Mac Tools API

The Mac Tools API topic covers the choices behind desktop automation: which layer to use, how to prepare the target, and how to interpret the result. A maintainable workflow makes those choices visible to the next person who needs to run or debug it.

Choose the layer that fits the task

Start by checking whether the target application provides a documented way to perform the task. A direct interface may be appropriate for moving or exporting data, while interface automation may be appropriate when the visible interaction is what you need to verify.

Control the starting state

Record the permissions and user-session assumptions needed by the chosen mechanism. Avoid making a workflow depend on an unexplained collection of prior approvals or a specific window arrangement. Confirm the target application and document before an action that changes state.

Validate the boundary

A browser workflow running on a Mac is still a browser workflow. Keep its page context and browser identity distinct from a native application test. If the task crosses both boundaries, name each handoff and explain how the next step receives its context.

• Describe the application or document you expect to control.
• Check prerequisites before starting the meaningful action.
• Bound execution with a timeout and cancellation plan.
• Separate setup errors from action and verification errors.
• Release resources created by the workflow.

Make the result useful to someone else

Save the outcome in a consistent format with a run identity, target context, and a short explanation of failure when one occurs. Include a screenshot only when it helps explain the result. A clear event record and a stable output file are often enough to make the next step understandable.
