One of the most convenient features of iCloud is the ability to sync, share, and view photos between multiple Apple devices using the iCloud Photo Library. Introduced with OS X Yosemite, iCloud Photo Library makes taking photos on your iPhone (using iOS 8.3 or later) and viewing or editing them on your Mac or iPad, a seamless transition.
Makes sure that you’re signed into the same Apple ID on all the devices you wish to sync, that you’re connected to Wi-Fi, and that you’re not running on low battery power. Check, check, and check? Great- lets dive into turning on and efficiently using iCloud Photo Library.
On your iPhone or iPad:
That’s it! Now all your photos and videos will be accessible across all of your Apple devices. It might take a while for your photos to all upload, which could affect your computer's performance. If it’s becoming a problem, you can always pause for one day to allow for a better user experience on your Mac.
To Maximize the storage space on your devices, Apple introduced an “optimized storage” function that puts your favorite or recent pictures on the device itself and sets older ones to be stored to iCloud. Essentially, it allows you to keep you most important images on your iPhone, Mac, or iPad and stores less relevant images to your iCloud.
