Start with these three steps
Pause normal work
Avoid downloads, software installation and cleanup on the affected storage. Use another device for research and cloud checks when practical.
Check the relevant recovery location
Inspect Finder Trash for ordinary files, Recently Deleted in Photos, or the cloud provider’s recovery area. Recover only the items you recognise.
Record the deletion history
Note the time, folder, application and whether Trash or Recently Deleted was emptied. Include any copying, reinstall or scan performed afterwards.
Recover from the application that removed the item
Files in Finder Trash can often be returned before Trash is emptied. Photos has its own Recently Deleted area, and eligible iCloud Drive files can be recovered through iCloud.com within its retention period. Clearing one recovery area is different from merely moving an item into it.
Start with a known filename or event rather than restoring a large ambiguous set. Check the recovered item’s contents and destination. On a shared iMac, confirm which user account performed the deletion so that you are looking in the relevant place.

Search an earlier copy with the right date
A Time Machine search can locate a file in an earlier backup. If the file was overwritten rather than removed, a supported app’s saved versions may also help. Use the period before the unwanted change, not merely the newest date shown.
Check emailed attachments, exported folders and separately saved project copies. Keep multiple candidates until you have compared them. A final PDF may recover the information you need immediately even if the original editable document requires further investigation.

The physical storage changes what remains possible
On SSDs, TRIM and internal cleanup can remove access to deleted content independently of visible new file writes. For that reason, stopping work is worthwhile but cannot guarantee that an undelete scan will find the original bytes.
Identify whether the affected location was the iMac’s internal storage, an external disk or a Fusion setup. Keep the original configuration intact. Do not turn a missing-file case into a freshly formatted disk just because software recommends initialising or rebuilding it.
Make any scan a considered choice
If no retained copy exists, weigh the importance of the files against further activity on the source. For irreplaceable material, an assessment can establish whether imaging or another controlled route is appropriate before a long software scan.
If a recovery tool is used on suitable, stable storage, install it elsewhere and save results to a separate destination. Do not accept a list of filenames as proof of success. Check representative files for complete content, correct dates where available and necessary linked assets.
A realistic view of recovery
- Recently Deleted cannot return an item that has been permanently removed from that service.
- Overwriting, SSD processing, lost metadata or encryption constraints can prevent recovery or reduce it to incomplete files.
