No you cannot sync an iPhoto library between two macs. If you do you will corrupt the iPhoto Library file. IPhoto is a consumer level app, and this feature is not supported. What you can do is share the photos but not the library. Each machine will need to have it's own library file. (Even before shared libraries, I had this feature enabled as a painless way to backup my iPhone photos.) Set up a shared library. To share your library or part of it with someone, open Google.

Jan 06, 2014 I want to share a single iPhoto library between two Mac computers. I would like to store the iPhoto library on the network because both Macs may not be connected at the same time.After reading the article Save Space On Your Mac By Storing iPhoto & iTunes Libraries Remotely Save Space On Your Mac By …. Dec 26, 2019  I have a Photos library on an external drive (both the photos and the.photoslibrary file). It contains scans of photos ranging from 40-60 years old. I'd been ID'ing the people in it with the help of my mother (who's 89) and to to do so I'd set up one of my old Macs for her (well, really for me, since she doesn't use computers).

I've had a multi-Mac household pretty much since college, rocking a laptop and desktop in addition to miscellaneous iOS devices throughout the years. Dropbox and iCloud sync made most of the pains of using several Macs disappear, but iPhoto was always a problem. My laptop is tiny! My iPhoto library, not so much.

Thankfully, Photos for Mac — paired with iCloud Photo Library's Optimize Storage feature — makes working with and syncing multiple Macs a breeze. Here's how you can do it.

How to use Photos and iCloud Photo Library with multiple Macs

Here's a quick, simple breakdown on setting up your Macs to support Photos and iCloud Photo Library.

I recommend starting with your biggest iPhoto library; it'll usually be on your desktop Mac. When you open Photos for the first time, your library should import automatically; if it prompts you to create a new library, your Photos library may be stored in another location on your Mac, and you may need to manually open it.

Once you've imported your biggest library on your Mac, make sure iCloud Photo Library is turned on and syncing. You can do this by following these steps:

1. Launch Photos on your Mac.
2. Click Photos in the menu bar.

3. Select Preferences (or do this quicker by pressing ⌘,).

4. Click on the iCloud tab.

5. Check off the box for iCloud Photos.

   Where is my Mac’s Library folder?Prior to Mac OS X Lion’s release back in 2011, if you wanted to access the Library folder you could just open your Home folder and view the Library folder there. There are actually three Library folders on the Mac.The Library folder you can see contains files that are accessible to all users but only changeable by administrators. That folder is still located in Home, but it’s now hidden.You may have just looked in your Macintosh HD folder and thought you saw the Library folder, but that’s not the Library folder in question. Mac show hidden files library. You might feel confident that you know what you’re doing on your Mac, but there are plenty of Mac users who could cause damage or data loss if they were able to mess with files in the Library, for example.

   • You can also check off the box for Download Originals to this Mac if you have the space.
   • You can check off Optimize Mac Storage to save space on your Mac by only saving a percentage of images and video locally — the rest will be thumbnails that you can click on to download when you want to.

Now, open your other Mac, and launch Photos. If you have an iPhoto library on that secondary Mac, follow the same steps as above — import your library, then turn on iCloud Photo Library. If you have duplicates of the same photo on each computer, iCloud should automatically resolve those conflicts when it syncs, providing you with just one version of your photos when the sync process finishes.

If you don't have an iPhoto library on your secondary Mac, create a new library in Photos and turn on iCloud Photo Library. If you want to save storage space on this secondary Mac, make sure Optimize Mac Storage is selected: This will save a certain percentage of images and video locally to your device, while providing thumbnails of all the others for you to download at your leisure.

After you've set up all your Macs with Photos and the sync process has finished, you're now good to go. From here on out, any time you add photos, they'll sync to every computer you've set up with Photos.

What syncs, what doesn't sync

Photos for Mac syncs a lot more than just your original photos and videos. According to a support document on Apple.com, here's what else you should expect to see sync:

• All folders and albums
• Smart Albums
• Keywords
• Memories
• Searchable keywords
• Key photo selections

There are a few things iCloud Photo Library won't sync, however. Here's Apple's list:

• Books, cards, calendars, and slideshows
• Keyword shortcuts
• Unused keywords
• Last imported album on the Mac in question
• Names and faces in the People album

For those not using iCloud Photo Library

If you've chosen not to enable iCloud Photo Library, Apple still offers you free syncing of your last 1000 photos via My Photo Stream, which doesn't count toward your iCloud disk space.

This will sync and download images you've imported or taken on other devices, but you won't have the option to optimize your storage or sync your albums.

Anker's PowerCore Wireless 10K charger is a battery pack without the fuss

Anker is out with a new wireless battery pack that'll keep things ticking along no matter where you are.

