Overview of importing photos and videos into Photos on Mac. Import your photos and videos into your photo library so you can organize and edit them with Photos. You can import photos and videos in a variety of ways: Using iCloud: Turn on iCloud Photos on your Mac and other devices (such as iPhone, iPad, and Apple TV) to access your entire library automatically. See Use iCloud Photos to store photos.
Apple's photo management software for the Mac, Photos, has grown to be a fairly competent all-purpose storage locker. But as your photo and video library grows — and especially if you've taken advantage of iCloud Photo Library — you may find that your Photos library strains to fit on your Mac's hard drive.
While there are options to keep your Mac from running out of space, like optimizing your photo storage if you use iCloud Photo Library, it comes at a cost: Without a fully-stored Photos library, you won't be able to create secondary backups of your images and video. (And as good as iCloud has become, your photos and video are precious enough that they're worth keeping backed up in multiple places.)
There is an alternative: Moving your Photos library to an external drive (or creating an entirely separate library and syncing it with iCloud). Here's how to do it, and some reasons why you should — and shouldn't! — consider it for your needs.
Why you should (and shouldn't) use an external drive with Photos for Mac
There are a number of reasons why an external drive might make sense when you're working with Photos for Mac:
- You have a giant Photos library (and, if you use iCloud Photo Library, you want to ensure you have a secondary backup of everything in that library)
- You frequently swap computers and want to work on your images from any Mac
- Your library isn't huge, but you'd prefer to save space on your Mac for other files
- You share a computer with other users and you have limited drive space
- If you're working with space constraints on your primary computer, it's one of the easiest ways to back up your full iCloud Photo Library

That said, there are some downsides, too. Here are some reasons you might not want to use an external drive:
- You don't have a big enough library to warrant moving it off your Mac
- You don't want to have to worry about always having your external drive connected to view and edit your images
- You use a laptop frequently and can't afford an SSD, and you don't want to risk breaking your disc-based hard drive by constantly moving it
- You don't want to accidentally create duplicate libraries that can't be connected to iCloud Photo Library (because your offsite library is connected)
- Unless you purchase a speedy drive, working externally is almost always slower than working on your default hard drive
- You don't want to spend the money on an external drive
- If you use an automated backup service for your computer, you'll have to set up a second set of rules for backing up your hard drive
Best external drives for storing photos
Okay, so you've decided to move your Photos library over to an external drive. What next? If you already have an external drive, you can always use it for storing your Photos library (and save on cash). But if you're considering getting a new drive for this endeavor, here's what I suggest:
- Get a drive that's at least 1-2TB in space, preferably 4TB. With the iPhone able to save 4K video, our space needs aren't shrinking anytime soon: The bigger hard drive you can afford, the better.
- If you're buying a stationary hard drive, buying a disc-based hard drive is great, but buy good brands — don't try and save $50 on an off-brand hard drive. It's rarely worth the HDD failure.
- If you're buying a portable hard drive, consider SSD: It's very pricey in comparison to a disc-based drive, but if you know you'll be frequently moving around — especially if you plan to move around with the drive connected — you want a drive that can take a little rumble and tumble without skipping or failing.
- Hard drive speeds are important, too: The faster a drive's write speed, the quicker your images will copy; the faster a drive's read speed, the easier it will be for you to view images or video and edit them, too.
Want some recommendations for specific external hard drives? We've got those, too.

