If your Mac is running low on storage or cluttered with duplicate files, a duplicate file finder can help you quickly locate and remove redundant files. These tools scan your system, compare file contents, and allow you to safely delete duplicates. Here are two of the best free duplicate file finders for Mac. You can use them on an old Intel or new Apple Silicon Mac.

Its smart algorithm ensures fast and accurate results, making it a great choice for advanced users. You can download it from dupeGuru's official site.

I used Windows 11 before, and I used tools like best duplicate file finder for mac to find duplicate photos on mac. But after I switched to Mac, I found that there was no "Find Duplicate Files" option in Finder...😭 But later I found that Finder + Smart Folders can actually filter duplicate files manually. Although it is not as convenient as automatic scanning, it is still good to use.

1. Open Finder and click "File" → "New Smart Folder" in the top menu.
2. Click "+" in the upper right corner, and then select the search criteria, such as:
3. File type (pictures, videos, documents, etc.)
4. Creation date/modification date (find recently downloaded or copied files)
5. File size (duplicate files are usually the same size)
6. Change the sorting method to "Name" or "Size", so that the same files will be arranged together for manual deletion.

I used this method to find a bunch of duplicate photos and videos in the Downloads folder. Although it is a bit more manual than software like best duplicate file finder for macbook, it does not require the installation of additional tools, and there is no need to worry about accidentally deleting important files. Suitable for those who don't want to install software but want to clean up their Mac hard drive! 🔥🔥🔥

If you're looking for a free duplicate file finder for Mac, I recommend trying out DupeGuru. It's a user-friendly app that scans for duplicates across different file types and can help you reclaim precious storage space. Another good option is Gemini 2, which has a free trial version—though you may need to pay for the full version if you want all the features. Just remember, when removing duplicates, you’re risking some emotional turmoil.

A duplicate file finder is a tool that helps identify and remove duplicate files on your computer. These tools scan directories and compare files based on different criteria such as name, size, or checksum to detect duplicates. Removing duplicates helps free up disk space and organize files efficiently.

You can use built-in command-line tools like find, md5, sha256sum, or fdupes to locate duplicate files in macOS. Now, generate checksums (unique file signatures) and look for duplicates.

Open Terminal. Navigate to the directory you want to scan. Run the following command to list duplicate files based on MD5 checksums:

find . -type f -exec md5 {} + | sort | uniq -w 32 -d

This calculates the MD5 hash of all files in the directory. It then sorts the results and removes unique entries, leaving only duplicates. To get a list of duplicate file paths:

find . -type f -exec md5 {} + | sort | uniq -w 32 -d | awk '{print $2}'

In addition, you can used a third-party duplicate file finder for macOS called fdupes, a dedicated command-line tool for finding and deleting duplicate files.

brew install fdupes
fdupes -r /path/to/your/folder
fdupes -r /path/to/your/folder
fdupes -rd /path/to/your/folder

These two methods efficiently help find duplicate files on macOS via the terminal. Let me know if you need more help on this.

I usually use Windows 11, but I have to switch to Mac occasionally for work. Some time ago, I also encountered the problem of my hard drive being full of duplicate photos. Manual cleaning was too troublesome... After a round of research, I finally found several useful duplicate file finder for mac methods, sharing with you!

Method 1: Use Finder + Smart Folder 
Mac's built-in Finder can actually help you find duplicate files on mac. Although it is not smart enough, you don't need to install software.

1. Open Finder and click File → New Smart Folder.
2. Click the "+" sign in the upper right corner, and then filter by file type, date, and size.
3. Manually compare the file name and size to find duplicate files.
4.  Suitable for small-scale sorting, but if there are many files, this method is too time-consuming...

Method 2: Use Terminal Command
If you know a little about command lines, you can use Terminal commands to find duplicate files.
Open Terminal (Applications → Utilities).

Enter the following command to let Mac find duplicate files (for example, in the Downloads folder):

find ~/Downloads -type f -exec md5 {} \; | sort | uniq -w32 -d

This command will list the duplicate file paths according to the file MD5 checksum calculation.
You can delete these duplicate files manually.

 Advantages: Pure Mac built-in function, no software installation required.
Disadvantages: Need to know some terminal operations, and only list the file path, will not automatically delete.

Method 3: Use Duplicate File Finder on Mac 
If you are too lazy to toss and want to get it done quickly, then use a tool like Duplicate File Finder for Mac, scan + delete in one step.
Recommend a few useful ones:

• Duplicate File Finder (free version works, paid version unlocks more features)
• dupeGuru (open source and free, the interface is a bit ugly but useful)
• Easy Duplicate Finder (trial version can scan, but you have to pay to delete)

If you have a lot of files, it is recommended to use a tool like duplicate file finder for Mac directly, which saves time and effort!
