 ## Set up Visual Studio
 
-To enable development and debugging in Visual Studio, add your Azure AD user in Visual Studio by selecting **File** > **Account Settings** from the menu, and click **Add an account**.
+### Windows
+Visual Studio for Windows is integrated with Azure AD authentication. To enable development and debugging in Visual Studio, add your Azure AD user in Visual Studio by selecting **File** > **Account Settings** from the menu, and click **Add an account**.
 
 To set the Azure AD user for Azure service authentication, select **Tools** > **Options** from the menu, then select **Azure Service Authentication** > **Account Selection**. Select the Azure AD user you added and click **OK**.
 
 You're now ready to develop and debug your app with the SQL Database as the back end, using Azure AD authentication.
 
+### MacOS
+
+Visual Studio for Mac is not integrated with Azure AD authentication. However, the [Microsoft.Azure.Services.AppAuthentication](https://www.nuget.org/packages/Microsoft.Azure.Services.AppAuthentication) library that you will use later can use tokens from Azure CLI. To enable development and debugging in Visual Studio, first you need to [install Azure CLI](https://docs.microsoft.com/cli/azure/install-azure-cli) on your local machine.
+
+Once Azure CLI is installed on your local machine, sign in to Azure CLI with the following command using your Azure AD user:
+
+```bash
+az login --allow-no-subscriptions
+```
+You're now ready to develop and debug your app with the SQL Database as the back end, using Azure AD authentication.