We take a lot of photos with our iPhones and even DSLRs and other cameras. Photos are great for capturing memories with others, or when you just want to get a snapshot of something beautiful. Photos on Mac can help you keep all of your photos in one place, and even help you organize them.

How to add pictures and videos to albums

If you have a lot of photos and videos, one of the simplest and easiest ways to start organizing everything is to make use of albums, especially when you give them good names. And if you use iCloud Photo Library, all of your albums in Photos for Mac get synced to your iOS devices too.

1. Launch Photos on your Mac.

2. Click on Photos in the sidebar, under the Library section.

3. Pick out the photos you want to add to an album, either new or existing.

   • Hold down the command key on your Mac and click to select multiple photos.
4. Right-click on your chosen photos and videos.
5. Move the cursor to Add to.

6. You can choose an existing album, or create new album.

   • If making a new album, give it a good, easy-to-remember name.

Optionally, you can make a new album at any time by clicking the + button that appears in the sidebar next to My Albums. Drag-and-drop the albums in whatever order you want to rearrange them in the sidebar.

How to organize albums and folders

When you have a lot of albums, it may be better to clean it all up by organizing albums into folders, which are like collections of albums. It's easy to do.

1. Launch Photos on your Mac.

2. Either right-click on My Albums in the sidebar, or hover above and then click on the + button that appears next to My Albums.

3. Click New Folder.

4. Give your folder a name.

5. Drag the albums that you want into that folder.

How to use Smart Albums

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.

1. Launch Photos on your Mac.

2. Right-click on My Albums or click the + button that appears next to My Albums.

3. Select New Smart Album.
4. Give your Smart Album a name.

5. Choose the parameters for your Smart Album.

6. Click OK to confirm.

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.

If you're not satisfied with the Smart Album, you can always tweak the settings by clicking on the gear icon that's next to the Smart Album's title, then re-select the parameters you want to use.

Unfortunately, Smart Albums do not sync to your other devices through iCloud Photo Library, as they're only available on your Mac.

How to navigate Photos for Mac faster with the sidebar

The Sidebar in Photos is a great way to quickly jump between various areas in Photos quickly and easily. Plus, it helps you find albums that may otherwise be hidden, so this was a design choice made by Apple.

However, if you are running macOS Sierra and older, you can actually hide or unhide the sidebar as you wish.

1. Launch Photos on your Mac.
2. Click on View in the menu bar.
3. Select Show Sidebar in the menu.
4. The sidebar will appear on the left side of the screen.

5. Follow the steps above to hide it (make sure Show Sidebar is unchecked).

How to navigate moments, collections, and year views in macOS Mojave and earlier

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

This means that your photos appear in a timeline and are grouped by things like location, or even event. It's a great way to take a look back at your memories and relive those specific moments in time.

The Moments, Collections, and Year views are only available in macOS Mojave and older.

1. Launch Photos on your Mac.
2. Make sure that you're in the Photos view from the sidebar.

3. Click on Photos, Moments, Collections, or Years buttons at the top of the window.

4. Click on a section of a Year to move to that Collection, or a section of a Collection to drill down into that Moment, or an item in a Moment to view that image or video in closer detail.

5. You can also use your keyboard's arrow keys to move between photos and videos in a Moment.

6. A single click on an item selects it, while a double click takes you to view it.

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 navigate through Years, Months, and Days in macOS Catalina

To replace the previous Moments/Collections/Years view, Catalina changed it to Years, Months, and Days for simplicity.

1. Launch Photos on your Mac.

2. Make sure you're in the Photos section in the sidebar.

3. Click the Years, Months, or Days buttons at the top of the window. The default view is All Photos. How to sync itunes library on 2 macs.

4. Clicking on Years lets you see each year as a block. Double-clicking the year takes you into Months.

5. When you double-click on a Month, you'll drill down into the Days view.

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.

1. Hold down the Option key on your keyboard.
2. Double-click on Photos on your Mac.
3. Click on the Create New button in the Choose Library window.
4. Name your Library.

5. Click OK.

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 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.

1. Make sure that Photos is not open (quit if it is).
2. Hold down the Option key on your keyboard.
3. Double-click on Photos.

4. Click on the name of the library you want to open.

Voilá! Just make sure to repeat this process each time you want to switch to a different Photo library.

How to move your Photos library to an external hard drive

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.

1. Launch a Finder window on your Mac.
2. Click on the Mac hard drive (Macintosh HD) in the sidebar.
3. Double-click on the Users folder.
4. Double-click on your username.
5. Double-click on your Pictures folder.

6. Click on the Photos Library file and then drag it to your external hard drive in the sidebar.

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.

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.
