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:
Launch Photos on your Mac.
Click Photos in the menu bar.
Select Preferences (or do this quicker by pressing ⌘,).

Click on the iCloud tab.

Check off the box for iCloud Photos.
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.

If you want your Mac's photos to wirelessly sync to all your other iOS devices and computers, you want to set up iCloud Photo Library: Apple's photo sync service lets you back up your images on all your devices, as well as access them — online or offline — on said devices. If you're willing to pay for the extra iCloud storage space, you can store an incredible amount of photos and videos, all accessible at the touch of a button or multi-touch screen.
Here's how to set it up on your Mac and get everything configured to your liking!

How to optimize your photo and video storage
Mac Photo Library Management
If you routinely shoot 4K video or high-quality images on your iPhone, iPad, or DSLR, you may run out of storage space fast. (I have a 1TB iMac, but also have almost a terabyte of 4K video stored in iCloud — it gets unwieldy, fast!) This is especially true if you have a Mac laptop with limited hard drive space: It's nice to look at your iPhone's gorgeous Portrait mode photos, but not necessarily always practical to store all of them locally.
Access Mac Photos Library Pc App
Thankfully, Apple offers an Optimize Storage option, which lets you store full-resolution photos and videos of only your most recently shot and accessed imagery; all older photos and videos are available to download via iCloud and are stored as low-resolution previews on your device to save space. You can switch between optimizing your Mac's photos storage or storing your full library locally: Here's how!
Note: If you plan on using Optimize Storage, we suggest having at least one device that stores your entire library locally (usually a Mac with a large local or external hard drive), so you have multiple backups of your photographs and video.
Launch the Photos app on your Mac.
Click Photos in the App menu in the upper left corner of your screen.
Select Preferences from the drop-down menu.

Full-resolution versions of your photos and videos will be uploaded to iCloud.
How to share photos with iCloud Photo Library
Apple's photo service doesn't just provide online backups and sync for your images and video: The company also offers a free sharing service that allows you to send shared albums to friends and family (or create a publicly-shared website). Here's how to turn it on for your Mac.
