How do I restore one file or an older version from Time Machine?
Short answer: Open the folder in Finder, enter Time Machine, go back on the timeline, select the file and click Restore. Recent versions may come from local snapshots.
Open a Finder window on the folder where the file was (or is), then enter Time Machine from its menu bar icon or the Time Machine app. Use the timeline on the right to go back to a date, select the file and click Restore.
If a file with the same name exists, macOS asks whether to keep both or replace it. Recent versions may come from local snapshots even if the backup drive isn't connected.
