To keep your Mac running smoothly and reliably, you need to prevent your hard drive from becoming full. You could, of course, just get a larger hard drive when your current one starts reaching its limits, but that would not only be expensive but also time-consuming, requiring you to manually transfer macOS and your personal files.
Instead, it’s a much better idea to get rid of duplicate files using one of the Macintosh duplicate file finders listed in this article. A capable Mac duplicate finder can quickly and reliably locate all files that are present on your hard drive more than once, allowing you to delete them with a single click.
Gemini is the most popular software for removing duplicate files on Mac. It’s developed by the people behind CleanMyMac X and The Unarchiver, so you can expect a beautiful user interface with a lot of attention to detail.
This duplicate finder for Mac lets you scan individual folders as well as your entire hard drive, and scans are always fast and accurate regardless of the size of the job. When Gemini is done searching duplicate files on your Mac, it lets you select which duplicates you want to delete and which you want to keep.
Its smart algorithm remembers the choices you make and automatically applies them during future scans to save you time. The latest version of Gemini addresses the problem of partial duplicates, which are a major concern of photographers, who often take multiple variations of the same picture to ensure that the subject is in focus.
When the Mac duplicate file finder detects multiple pictures that are similar but not identical, it lets you compare them and delete everything but the best version. If you make a mistake and accidentally shred the wrong picture, you can bring it back from Trash in a click.
Duplicate Sweeper is a cross-platform duplicate file remover Mac and Windows users can use to locate and delete duplicate photos, videos, music, documents, and other files. The software offers two modes of operation: automatic and manual. As their names imply, the former makes it possible to automatically delete duplicates based on their file attributes, while the latter lets you manually select each duplicate you want to get rid of.
In addition to locating duplicates in usual locations, such as the Document folder, Duplicate Sweeper can look for them in places like Google Drive, iCloud Drive, and OneDrive. Found duplicates can be previewed using the built-in file viewer before you send them to Recycle Bin (PC) or Trash (Mac).
Duplicate Sweeper is a one-time purchase of $20, and a single license gives you the right to install the software on one Mac. If you decide that you don’t like how Duplicate Sweeper works or performs within 30 days of your purchase, you can request a full refund by contacting its support staff.
The latest version of Disk Drill, one of the most powerful data recovery software applications, includes a free duplicate finder whose performance and functionality rival many dedicated duplicate file finders for Mac.
To find duplicate files on Mac with Disk Drill’s duplicate file finder, you simply need to download the program from its official website, install it on your Mac, and click Find Duplicates. You will then be able to add any folder you want and scan it with a single click. Once Disk Drill is done searching duplicate files in the specified location or locations, it will let you choose which files you want to remove.
Just like all other extra disk tools included with Disk Drill, the duplicate file finder has a modern user interface that’s both intuitive and nice to look at. Should you ever make a mistake and accidentally delete the wrong duplicate file, you can easily recover it using Disk Drill’s advanced data recovery algorithms, which can recognize over 400 file formats across all commonly used file systems.
Unlike the built-in duplicate file finder, the data recovery portion of Disk Drill is not free, and you need to purchase a license for $89.00 to recover deleted files.
dupeGuru is an open source duplicate file finder Mac, Windows, and Linux users can download, install, and use completely free of charge. Thanks to its quick fuzzy matching algorithm, dupeGuru is highly efficient and capable of discovering hundreds of duplicates in a very short amount of time.
The freeware application can technically find all kinds of duplicates, but it works best with audio files and photos. Its special Picture mode can detect all pictures that are very similar but not exactly identical. A feature like this can be a godsend in the day and age of digital cameras and camera-equipped smartphones, which make it all too easy to snap multiple photos in quick succession.
Because the source code of dupeGuru is publicly available, you can rest assured, knowing it won’t harm your Mac or install malware. This excellent free duplicate file finder for Mac, Windows, and Linux has been translated into English, French, German, Chinese (Simplified), Czech, Italian, Armenian, Russian, Ukrainian, Brazilian, and Vietnamese.
Easy Duplicate Finder claims to have been downloaded by millions of users from all over the world. While that might be an exaggeration, there’s no denying that this paid application is one of the best duplicate file finders Mac users can use to reclaim valuable storage space. Thanks to its step-by-step wizard-style interface, Easy Duplicate Finder is perfect for beginners who have no previous experience with deleting duplicate files.
The entire process is broken down into three simple steps. First, you select the folders you want to scan. Then, you begin the actual scan and wait for it to finish. Finally, you choose which duplicates you want to remove. If you don’t have enough time to choose each duplicate manually, you can take advantage of the bulk-selection option and let Easy Duplicate Finder do everything for you.
Because Easy Duplicate Finder is a paid software application, you need to purchase a license to remove duplicate files on your Mac. The least expensive license costs $39.95, and it includes unlimited updates for 1 year. That’s also the main reason why we can’t rank this application higher on this list of the best duplicate file finders for Mac.
Speedy Duplicate Finder is a no-frills software that finds duplicate files on Mac, Windows, and Linux machines. The first thing you notice when you launch it is its clean and simple user interface, which is divided into two main sections: a pane with available disks and folders on the left and an overview of found duplicates on the right.
To start the deduplication process, all you need to do is click the Scan button and sit back. As one of the fastest tools to find duplicate files on Mac OS X and macOS, Speedy Duplicate Finder can scan around 10,000 in less than half a second, depending on the performance of your hard drive.
You can then apply smart filters to sort all found duplicates by Kind, Extension, or Size. The free version of Speedy Duplicate Finder is not really free because it doesn’t support unlimited deleting. For that, you have to purchase a license for $25. Alternatively, you can get Speedy Duplicate Finder as part of a discounted bundle that includes all apps developed by Qiplex.
Just because we decided to place Tidy Up at the end of this list doesn’t mean that it’s not one of the best Mac duplicate file finders available—it certainly is! It’s just that it starts from $29.99 and works only on macOS 10.12.0 or newer. Aside from these two downsides, Tidy Up has a lot to offer to users who are interested in finding duplicate files on Mac.
For starters, it has two distinct modes for finding and removing duplicate files. The first mode is called Simple, and it’s intended for less experienced users who don’t need all the features supported by this duplicate finder. The second mode is called—you’ve guessed it—Advanced, and it lets you refine search criteria to find only specific duplicates, such as photos taken at the same location or files with the same size.
Regardless of which of the two modes you choose, Tidy Up always takes just a short amount of time to deliver scan results and present them in a tabbed results window, with one tab for each major category of files, such as music, movies, archives, and documents.
With a capable duplicate file finder, finding and removing duplicate files on Mac is a simple process that can be broken down into just three steps:
If you want to delete, let’s say, duplicate photos from your last vacation, there’s no need to scan your entire hard drive. The good news is that most duplicate file finders let you find duplicate files on your Mac’s hard drive as well as in specific folders.
Some duplicate file finders let you customize a whole host of scan options, while others are more straightforward and offer virtually no customizability at all. Keep in mind that finding duplicate files on Mac is guaranteed to slow down your computer a bit, so pick an appropriate time to begin the scan process.
It’s likely that there will be many duplicate files scattered all over your Mac’s hard drive. Instead of blindly deleting them in one go, we highly recommend you take the time to review each and every file individually so that you don’t accidentally delete something valuable.
