/$arch/shared/Microsoft.AspNetCore.App/$version

   sudo rm -rf /usr/local/share/dotnet/$arch/host/fxr/$version

6. Some of the above folders may not exist but that is fine. Confirm that no dotnet sdk is still present

   ls /usr/local/share/dotnet/$arch/sdk/ dotnet --version

To uninstall dotnet core from MacOS, using dotnet-uninstall-tool.

1. Download the tool Here

2. Open terminal and change working directory to where the file (dotnet-core-uninstall.tar.gz) is located.

3. Install the Tool using following commands.

      1. mkdir -p ~/dotnet-core-uninstall
      2. tar -zxf dotnet-core-uninstall.tar.gz -C ~/dotnet-core-uninstall
      3. cd ~/dotnet-core-uninstall
   

show help: ./dotnet-core-uninstall -h

4. ./dotnet-core-uninstall list

Using this command you can check the list of .NET Core SDKS or Runtime that can be removed with this tool.

5. ./dotnet-core-uninstall remove --sdk/--runtime version --force

Eg: For remove SDK 5.0.100

./dotnet-core-uninstall remove --sdk 5.0.100 --force

If you face any Privilege issue add sudo in front of the command

6. Give the user Key (Password).

7. (Do you want to continue) hit the "Y" then enter.

Check & conform the SDK list

You might as well use dotnet-core-uninstall tool which allow you to select a specific SDK or runtime version to remove. github docs

If you are experiencing issues with building Xamarin.Mac after installing preview version of .Net 5 SDK you might like to remove Mono using such script and Visual Studio like this and try to reinstall from scratch

good luck
