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:
My favorite method to merge two different Photos libraries is as follows: Pick the 'main' library you want to drop the content into. You'll lose information such as your albums and other data besides the photos from the other library. I'll refer to the other library as 'second library' from here on. PowerPhotos provides an actual interface for merging too—choose Library Merge Libraries to start. In the window that appears, you have four tasks: Choose source libraries. You aren’t limited to merging just two libraries; you can pick multiple sources. Choose the destination library. This is the library you want to receive all the 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When macOS Yosemite was released in 2014, the Photos app finally came to Macs, replacing outdated iPhoto.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:
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.
Import photos from external drives to the Photos app on your Mac
Import photos from your camera
If you have several libraries in the Photos app, merge them into one
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:
Go to Launchpad
Hold down the Option key, and then double-click on the Photos app to see the libraries you have on this device
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:
Hold down the Option key
Double-click on the Photos apps
Click the Create New button, then choose Library
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:
Launch Photos holding down the Option key and select one the libraries you want to merge
In the menu bar, click Edit > Select All
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.
Pick where they’re going (this could be a folder on your Mac or a connected external drive, for example)
Repeat these steps for the other libraries you want merged
Now close Photos and re-open using Option to select the library you are merging these photos into
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
Download Gemini 2 for Mac and launch it
Click Scan for Duplicates
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.
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.<
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:
Launch Photos
Click the + button next to My Albums in the sidebar
Select Smart Album<
Give your Smart Album a name
Choose the Parameters, e.g. “kids,” “days out,” “Holiday 2018.” You can modify these at any time.
Click OK to create
By developing a system (e.g., photos are grouped into albums by date taken) and using Smart Albums, you’ll make sure your photo library is easy to navigate, even if it contains thousands of photos from 2001 and up until now.
That’s it, hope this short guide helps you cope with your photo overload. And remember: the best way to organize photos on your Mac is to keep your library lean and manageable — free from clutter and useless copies. Gemini 2 will gladly help with that.

Your Photos library holds all your photos, albums, slideshows, and print projects. If your library is large, and you want to free up storage space on your Mac, turn on iCloud Photo Library and use Optimize Mac Storage, or move your library to an external drive.
Before you start, be sure to back up your library.
Prepare your drive
You can store your library on an external storage device, such as a USB or Thunderbolt drive formatted as APFS or Mac OS Extended (Journaled).1 Find out how to check the format of your external storage device.
To prevent data loss, Apple doesn't recommend storing photo libraries on external storage devices like SD cards and USB flash drives, or drives that are shared on a network.
Move your Photos library to an external storage device
Quit Photos.
In the Finder, go to the external drive where you want to store your library.
In another Finder window, find your library. The default location is Users > [username] > Pictures, and it's named Photos Library.
Drag your library to its new location on the external drive. If you see an error, select your external drive's icon in the Finder, then choose File > Get Info. If the information under Sharing & Permissions isn't visible, click , then make sure the 'Ignore ownership on this volume' checkbox is selected. If it's not selected, click to unlock it, enter an administrator name and password, then select the checkbox.2
After the move is finished, double-click Photos Library in its new location to open it.
If you use iCloud Photo Library, designate this library as the System Photo Library.
Delete original library to save space
After you open your library from its new location and make sure that it works as expected, you can delete the library from its original location.
In a Finder window, go back to your Pictures folder (or whichever folder you copied your library from) and move Photos Library to the trash. Then choose Finder > Empty Trash to delete the library and reclaim disk space.
Open another Photos library
If you have multiple libraries, here's how to open a different one:
Quit Photos.
Press and hold the Option key while you open Photos.
Select the library that you want to open, then click Choose Library.
Photos uses this library until you open a different one.