How to move your current Photos library to an external drive and use it as your primary library
As with creating a new library, moving your library to your external drive is a multi-step process. Here's how to go about it.
Step 1: Copy over your Photos library
- Connect an external drive to your Mac via USB, USB-C, or Thunderbolt.
- Open a new Finder window.
- Open your external drive in that window.
Open a new Finder window. Don't close your previous window (open to your external drive), as you'll need it shortly.
- Click the Go menu and navigate to your Home folder.
- Select the Pictures folder.
- Select your old library.
Drag it to your external drive in the other Finder window.
Your library will begin to copy over to your external drive. Depending on the size of your library and speed of your drive, this can take anywhere from a few minutes to several hours, so be patient. Don't unplug your drive or turn off your computer during this process.
Step 2 (if you use iCloud): Turn off iCloud sync on your old library
Open Iphoto Library
Before you open your copied Photos library on the external drive, you have to disassociate the library on your Mac from iCloud. (If you don't use iCloud Photo Library, you can skip these steps.)
- Open Photos on your Mac.
- Go to the Photos menu.
- Select Preferences.
- Click on the iCloud tab.
Uncheck iCloud Photo Library.
- Press Remove from Mac to remove any undownloaded low-resolution items from this library.
Quit Photos.
Step 3: Make your new library your system default
Now, it's time to make your newly-copied Photos library your system default.
- Open Photos on your Mac.
- Go to the Photos menu.
- Select Preferences.
Click Use as System Photo Library.
Step 4 (if you use iCloud): Connect your new library to iCloud
Your external library is now set up to be your system default, but it's not currently connected to iCloud. If you use iCloud Photo Library and want to keep that connection active so that you can continually download items you've stored, read on. (Otherwise, you can skip this step.)
- Open Photos on your Mac.
- Go to the Photos menu.
- Select Preferences.
Click on the iCloud tab.
- Check iCloud Photo Library.
- Click Download Originals to this Mac.
- Wait for your Mac to download your images from iCloud. (Depending on the size of your iCloud library and your internet connection, this may take up to 24 hours; don't disconnect your external drive or turn off your Mac during this time.)
Once your library has fully synced and downloaded images, you can disconnect your drive; whenever you want to use your Photos library, you now need to connect your drive to your Mac.
Step 5: Get rid of your old library
A personal plea: Please, please, please make sure your library is fully copied and working on your external drive before you follow the steps below — once you've thrown away your original library, it's gone!
- Open a new Finder window.
- Click the Go menu and navigate to your Home folder.
- Select the Pictures folder.
Select your old library.
- Drag it to the Trash (or press Command-Delete on your keyboard).
- Empty the Trash.
- Open a new Finder window. Don't close your previous window (open to the Pictures folder), as you'll need it later.
- Select your external drive.
- Right-click (or control-click) on your copied Photos library on your external drive.
- Select Make Alias.
- Drag the alias to the Pictures folder.
Rename the alias to remove the 'alias' part of its name.
Now you have a direct link to your copied Photos library from the Pictures folder: This prevents your computer from accidentally creating multiple Photos libraries in case you forget to launch Photos with your external drive connected.
Note: If you're worried about accidentally creating libraries, you can always launch Photos by option-clicking on its icon in the Dock or Applications folder; this will give you the option of picking which library you'd like to launch.
How to create a new Photos library on your external drive and use it as your primary library
Creating a new library on your external drive is a multi-step process. Here's how to go about it.
Step 1 (if you use iCloud): Turn off iCloud sync on your old library

- Select Preferences.
Click on the iCloud tab.
- Uncheck iCloud Photo Library.
- Press Remove from Mac to remove all low-resolution items from this library.
- Press Remove from Mac once more to confirm.
Quit Photos.
Step 2: Create your new Photos library
Once you've done this, it's time to create a new library.
- Connect an external drive to your Mac via USB, USB-C, or Thunderbolt.
- Option-click (and continue holding down option) when launching the Photos app on your Mac.
- When it asks you to choose a library, click on Create New….
Name your library.
- Press the Down arrow to expand the File picker and choose your external drive as the new location.
- Press OK to save it to your external drive.
Step 3: Make your new library your system default
You'll now have an empty library on your external drive. Next up: Making it your system library.
- Open Photos on your Mac.
- Go to the Photos menu.
- Select Preferences.
Click Use as System Photo Library.
Step 4 (if you use iCloud): Connect your new library to iCloud
Your external library has now been set up from scratch. If you use iCloud Photo Library and want to download all the items you've stored there to have an external backup, read on. (Otherwise, you can skip this step.)
- Open Photos on your Mac.
- Go to the Photos menu.
- Select Preferences.
Click on the iCloud tab.
- Check iCloud Photo Library.
- Click Download Originals to this Mac.
- Wait for your Mac to download your images from iCloud. (Depending on the size of your library and your internet connection, this may take up to 24 hours; don't disconnect your external drive or turn off your Mac during this time.)

