+# Using MSAL Python with an Authentication Broker on macOS
+
+>[!NOTE]
+>macOS authentication broker support is introduced with `msal` version 1.31.0.
+
+Using an authentication brokers on macOS enables you to simplify how your users authenticate with Microsoft Entra ID from your application,
+as well as take advantage of future functionality that protects Microsoft Entra ID refresh tokens from exfiltration and misuse.
+
+Authentication brokers are **not** pre-installed on macOS but are applications developed by Microsoft, such as [Company Portal](/mem/intune/apps/apps-company-portal-macos). These applications are usually installed when a macOS computer is enrolled in a company's device fleet via an endpoint management solution like [Microsoft Intune](/mem/intune/fundamentals/what-is-intune). To learn more about Apple device set up with the Microsoft Identity Platform, refer to [Microsoft Enterprise SSO plug-in for Apple devices](/entra/identity-platform/apple-sso-plugin).
+
+## Usage
+
+To use the broker, you will need to install the broker-related packages in addition to the core MSAL from PyPI:
+
+```bash
+pip install msal[broker]>=1.31,<2
+```
+
+>[!IMPORTANT]
+>If broker-related packages are not installed and you will try to use the authentication broker, you will get an error: `ImportError: You need to install dependency by: pip install "msal[broker]>=1.31,<2"`.
+
+Typically, on macOS your [public client](/entra/identity-platform/msal-client-applications) Python applications would [acquire tokens](../getting-started/acquiring-tokens.md) via the system browser. To use authentication brokers installed on a macOS system instead, you will need to pass an additional argument in the `PublicClientApplication` constructor - `enable_broker_on_mac`:
+
+```python
+from msal import PublicClientApplication
+
+app = PublicClientApplication(
+    "CLIENT_ID",
+    authority="https://login.microsoftonline.com/common",
+    enable_broker_on_mac =True)
+```
+
+>[!IMPORTANT]
+>If you are writing a cross-platform application, you will also need to use `enable_broker_on_windows`, as outlined in the [Using MSAL Python with Web Account Manager](wam.md) article.
+
+In addition to the constructor change, your application needs to support broker-specific redirect URIs. For _unsigned_ applications, the URI is:
+
+```text
+msauth.com.msauth.unsignedapp://auth 
+```
+
+For signed applications, the redirect URI should be:
+
+```text
+msauth.BUNDLE_ID://auth
+```
+
+If the redirect URIs are not correctly set in the app configuration within the Entra portal, you will receive error like this: 
+
+```text
+Error detected... 
+tag=508170375
+context=AADSTS50011 Description: (pii), Domain: MSAIMSIDOAuthErrorDomain.Error was thrown in location: Broker 
+errorCode=-51411 
+status=Response_Status.Status_Unexpected 
+```
+
+Once configured, you can call `acquire_token_interactive` to acquire a token.
+
+```python
+result = app.acquire_token_interactive(["User.ReadBasic.All"],
+                    parent_window_handle=app.CONSOLE_WINDOW_HANDLE)
+```
+
+>[!NOTE]
+>The `parent_window_handle` parameter is required even though on macOS it is not used. For GUI applications, the login prompt location will be determined ad-hoc and currently cannot be bound to a specific window. In a future update, this parameter will be used to determine the _actual_ parent window.
+
+## Token caching
+
+The authentication broker handles refresh and access token caching. You do not need to set up custom caching.
