To check whether an earlier copy of a Mac file may be available, use Time Machine to browse for that file and use Disk Utility to see whether APFS snapshots exist on its volume. These checks answer different questions: Disk Utility lists snapshots for a volume, while Time Machine lets you look for and restore a particular file version. A snapshot listing alone does not prove that a specific file is recoverable.

What counts as a snapshot or a backup?

An APFS snapshot is a read-only copy of an APFS volume from a point in time. Time Machine can create local snapshots on the same disk as the original files, separate from backups saved to a backup disk. Apple says local snapshots are created on APFS disks when automatic Time Machine backups are enabled; they are generally retained for up to 24 hours or until space is needed. Apple’s guide to local snapshots

A Time Machine backup on an external or network disk is a separate copy stored away from the Mac’s internal disk. That separation matters if the Mac or its internal storage fails. A local snapshot can help recover an earlier version while the Mac is working, but it is not a substitute for a separate backup. Apple’s Time Machine backup guide

Check for APFS snapshots in Disk Utility

  1. Open Disk Utility from Applications or by searching with Spotlight.
  2. Choose View > Show APFS Snapshots.
  3. Select the relevant APFS volume in the sidebar.
  4. Review the snapshot table at the bottom of the window. The Date Created and Kind columns can help identify entries; choose the More menu and Show Columns if those columns are hidden.

Apple documents this view as a way to list snapshots associated with the selected volume and inspect metadata such as creation date, UUID, and kind. If the volume has no entries, Disk Utility is showing no snapshots for that selected volume at that time. Check that you selected the volume containing the file, rather than a different volume in the sidebar. Apple’s Disk Utility instructions

This is a volume-level inventory, not a file-by-file report. Disk Utility does not show which individual files are inside a snapshot or confirm that a particular file can be restored from it. Snapshot names or dates also do not, by themselves, establish whether a needed file version is present. Avoid using the Delete Snapshot control when your goal is recovery; deleting an entry can remove a recovery point.

Check whether the file is recoverable with Time Machine

Open the folder where the file belongs in Finder. Open Time Machine from its menu-bar icon and choose Browse Time Machine Backups; if the icon is not shown, enable it in Control Centre settings or use Spotlight to open Time Machine. Navigate through the dates and inspect the folder for the file or earlier version you need. When you find it, select the item and choose Restore. Apple says restored items return to their original location. Apple’s restore instructions

A backup disk may need to be connected or available on the network for its backups to appear. If it is encrypted, you may need its password. When a backup disk is unavailable, Time Machine can use eligible local snapshots; reconnecting the backup disk can make additional backups available. Apple also notes that the latest local snapshot date is not reflected in the latest backup date shown in Time Machine settings. Apple’s local snapshot guide

Interpret the result carefully

If you can browse to the file at an earlier date in Time Machine, you have evidence that Time Machine can present a recoverable copy from that available history. If Disk Utility lists snapshots but Time Machine cannot find the file, the listing alone does not establish that the file is in one of those snapshots or that it can be restored. If neither view reveals a usable version, check that you selected the correct folder and volume, and connect any backup disk you use. The absence of a visible snapshot is not proof that no separate backup exists; check the backup disk through Time Machine as a distinct step.

For ongoing protection, confirm that Time Machine is configured with a separate backup destination and that a recent backup completes. Apple’s Time Machine settings and menu show backup status and the date of the latest backup; they do not report the latest local snapshot date. Apple’s backup setup and status guide
