What is macOS System Data, and why is it consuming your storage in 2026?
In 2026, many users running macOS Tahoe 26.2 find that “System Data” consumes hundreds of gigabytes. This is often caused by hidden Microsoft 365 Outlook profiles, legacy Apple Mail logs, or redundant iCloud cache files that are invisible to the Finder. Rather than risking your data with “cleaning” apps, Keith Thomas provides expert on-site maintenance to safely identify and purge these files at your home or office in London and the South East.
