Assemble an image workflow

Use image workflows to customize your image.

Use image workflows to create OS X NetBoot and NetInstall images. Workflows let you manually define the contents of your image in System Image Utility.

An image workflow must start with the Define Image Source action and end with the Create Image action. Also, actions in a workflow must be connected. If not, the workflow is invalid and the actions aren’t processed.

  1. Log in as an administrator user.

  2. Open System Image Utility (in the /System/Library/CoreServices/ folder).

  3. In the image source list, click the triangle to the left of Sources.

  4. From the expanded list, select the image source.

    When you select the source, this action chooses a default image type based on the contents of the selected source.

  5. Choose which type of image you’re creating (NetInstall, NetBoot, or NetRestore).

  6. Click Customize for advanced image creation options.

    This opens the workflow pane and Automator Library.

    The Define Image Source action is present as the first component in the workflow.

  7. Configure the Define Image Source action for your image.

    This action is required at the beginning of all image workflows.

  8. From Automator Library, choose additional actions that your customized image requires and drag them into the Workflow pane between the Define Image Source action and the Create Image action.

  9. Assemble the actions in the order you like, configuring each action as you go.

    For information about configuring the actions, see About workflows.

  10. Add the Create Image action to the end of your workflow.

    This action is required at the end of the image workflow.

  11. Save the workflow by clicking Save, enter the name of your workflow in the Save As field, then choose where to save the workflow.

    To save the workflow somewhere else, choose a location from the Where pop-up menu or click the triangle next to the Save As field and navigate to a folder.

  12. Click Save.

  13. To start the workflow, click Run and authenticate if prompted.

    Important:  Don’t attempt to edit content in the image destination folder while the image is being created.
