If you shoot as much as the next photographer, most of your hard drive is taken over by pictures. Now, try to imagine how many of them are duplicate photographs or just visually really-really similar? Chances are, the answer is a lot.

With a digital camera, you shoot about 10-15 takes from one angle or of one posture before you’re satisfied, right? And then you only choose one for editing. That’s 14 pictures that you will never need right there, and that’s every scene of every photoshoot.

You must already be thinking about getting an external hard drive or buying cloud storage and moving your gallery, because your Mac’s space is not infinite. Or you might have already done that. Anyway, in the long run, billions of photos you no longer need keep piling up and it seems like there’s no escape from it. But worry not, there is.

Solution: The best photo duplicate finder for Mac

The problem with duplicate and visually similar photos is so commonplace that here at MacPaw we created a professional duplicate image finder, Gemini 2. Let’s take a closer look at how it can help you sort your photos.

How to delete duplicate photos on Mac with Gemini 2

The most convenient way to remove duplicate photos would be to hash the photo files and look for duplicate hashes. The flipside that a couple of the most widely used hashing algorithms for tasks like this, MD5 and SHA-1, have documented “collisions,” where two inputs will produce the same output, which should theoretically never happen in a hashing algorithm.

First, you need to find duplicate photographs in your gallery. Then you have to figure out which version to delete in each case. All that takes loads of time if done manually, and Gemini 2 does 90% of the work for you.

To find duplicate photos on your Mac, do the following:

  1. Download Gemini for free and launch it
  2. Click Scan for Duplicates. Your Home folder is pre-selected, so Gemini 2 will check all files on your Mac.
  3. When the scan is over, hit Review Results
  4. All the duplicate photos you have on your Mac will be grouped under All Duplicates > Images. Click on the group of photos to view them (Gemini has a built-in photo preview).

    5. Bonus tip: If you switch to grid view using the icon at the top, you’ll see bigger previews of duplicate photos. Double click on a group of duplicates to see all copies side-by-side, along with their metadata and location. The icons at the top will highlight the differences between the duplicates, such as location or date modified.

  5. Once you choose which copies you want to delete, check mark them and proceed to the next set of duplicate images by using those little arrows on the sides.
  6. Finally, click Smart Cleanup to delete all selected photos. And don’t worry, Gemini moves pics to a separate Gemini Duplicates album in Photos, so you can look through them once again before you give the final “Delete” command. That’s because Apple won’t let any third-party app delete anything from the Photos library.

If you think you have too many files in your Home folder and want to focus on pictures, try scanning just the Photos app. Here’s how to find duplicates in Apple’s Photos app:

  1. Download Gemini for free and launch it
  2. Click Restart Now, and then the big “+” in the middle of the screen
  3. Select the Pictures folder and hit Scan for Duplicates
  4. Follow steps 4-6 from the tutorial above

The Pictures folder contains your Photos library, so this should help you remove all the duplicate photos you have in there.

How to get rid of not-quite-duplicate photos

Once you have duplicates off your Mac, it’s time to take a look at similar photos. See, Gemini distinguishes between exact duplicate photos, which are several instances of the same image, and similars — photos that have different editing or were shot at slightly different angles.

For instance, here are two pictures with and without editing, in the same folder. Gemini will find them for you and mark as similar.

Or here are three pictures that were taken a second apart. You definitely don’t need all three, unless you’re going for an art-housy installation on majestic horse breathing.

How to remove duplicates from Photos manually

Frankly, I couldn’t find a straightforward way to find duplicate photos in Mac’s Photos app. While the app does give you a heads up if you’re trying to import a pic that already exists, once the duplicate or similar images are there, you’re on your own. However, here are a few helpful tips on removing duplicates in Photos for Mac:

  • View your pics sorted by date (they are automatically sorted that way in the Photos tab). The Photos app groups pictures by the date taken, not the date they were imported. It’s safe to assume your duplicate photos were taken on the same day, so you’ll spot them more easily when they are side-by-side.
  • Try Smart Albums as a way of narrowing down your search. If for some reason Photos doesn’t detect the date taken, you can group your photos by the file name, camera model, and other parameters that might suggest they were taken at the same time. For duplicate photos that have different file names and image formats, criteria like the person in the photo might work.

Final word on removing duplicate photos

We all know that euphoric state in which you return home with an SD-card full of new pictures. We’ve all been there, editing feverishly to publish or print them right away. It’s ok to be a little messy in that moment, but months later you notice that your whole Mac is a mess.

Don’t let those useless files eat up the drive space you need for future photoshoots. There’s nothing more frustrating than the “Startup Disk is almost full” alert when you’re uploading new pictures. It’s best to deal with space wasters with Gemini 2 long before that happens.

Have a good day and may the Photoshop be with you.

