Quick answer: Stop using the drive, image it if you can, run a read-only scan with a trusted tool (e.g., Disk Drill), preview results, and restore recovered files to another drive.
When you delete a file on macOS (move it to Trash or remove it permanently), the file system typically marks the file’s storage blocks as free without immediately erasing the underlying data. On APFS and HFS+, metadata that points to the file is removed or flagged, but the actual bytes often remain on disk until overwritten. That window is your recovery opportunity.
Overwrites happen when the system writes new data to those blocks. Everyday activity—saving documents, system updates, even Spotlight indexing—can shorten the recovery window. That’s why the first rule of recovery is to minimize writes to the affected disk as soon as you notice the loss.
Time Machine and snapshots can sometimes provide a straightforward restore. Check Time Machine first for a quick recovery; otherwise proceed with a dedicated recovery workflow. In enterprise or encrypted-volume cases, additional steps (like decrypting before scanning) are necessary to maximize results.
Plan your recovery before you click: act quickly, preserve the drive state, and avoid solutions that write to the affected volume. The ideal workflow reduces the chance of permanent data loss and improves scan accuracy.
Step 1: Stop using the Mac or at least the affected volume. If the file was on the startup disk, avoid creating or downloading anything new. If possible, boot another Mac or use Target Disk Mode to access the drive without mounting it as a writable volume.
Step 2: Create a forensic disk image (.dmg or .img) of the affected volume. Imaging preserves the current state and allows you to run multiple scans safely against the image. Imaging tools like macOS Disk Utility or specialized imaging utilities can do this; if you’re unfamiliar, cloning to an external drive is the next best option.
Step 3: Use a trusted recovery tool to scan the image or the drive in read-only mode. Preview recoverable files, then recover to an external destination. Always restore to a separate drive to prevent overwrites.
Disk Drill is a widely used macOS recovery application that supports APFS, HFS+, FAT32, exFAT, NTFS, and more. It offers quick scan, deep scan, filesystem rebuild, and the ability to preview files before recovery—features that matter when you want to confirm integrity before restoration.
Typical Disk Drill workflow: install Disk Drill to a different volume than the one you’re recovering, select the target disk or disk image, run a quick scan first (fast, catches recently deleted entries), then follow with a deep scan (thorough, slower) if needed. The preview pane helps verify photos, documents, and some databases before you recover.
Disk Drill’s Recovery Vault and guaranteed recovery features can prevent future headaches by keeping metadata that simplifies file restoration. For immediate recovery, focus on read-only scanning and restoring files to an external drive. You can learn a tested method in this guide: Recover deleted files on Mac with Disk Drill.

Software tools rely on readable physical media. If the drive has suffered mechanical failure (clicking, failure to mount, unusual noises) or severe electronic fault, a software scan can make things worse. In these cases you’ll need a professional lab with clean-room facilities and plate-level repair skills.
Encrypted volumes without a valid passphrase are effectively unrecoverable unless you have the key. Also, once data is overwritten, software recovery is rarely possible. If the lost data is mission-critical (legal, financial, proprietary), consult a professional data recovery service before attempting deep recovery yourself.
Cost/benefit considerations: professional recovery can be expensive but often delivers the highest success rates for physically damaged drives, RAID arrays, or SSDs with TRIM activity. Evaluate the value of your data versus the cost, and document every step for potential legal/insurance needs.
“How can I recover a deleted photo on my Mac?” — Check Trash first, then Time Machine. If not found, run a read-only scan with Disk Drill or another trusted tool and preview images before saving.
“Can I restore files after emptying Trash on Mac?” — Yes, if the disk blocks haven’t been overwritten. Stop using the drive, create an image, and run a recovery scan as soon as possible.
“Is there a built-in Mac tool to undelete files?” — Not a full undelete tool. Time Machine and APFS snapshots can restore older versions, but for permanently deleted files you’ll need third-party recovery software or professional services.

Possibly — if the disk blocks haven’t been overwritten. Turn off write activity immediately and run a read-only scan using Disk Drill or similar. Creating a disk image before scanning improves safety and success chances.
Yes. Disk Drill operates in read-only mode for scans and is considered safe when you install it on a separate drive (not the one being recovered). Always avoid restoring files back to the source disk to prevent overwriting.
If the drive is making unusual noises, failing to mount, or shows hardware errors, stop DIY attempts and consult a professional data recovery lab. Powering or spinning a failing drive can worsen the damage and reduce recovery chances.
