It’s actually really nice! Having only used it for one day now I would say it miles better then iPhoto. It’s so much cleaner and looks just like the IOS version. When I first lunched Photos I instantly knew what to do since it just like the IOS version, which is a good thing in many way.
When it started to upload my Photos to the Photos application, I went to preferences and went to the iCloud tab at the top of the preferences page and I noticed that theirs quite a bit of options that actually make it better for you mac.
The first option was “iCloud Photo Library (Beta)” and what that does is “Automatically upload and store your entire library in iCloud to access photos and videos from all your Apple devices or on the web.” Which is really nice so you can go to your iPhone, iPad, Mac, iPod, or even from the web and access your photos and videos from there.
The second option you get is “Download Originals to this mac” which Stores original photos and videos on your Mac. This option is great so if your Mac is offline you can access full-resolution versions of your Photos/Videos.
The third option I like a whole bunch and it’s “Optimize Mac Storage” which Stores full-resolution photos/videos in iCloud. Originals will be stored on your mac if you have enough Storage space.
The Fourth and fifth option you get is is “My Photo Stream” and “iCloud photo Sharing” are basically what they say. “My Photo Stream” is where when you import recent photos for devices without having iCloud Photo Library. “iCloud photo Sharing” is when you create albums with other people, or subscribe to other people’s shared albums.
Now that was only the options. As you can tell Apple has done a great job to optimize Photos for your mac in every which way! For an only 1-day user I give it an 9 out of 10.
