Tailored for UK legal practitioners and e-discovery teams, this technical reference addresses the evidentiary challenge presented when files have been deleted or removed from a Mac but leave persistent index traces behind. Operating on ISO 17025-aligned procedures, the material examines how macOS Spotlight indexes rich file metadata, creation dates, origin provenance, and attributes, demonstrating how index remnants can reliably establish that a departed file once existed on a live device or external medium. Across its practical sections, it covers the technical mechanics of metadata dating, system logs, snapshots, and broader device estate architecture alongside necessary forensic limits and common analytical mistakes. For CPR Part 35 expert reporting, legal teams are provided with specific drafting aids, suggested instruction wording, questions to ask opponents or forensic providers, and checklists to identify red flags during disclosure. By explaining how to turn a Mac catalogue into robust legal evidence with full chain of custody documentation, the text ensures practitioners can effectively evaluate digital artefacts, avoid misinterpreting file attributes, and determine precisely when urgent preservation or specialist laboratory intervention is required.

Can metadata show where a file came from?
A file is not on the Mac. Can you still show it was there?
Isn't the "created" date just when the document was written?
How reliable is the origin ("where from") data?
Does an index entry prove someone intended to do something?
