The bad news is that duplicate files are eating up space on your Mac potentially causing your Mac to slow down and perform poorly. The good news is that there is an easy way to get rid of duplicate files with just a couple of clicks. The easy way is to use the best duplicate file finder for Mac.

There are a number of apps to find and delete the duplicate photos, videos, music files, documents and other types of duplicate files on a Mac. They vary in performance, ease of use and more. In this article, you will find a list of them along with a review for each.

What makes a reliable duplicate file finder for Mac?

Capability of identifying duplicate files

A duplicate file finder is an app designed to detect duplicate files. Such apps use particular algorithms to compare files and identify the duplicates. Different apps may use different algorithms. For example, the algorithm PhotoSweeper uses can only handle images, resulting in its inability to find other types of duplicates. Easy Duplicate Finder uses SHA-256, which is a bit slow. Cisdem Duplicate Finder uses a combination of algorithms, leading to high performance in the detection of various types of duplicate files.

Safe support for Photos and iTunes (now Music)

Unlike on Windows where photos and music files are stored in normal folders, the photos and songs on your Mac are typically stored in Photos Library (managed via Photos app) and iTunes Media (managed via iTunes app) respectively. The fact is that many duplicate file finders for Mac will consider Photos Library and iTunes Media normal folders when searching for duplicates in the two places. As a result, they will damage your library or cause the loss of files or related data. To safely delete these duplicates, you need to use an app designed for Photos and iTunes.

There are other criteria to consider. The two ones above are the most important.

The best duplicate file finders for Mac

#1 Cisdem Duplicate Finder

Compatibility: macOS 10.10 or later, including Big Sur

Cisdem Duplicate Finder is the best of its kind due to its high performance, safety, ease of use, etc.

Thanks to the advanced algorithms it uses, the app can quickly identify true duplicate files by content and find duplicate photos, audios, videos, Word documents, PDFs, presentations, archives and other types of duplicate files on your Mac and external storage devices (e.g., external hard drives, SD cards and more). It also finds near-duplicate photos, which is a plus for making the app a great duplicate photo finder for Mac.

Designed for Photos and iTunes, Cisdem Duplicate Finder will scan your Photos Library or iTunes Media, display the found duplicates for you to view, and remove the unwanted duplicates from within the Photos app or iTunes app with your permission, just like a human would when removing photos or songs. Your Photos Library and iTunes Media will be safe and unaffected except being duplicate-free.

Once the app finishes scanning Photos, iTunes or Mac folders for duplicate files, it will display the detected duplicates in its results window for you to easily view and preview. What’s more, its smart Auto-Select feature will automatically select duplicates for you to mass delete with a single click. Click the Delete button, and now all dupes are gone! If not satisfied with auto-selection, you can manually select or use the selection rules provided.

Compatibility: macOS 10.10 or later

In addition to the best duplicate file finder for Mac, there are other great apps available to help rid your Mac of duplicate files. Gemini 2 is one of them. People are often impressed by how good looking the app is. But a beautiful interface can only be the cherry on top. What’s important is the ability to find duplicate files on a Mac.

The app supports finding the double files in normal folders, iTunes and Photos and is capable of detecting duplicate photos, duplicate audios, duplicate documents and some other types of duplicates. It does a good job of deleting duplicate files in folders even the large ones. But it occasionally fails to work when scanning a big Photos Library. In such a case, try to re-scan.

Best Free Duplicate File Remover

In February 2021, Gemini 2 introduced the Duplicates Monitor feature aiming to better help users get rid of duplicate files by notifying users when new duplicates appear. The feature does what it’s designed for. But it uses lots of CPU and may slow down your Mac.

Pros

1. Comes with a beautiful interface
2. Scan your Mac for various types of duplicate files
3. Support Photos and iTunes
4. Let users directly preview files within the app
5. Provide an innovative Duplicates Monitor feature

2. Expensive

#3 Tidy Up 5

Compatibility: macOS 10.12 or later

Designed by Hyperbolic for “pro users” (as advertised), Tidy Up 5 is a good duplicate file finder for Mac for experienced users. Inexperienced users may find its interface overwhelming and confusing.

Supporting all popular file types such as images, Tidy Up 5 can detect and delete the duplicate files in Mac’s folders and Photos. Although the app offers an option to scan iTunes for duplicate items, it does a poor job. In the test, it failed to find any duplicates, which do exist, in my iTunes.

The app comes with two modes: Simple mode and Advanced mode. New users can start with the simple one. Both modes offer an array of scan options and criteria. Each scan for duplicates requires (at least) a little configuration. Compared to the other best Mac duplicate file finders talked about above, this one is less easy to use.

Pros

2. Find and delete duplicates in Apple Photos on Mac

Its wizard-style interface is simple to navigate and use, guiding users through the whole process of the identification and removal of duplicate files, which is especially helpful for novice users.

This piece of file deduplication software can scan your MacBook Pro, MacBook Air or iMac, etc. for duplicate songs, duplicate photos and more. When the scan is complete, it will give you two options: using Auto Remove to immediately eliminate duplicates or using Manual Review to view duplicates and then remove the unwanted ones. The latter allows you to examine the files you are handling and deleting and is more reliable.

The app excels at looking for the duplicates in iTunes and normal folders. However, when searching for duplicate photos in Mac Photos app, it will return no results or false positives. If you allow it to deduplicate, your Photos Library will get damaged.

Pros

1. Capable of detecting common types of file duplicates
2. Support iTunes
3. Provide an Auto Remove feature for quick duplicate removal
4. Very user-friendly interface

Cons

1. Relatively slow scan
2. Poor support for Mac’s Photos
3. A bit expensive

#5 Duplicate Detective

Compatibility: macOS 10.7 or later

This Mac duplicate file finder and remover looks less sophisticated due to its unpolished interface. It actually does a fair job of scanning for and removing duplicate files on Mac.

You can use it to scan folders and Photos. However, it can’t identify all the duplicates in a given folder or library. Some dupes will be missing. And also, it can’t provide consistent performance. If you want to clean up duplicates in iTunes, this app won’t help. In the test, the duplicate songs it found didn’t even exist in my iTunes.

Pros

1. Support all common file types
2. Can find the duplicates in Photos on Mac
3. Offer an option to create an alias when deleting duplicates
4. Easy to use

Pros

1. Able to look for photo duplicates and other common types of duplicates
2. Lightweight
3. Ease-to-use interface

Cons

1. Can’t identify the duplicates in iTunes and Photos

#7 dupeGuru for Mac (free)

Compatibility: macOS 10.12 or later

There are also free Mac apps available for the removal of duplicate files. What is the best free duplicate file finder for Mac? dupeGuru may be the answer.

dupeGuru is free to use and open source. There is some sort of maintenance, but the app hasn’t been properly updated for years. Therefore, there can be compatibility issues with newer macOS versions.

The freeware app comes with three modes: Standard, Music and Picture, allowing you to look for and delete duplicate pictures, duplicate music files and some others in folders on Mac. It’s not designed for Apple Photos and iTunes. Even though it allows you to scan Photos Library, its deduplication algorithm will damage your library and cause data loss.

4. Fairly configurable
5. Can find certain visually similar pictures
