Recovering files from an SD card on Mac follows the same principle as on Windows — stop writing to the card, then scan before new data overwrites deleted files. macOS-specific considerations include APFS compatibility, Homebrew-based tools, and Full Disk Access permissions.
Part 1. Stop Using the Card Immediately
Remove the SD card from your camera or reader before taking any further action:
- Do not take new photos
- Do not copy files to the card
- Do not format the card
⚠️ Important: Every write to the card — including camera auto-saves and thumbnail generation — overwrites sectors containing deleted files. Remove the card from the camera before reviewing shots on-screen.
Part 2. Connect via a USB Card Reader
Built-in SD card readers on older Macs (pre-2016) may not support UHS-II speed class cards. If the card is not detected:
| Connection Method | Reliability | Notes |
|---|---|---|
| Built-in Mac SD slot | Moderate | Pre-2016 Macs may miss UHS-II cards |
| USB-C card reader | High | Recommended for modern Macs |
| USB-A card reader | High | Works on older Macs |
| USB hub | Lower | Avoid — reduces stable power |
💡 Tip: Open Disk Utility → View → Show All Devices after connecting the card. If it appears greyed out, click Mount. If it shows as RAW, run First Aid before attempting recovery.
Part 3. Free Recovery: PhotoRec via Homebrew
PhotoRec is free, open-source, and recovers unlimited files. Install via Homebrew:
brew install testdisk
photorec
Select the SD card from the device list, choose file types (JPG, CR2, NEF, etc.), and set a destination folder on your Mac's internal drive — not the SD card itself.
💡 Tip: In PhotoRec, select only the file types you need. Scanning for all types on a 128 GB camera card produces tens of thousands of files — filtering by extension (e.g., CR2 for Canon RAW, NEF for Nikon) keeps results manageable.
Part 4. Mac-Specific Recovery Considerations
| Recovery Factor | Mac Behavior | Action |
|---|---|---|
| Full Disk Access | Required for recovery tools | System Settings → Privacy & Security → Full Disk Access |
| Apple Silicon (M-series) | Supported | Grant Full Disk Access before scanning |
| APFS formatted SD | Uncommon but possible | Tools with APFS support required |
| exFAT (64 GB+) | Most common | Standard recovery applies |
🗣️ r/mac user: "PhotoRec via Homebrew recovered all my Sony ARW files from a formatted card. Took 20 minutes on a 64 GB card. The key was connecting the card reader before launching the app."
Part 5. Recover SD Card Files on Mac With Ritridata
Ritridata recovers deleted and formatted photos from SD cards on Mac — with vendor-specific algorithms for Canon (CR2/CR3), Nikon (NEF), Sony (ARW), and DJI camera cards on both Intel and Apple Silicon.
🗣️ r/photography user: "My SD card corrupted mid-shoot on my Canon R5. Used a Mac-native recovery tool with Canon-specific algorithms — got back all 400+ CR3 RAW files intact."
Step 1 — Insert the SD card via reader and select it from the drive list
Step 2 — Run a scan — reads exFAT/FAT32 sectors for photo file signatures
Step 3 — Preview RAW photos and recover to your Mac's internal drive
FAQ
What is the best free tool to recover SD card files on Mac? PhotoRec via Homebrew (brew install testdisk then photorec) is the best free option. It supports unlimited recovery of CR2, NEF, ARW, JPG, and video formats from formatted or corrupted SD cards.
Can I use Disk Utility First Aid to recover deleted photos? First Aid repairs file system errors but does not recover deleted files. Run it first if the card shows errors — if files are still missing after First Aid, use data recovery software.
Does recovery work on exFAT SD cards on Mac? Yes — exFAT is the default format for SD cards over 32 GB. Mac reads exFAT natively and recovery software scans exFAT sectors directly.
