Start with these three steps
Describe one missing item
Record a filename fragment, the app that created it, its approximate date and the user account you normally used. A concrete example makes a large search manageable.
Check existing locations
On a stable iMac, inspect Finder, Trash, the relevant cloud account and any normally connected archive disk. Avoid cleanup tools while searching.
Preserve current work
Keep a separate copy of any newer document before restoring an older version. If the iMac freezes or its storage clicks, stop and use a storage assessment instead.
Start with the user account and actual folder
Check the app’s recent-document list and note the folder path when an item opens. On a shared household iMac, confirm that you are using the account that created the file. A new or migrated account can show an empty Desktop even though the original user’s material has not been deleted.
Desktop and Documents can be stored in iCloud Drive. Apple explains that turning this feature off leaves the existing files in iCloud and creates new local folders. Check both locations before moving anything; several similarly named folders are a reason to compare contents carefully.

Recover from the location that held the file
For an ordinary local deletion, inspect Trash and use Put Back when available. For an iCloud Drive deletion, check iCloud.com’s recovery options. Apple provides a 30-day window for eligible files, but permanently removed items cannot be restored through that feature.
Search from another working device if the iMac itself is unstable. An email attachment, exported PDF or collaborator’s copy may satisfy the immediate need, even while the original editable document remains missing.

Retrieve the version you actually need
If the document opens but the contents are wrong, check whether its app offers File > Revert To > Browse All Versions. Apple also describes restoring a copy, which helps preserve the current document while comparing earlier work.
A Time Machine backup may contain a useful version from before the change. Match the backup date to when the document was correct. Open the restored result and check several pages, worksheets or linked assets before assuming the problem is resolved.

If macOS will not load
A healthy disk may be accessible without completing normal startup. Intel iMacs can use target disk mode where supported; Apple silicon iMacs use Share Disk from macOS Recovery. Both require suitable hardware, a working enough Mac and any necessary unlock credentials.
Treat these as copying routes for stable storage. If copying stalls repeatedly or the device disappears, stop. Record the important folder paths for assessment rather than repeatedly trying to transfer the entire user account.

A realistic view of recovery
- A filename appearing in search does not prove the complete file can be opened.
- A cloud-only item may need retrieval from its cloud service rather than recovery from the iMac’s internal storage.
