To recover an earlier project file, open its folder in Finder, enter Time Machine, choose a backup from before the unwanted changes, and restore the file. If the project’s app supports document version browsing, you may be able to restore or copy an older version from inside the app instead. The right method depends on whether you need to replace the current file or preserve both versions.

Before restoring, protect the current project

If the current project contains anything you might still need, make a separate copy before restoring. In Finder, select the project file and use File > Duplicate; keep the duplicate outside the folder where Time Machine will restore the older file. Give it a clear name so you can identify it later. If the project is a folder containing linked assets, duplicate the whole project folder rather than only its main document.

A project file may depend on other files, such as images, audio, or linked media. If you need the project as it existed at a particular point, consider whether those related files also need to come from the same backup date. Time Machine can restore multiple selected items, including folders, but restoring a folder affects its contents too. Apple says restored items return to their original locations, so inspect your selection before clicking Restore. Apple’s Time Machine restore guide

Restore the project from a Time Machine backup

  1. Connect or make available the disk that contains your Time Machine backup. In Finder, open the folder where the project file is normally stored. Starting in the right folder makes it easier to navigate to the corresponding file in a backup.

  2. Open Time Machine. Apple documents opening it through Spotlight, or—in current macOS instructions—by clicking the Time Machine menu bar icon and choosing Browse Time Machine backups. If that icon is missing, open Apple menu > System Settings > Control Center, find Time Machine, and choose Show in Menu Bar. Apple’s instructions for browsing Time Machine with Spotlight

  3. Use the timeline or the arrows beside the Finder window to move to a backup from before the change. Check the dates as you browse. A gray timeline mark may still be loading or validating; wait for it before choosing a version. Select the project file you want, then click Restore. Apple says the restored item returns to its original location.

  4. When the restore finishes, open the project and check that it contains the expected work. If you made a safety copy, keep it until you have confirmed that the restored project and any required assets open correctly.

Try the app’s version browser when available

For some documents, an app offers File > Revert To > Browse All Versions. Apple documents this for many apps, but availability and behavior depend on the app and document. Browse the timeline, inspect the older version, then choose Restore to make it current or hold Option and choose Restore a Copy to create a separate document. Choose Done to leave the current document unchanged. Apple’s guide to viewing and restoring document versions

This route is useful when you want to compare an earlier document version without restoring it through Finder. It is not a universal feature for every project format: if Browse All Versions is absent or does not show the version you need, use Finder and Time Machine instead. App version history and Time Machine backups are distinct ways to find prior work; either one can only show versions it has retained.

If the version you need does not appear

First confirm that you are in the project’s original folder and that you have selected the intended backup date. If the file was moved, renamed, or deleted, search may help: Apple describes starting a Finder search and opening Time Machine from the menu bar to browse matching backed-up items. Apple’s Time Machine and Spotlight recovery guide

If the expected backup is unavailable, the project may not have been included in the backups you can access, or the backup history may not extend far enough. Time Machine cannot restore a version that is absent from the available backup history. Check other backups or the project app’s own version browser if applicable; avoid overwriting the current project until you have found and checked the older copy.
