Oct 25, 2019 How to switch between Libraries in Photos for Mac. When you create a new library, you may still want to go back to a previous library for something. Fortunately, it's easy to switch between multiple libraries. Make sure that Photos is not open (quit if it is). Hold down the Option key on your keyboard. Double-click on Photos.
Photos makes it easy to create and switch between libraries. That’s good when photos need to be kept completely separate. For instance, a real estate agent might want to keep personal photos separate from house photos taken for work. But too much separation is annoying—you have to keep switching between libraries, and it’s easy to import new photos into the wrong one.
If you struggle with multiple Photos libraries, never fear—you can merge them. Unfortunately, the process is slow, can require a lot of disk space, and may result in the loss of some metadata. You have three options: merging through iCloud Photos, using the PowerPhotos utility, and merging by exporting and importing. Each has pros and cons.
Merge through iCloud Photos
Apple’s iCloud Photos service offers the best solution for merging libraries. The trick is that whenever you designate a library as your System Photo Library, Photos automatically uploads all images that aren’t already present, adding them to the photos already in iCloud Photos. It also retains all the metadata surrounding your photos—titles, keywords, albums, facial recognition, projects, and more.
On the downside, using iCloud Photos almost certainly won’t be free unless you have so few photos that the combined library will fit within the free 5 GB of iCloud space Apple gives everyone. Almost everyone will have to pay for additional storage space ($0.99 per month for 50 GB, $2.99 for 200 GB, or $9.99 for 2 TB) for at least the month in which you’re doing the merge. iCloud Photos is a good service, so it’s likely worth paying for anyway.
More problematic is that the iCloud Photos way of merging will be very slow. If you haven’t already started using it, it could take a week or more to upload many thousands of photos. Plus, it will probably download the entire cloud-based collection of photos to each library whose photos you want to merge, so you may need a lot of local disk space too.
If you haven’t previously used iCloud Photos, go to System Preferences > iCloud and click the Options button next to Photo. In the dialog, select iCloud Photos.
Now, starting with the smallest Photos library and working up in size, follow these steps for each library you want to merge:
When you’re done, the last Photos library becomes the one you’ll keep, and you can delete the others. Needless to say, make sure you have good backups first!
Merge with PowerPhotos
The $30 PowerPhotos from Fat Cat Software provides a variety of extra capabilities when working with Photos. It helps you to create and manage multiple libraries, copy photos between libraries, find duplicates, and—most important for this topic—merge libraries.
Because PowerPhotos is working entirely on your Mac’s drive, it’s fast and it doesn’t require huge amounts of extra disk space. Unfortunately, unlike the iCloud Photos approach, which brings in both originals and any edits to those photos, PowerPhotos can import only your original photos or the versions that you’ve edited, not both. Plus, it can’t merge facial recognition data, smart albums, or print projects.
PowerPhotos provides an actual interface for merging too—choose Library > Merge Libraries to start.
In the window that appears, you have four tasks:
Merge by Exporting and Importing
This final option is conceptually simple. You export all the photos from one library and then import them into another. It’s even what Apple recommends. The main thing it has going for it is that it’s free, and it will be faster than the iCloud Photos approach. It could also be useful if you want to copy a subset of photos between libraries, rather than merging all photos.
However, as with PowerPhotos, you have to choose between original and edited photos, and you’ll need a lot of extra disk space. Even worse, you’ll lose even more metadata, including albums, faces, and print projects. And if you export as JPEG, your photos may also suffer a slight quality drop as they’re recompressed.
For those who want to use this approach, Apple provides detailed instructions. In essence, you’ll click Photos in the sidebar to see everything, and then choose Edit > Select All. Then you’ll choose File > Export and either Export X Photos (to get the edited versions of images) or Export Unmodified Original for X Photos (to get the original images). Once everything has exported, you’ll switch libraries in Photos and then drag the folder of exported images back into Photos to import it.
Our nod goes to the iCloud Photos technique, but PowerPhotos is a fine utility for those who aren’t perturbed by its limitations. Of course, don’t start any merging without making backups first, and if you need help, don’t hesitate to call us.

Smart Albums are like regular albums, but smarter, obviously. They're great for helping you quickly organize images without the need of manually adding each one to an album because it's all automated.
Smart Albums have a large number of different parameters, such as photos, faces, aperture, ISO, Live Photo, RAW, Portrait, and more. With all of these options, you can create many different Smart Albums to suit whatever it is you need.

One of the coolest things about Photos is that it intelligently groups all of your photos and videos into moments, collections, and years.

The Moments, Collections, and Year views are only available in macOS Mojave and older.
In the Year and Collections views, thumbnails can be small. You can click-and-hold and then drag the cursor in any direction over the thumbnails to get a larger preview. Letting go will take you directly to the image that the cursor was last on.

How to create a new library with Photos for Mac
You can create a new library for your photos at any time with Photos for Mac. To do so, make sure that you quit Photos and reopen it with the following method to get the Library options.
You've now created a brand new Photos Library. Unfortunately, there is no easy way to migrate over photos and video, so you will need to export the content you want, and then import it back into the new library.

How to move your Photos library to an external hard driveManage Multiple Iphoto Libraries
If you're low on storage space on your Mac, you can just move your Photos Library to an external hard drive. Keep in mind though, that you will need to have this external drive plugged in to access your Photos Library, even if you have iCloud Photo Library enabled. And you aren't able to create a second Photos Library that has iCloud Photo Library enabled on your Mac, so be wary.
This process may take a while, depending on how big your Photos library is.
A note on reference libraries
The Photos app technically supports the management of images that aren't locally stored within its library — that is, you can keep a set of images in a folder called 'October Trip' and manage them within Photos without having to make a separate copy of them. You can do this by navigating to Photos > Preferences from the menu bar, selecting the General tab, and unchecking the 'Copy items to the Photos library' box under Importing.
That said, reference libraries won't play nicely with iCloud Photo Library users; you may run into problems when syncing, or not be able to sync at all. So if you plan on using a reference library, you'll have to opt out of iCloud Photo Library. Merging multiple photo libraries mac.
I also didn't have any luck getting referenced files to sync properly with Photos — I'd delete a photo, but the reference file would stay in its original location, even after deleting it from the 'Recently Deleted' folder. Not sure if that's a bug or just not how Photos wants us managing referenced photos, but worth noting.