Step 5: Get rid of your old library
A personal plea: Please, please, please make sure your new library is live and working on your external drive before you follow the steps below — once you've thrown away your original library, it's gone!
- Open a new Finder window.
- Click the Go menu and navigate to your Home folder.
- Select the Pictures folder.
Select your old library.
- Drag it to the Trash (or press Command-Delete on your keyboard).
- Empty the Trash.
- Open a new Finder window. Don't close your previous window (open to the Pictures folder), as you'll need it later.
- Select your external drive.
- Right-click (or control-click) on your new Photos library.
Select Make Alias.

For all your USB-C needsThe HybridDrive is a USB-C dock with an SSD built in
You need more ports, right? And you probably need more storage, right? What you really need is the HybridDrive.
Photos in macOS Catalina has an immersive, dynamic look that showcases your best photos. Find the shots you’re looking for with powerful search options. Organize your collection into albums, or keep your photos organized automatically with smart albums. Perfect your images with intuitive built-in editing tools, or use your favorite photos apps. And with iCloud Photos, you can keep all your photos and videos stored in iCloud and up to date on your Mac, Apple TV, iPhone, iPad, and even your PC.
A smarter way to find your favorites.
Photos in macOS Catalina intelligently declutters and curates your photos and videos — so you can easily see your best memories.
Focus on your best shots.
Photos emphasizes the best shots in your library, hiding duplicates, receipts, and screenshots. Days, Months, and Years views organize your photos by when they were taken. Your best shots are highlighted with larger previews, and Live Photos and videos play automatically, bringing your library to life. Photos also highlights important moments like birthdays, anniversaries, and trips in the Months and Years views.
Your memories. Now playing.
Memories finds your best photos and videos and weaves them together into a memorable movie — complete with theme music, titles, and cinematic transitions — that you can personalize and share. So you can enjoy a curated collection of your trips, holidays, friends, family, pets, and more. And when you use iCloud Photos, all edits automatically sync to your other devices.
The moment you’re looking for, always at hand.
With Search, you can look for photos based on who’s in them or what’s in them — like strawberries or sunsets. Or combine search terms, like “beach 2017.” If you’re looking for photos you imported a couple of months ago, use the expanded import history to look back at each batch in chronological order. And in the My Albums tab, you’ll find your videos, selfies, panoramas, and other media types automatically organized into separate albums.
Fill your library, not your device.
iCloud Photos can help you make the most of the space on your Mac. When you choose “Optimize Mac Storage,” all your full‑resolution photos and videos are stored in iCloud in their original formats, with storage-saving versions kept on your Mac as space is needed. You can also optimize storage on your iPhone, iPad, and iPod touch, so you can access more photos and videos than ever before. You get 5GB of free storage in iCloud — and as your library grows, you have the option to choose a plan for up to 2TB.
Make an edit here, see it there. When you make changes on your Mac like editing a photo, marking a Favorite, or adding to an album, they’re kept up to date on your iPhone, your iPad, and iCloud.com. And vice versa — any changes made on your iOS or iPadOS devices are automatically reflected on your Mac.

All your photos on all your devices. iCloud Photos gives you access to your entire Mac photo and video library from all your devices. If you shoot a snapshot, slo-mo, or selfie on your iPhone, it’s automatically added to iCloud Photos — so it appears on your Mac, iOS and iPadOS devices, Apple TV, iCloud.com, and your PC. Even the photos and videos imported from your DSLR, GoPro, or drone to your Mac appear on all your iCloud Photos–enabled devices. And since your collection is organized the same way across your Apple devices, navigating your library always feels familiar.
