Here’s how to delete duplicate photos on Mac with this duplicate photo finder for Mac:
Step 1: Install and execute Tenorshare Cleamio on your Mac. Then, click “+” to add one or more folders to scan for duplicate photos. Hit “Scan.”
Step 2: You can also customize scan settings in “Preferences.” Preview the detected duplicate photos after the scan.
Step 3: Select photos manually or use “Select Old / Select New” to choose in bulk. Next, pick a location. Hit “Remove” to remove duplicate photos on Mac.
Option B: Use the Photos App
You can also delete duplicates in Mac Photos app automatically with an in-built “Merge” feature that merges duplicate pictures. Next, the app keeps the highest-quality version with all edits and metadata and deletes duplicates in Mac Photos that are moved to the “Recently Deleted” album. They are permanently erased after 30 days. This method removes exact duplicate files that are completely identical.
However, it may not catch similar photos, such as multiple shots of the same scene, or slightly different images. Also, it can be slow to scan large libraries for duplicates and requires you to manually select which files to merge. This method also doesn’t allow sorting photos by size, making it harder to identify and delete small files like thumbnails. Here’s how to remove duplicates in Photos app on Mac:
Step 1: Open the Photos app on your Mac. Then, find “Duplicates” beneath “Utilities” in the sidebar.
Step 2: The app automatically detects duplicate photos and videos. Select individual items, multiple rows, or press “Command-A” to select all.
Step 3: Tap “Merge.” Confirm to keep the highest-quality version while combining metadata like captions, keywords, and favorites.
Step 4: The app will delete duplicates in Mac Photos by sending the merged ones to “Recently Deleted.”
Option C: Use Finder
Finder doesn’t have a built-in duplicate photo finder for Mac, but you can use Smart Folders to locate and remove duplicate photos on Mac without extra software or cost. It gives you full control to review files before removing them and lets you set specific search criteria.
However, the process is manual and time-consuming, and can only detect duplicates based on basic info like name or size. It also carries a higher risk of accidentally erasing the wrong files. Here’s how to find duplicate photos on Mac with Finder:
Step 1: Open Finder. Then, head to “File.” Choose “New Smart Folder.” Click “+.” Next, select “Kind.” Tap “Image” to filter images.
Step 2: Add more criteria like “Name,” “File Size,” “Date Created,” or “Date Modified” to narrow results.
Step 3: Employ “Quick Look” (space bar) to preview images. Check file locations to avoid removing unique files. Select duplicates.
Step 4: Afterward, press “Command + Delete.” Then, empty the “Trash” to remove the duplicate pictures permanently. That’s how to find duplicate photos on Mac with Finder.

| Method | Time Required | Accuracy | Ease of Use | Best For | Risk of Mistakes |
| Manual Deletion | More (slow speed) | High if careful | Moderate | Small libraries | High |