With cameras so readily available, it’s easy to accumulate more photos than you know what to do with. You probably take dozens of pictures when you go out, meet up with friends, or go on vacation. And while taking photos is fun, organizing them is work. But it doesn't have to be that way. In this article, we’ll show you how to organize photos on your Mac in three easy steps:

  1. Merge your photo libraries in the Photos app
  2. Delete unwanted photos
  3. Group pictures using Smart Albums in Photos

Step 1. Consolidate all your photos in the Photos app for Mac

When macOS Yosemite was released in 2014, the Photos app finally came to Macs, replacing outdated iPhoto. Now with Photos, you’ve got more organization tools, including the ability to switch between libraries and merge them.

To start with, let’s get all of your photos from different places onto your Mac. Here’s what you should do:

  1. Use iCloud Photo Library to ensure that everything you take on an iOS device is synced automatically with your Mac. Alternatively, AirDrop photos from your iPhone and/or iPad to your Mac.
  2. Import photos from external drives to the Photos app on your Mac
  3. Import photos from your camera
  4. If you have several libraries in the Photos app, merge them into one

How To Merge Photos Libraries Without Duplicates

Once everything is on your Mac and in one library, it’s easier to get organized. Let’s take a look at a few questions most people have when they juggle several Photos libraries.

How do I switch libraries in Photos?

Libraries in Photos can come from a few different sources, including external devices such as cameras and iPhones. If you were using iPhoto prior to Photos, each device and source will have a Systems Photo Library. You can switch between them, and here is how you do that:

  1. Go to Launchpad
  2. Hold down the Option key, and then double-click on the Photos app to see the libraries you have on this device
  3. Now you can move easily from one photo library to another and open the one you want by double-clicking it

How to create a new Photo library on Mac?

Creating a new library is easy. If Photos is open, you’ll need to quit and reopen to create a new library:

  1. Hold down the Option key
  2. Double-click on the Photos apps
  3. Click the Create New button, then choose Library
  4. Give your new library a name and click OK

How to merge two or more Photos libraries?

At present, there is no native macOS tool for merging libraries in Photos. Essentially, what you’ll be doing is moving all pics to one new library. So, create one as described above, and then follow these steps:

  1. Launch Photos holding down the Option key and select one the libraries you want to merge
  2. In the menu bar, click Edit > Select All
  3. Again in the menu bar, select File > Export. Now you’ve got the following options:
    • Export Unmodified Original. This will export every image in these libraries, excluding any edits or changes made to them.
    • Export [number of photos you want to export] Photos, which gives you the option to pick a format and select Full Size. That will export your photos as they are, with any edits you’ve made, in TIFF, PNG, or JPEG formats.
  4. Pick where they’re going (this could be a folder on your Mac or a connected external drive, for example)
  5. Repeat these steps for the other libraries you want merged
  6. Now close Photos and re-open using Option to select the library you are merging these photos into
  7. Either use File > Import or drag the exported photos into the library

How do I delete a Photo library from my Mac?

If you want to delete a library, it’s super easy. You just navigate to the Pictures folder on your Mac, locate the library you want gone, and move it to the Trash. However, you’ll want to make sure you’ve got all the images and videos out of it first. Export them like we described in the previous section, and then trash the library.

Step 2. Remove duplicates and other useless photos

Now that you've merged libraries — which can take a while if you’ve got a lot of photos scattered across different locations — you’ve probably got a whole load of duplicates and similar images. Chances are, you had the same photo on an external HDD and on your Mac and now it’s duplicated, or you had a dozen slightly different variations of the same shot. Sure, you might want to keep one or two, but do you really need the other 11 wasting space on your Mac? Probably not. Here is how you delete redundant photos from a Mac without it taking all evening.

How to delete duplicates in Photos

  1. Download Gemini 2 for Mac and launch it
  2. Click Scan for Duplicates
  3. It will scan every photo, album and folder on your Mac, including those on any connected external hard drives and imported from the iCloud Photo Library. Once complete, click Review Results.
  4. Gemini has a photo preview mode, so you can see every image, including metadata. Your duplicates are grouped under Exact Duplicates > Images, and similar photos will be under Similar > Images. Use the icon at the top to see a grid view, making it easier to identify which copy you want to delete.<
  5. Tick the box next to each image you want to delete, then click Remove

Gemini places these in a separate folder in Photos (Gemini Duplicates), giving you a possibility to look through the images once again before deleting them for good. For more information, this article is well worth a read.

Step 3. Use Smart Albums in Photos to organize your pics

After merging your libraries and clearing out duplicates and similar images, take photo organizing one step further and group the remaining pics with Smart Albums. Let’s take a look at how to use this fantastic feature of the Photos app to your advantage.

What are Smart Albums in Mac’s Photos app?

Smart Albums are a way of grouping images by the parameters you set. Maybe you’ll want an album to contain photos taken last Christmas, or you’d rather group all the pics of your kid together. All that and more can be done with a Smart Album. As is the case with a regular Photos album, you can edit and delete it.

How to make a new Smart Album in Photos

Creating a new Smart Album is simple:
