+    The 'services.podman' module now supports Darwin (macOS) with declarative
+    machine management.
+
+    On Darwin, podman requires running containers inside a virtual machine.
+    The new configuration options allow you to declaratively manage podman
+    machines with automatic creation, configuration, and startup.
+
+    By default, a machine named 'podman-machine-default' will be created
+    automatically. You can customize machines or disable the default with:
+
+      services.podman.darwin.useDefaultMachine = false;
+      services.podman.darwin.machines = {
+        "my-machine" = {
+          cpus = 4;
+          memory = 8192;
+          diskSize = 100;
+          autoStart = true;
+        };
+      };
+
+    The module includes a launchd-based watchdog service that automatically
+    starts configured machines on login and keeps them running.
