Is the 'Importing: Copy items to the Photos Library' active? If not, deleting photos will not reduce the library size much, since the original photos are stored outside the library and will not be deleted, when you delete photos. To check for referenced files, create a smart album with the rule 'Photo is Referenced'. Are there photos on this album?

With the upgrade to Photos, many Mac users have been left with a duplicate iPhoto library on their Macs. Here’s how to delete iPhoto library and clear out some clutter.
iPhoto used to be the standard photo editor and photo management system on Macs, at least for the average computer user. Like it or not, however, that all changed when Apple first introduced the software, nearly a year ago. If your Mac came from Apple with Photos already installed, you don’t need to worry about old iPhoto libraries.
A Mac that was upgraded to a new version of OS X that added the Photos app, however, can end up with what look like duplicates of their photo libraries. The first time you start up Photos after upgrading, your Mac will copy over your photo library into the new software (if you explicitly set up more than one old iPhoto library, you’ll have to copy them over yourself). It doesn’t go back and delete the old one, though. Mac hiw to access final cut pro library.
Here’s where things get a little bit confusing: you don’t actually have two copies of your photos. Thanks to the way OS X (the software that powers your Mac, like Windows powers a PC) works, your pictures aren’t actually stored in those libraries. Instead, they’re stored somewhere else on your hard drive, and each library has what Apple calls a “hard link” to the pictures. As a result, each library can access the photos, but store separate information about them. You can delete either library safely; only if you were to delete both libraries would you lose access to your pictures.
While having a second copy of your photo library doesn’t take up that much extra space on your computer, it can still be confusing – first of all, each library reports that it’s a certain size, which can make it difficult to figure out how much room is left on your Mac. Additionally, if you need to back things up, it can be hard to figure out where your files are.
Still with us? Let’s recap:
- if you upgrade your Mac from iPhoto to Photos, you’ll get a second photo library
- if you had multiple iPhoto libraries (you would know if you did), you’ll need to copy them into Photos manually
- the libraries each link to a single copy of your photos, rather than storing each photo twice
- it can appear that your libraries are taking up more space than they are, thanks to the way hard links work
- you can safely delete either photo library – only if you delete both of them will you lose access to your photos
How to delete iPhoto library on your Mac
Now that you understand why you might want to delete an old iPhoto library, and why you don’t necessarily have to, let’s talk about how to actually do it.
Before you do anything like this on your Mac – that is, delete something potentially important – you should back up your software with something like Time Machine.

That way, if you accidentally delete something important, or something else goes wrong, you can always roll things back to how they were when you started. This is really easy, and there’s nothing to be concerned about; it’s just good practice to back things up (and keep them backed up) before you muck about in your computer.
First, you’ll need to open a Finder window: you can do this by clicking on the Finder icon (it looks like a square face) on the dock, or by clicking on your Mac’s desktop background and hitting ⌘+N (Command + N) on your keyboard.

Next, look at the left-hand column in the new window. You’ll see a list of locations around your Mac; find the one that says Pictures and click on it. You’ll be taken to that directory, which contains libraries for Apple’s image-related apps (Photos, iPhoto, Photo Booth, etc).
In the list of files on the right, scroll down and look for your iPhoto library – it’ll be a little iPhoto icon, and the name will read, unsurprisingly, iPhoto Library. Don’t worry about accidentally deleting your Photo Booth or Photos libraries; you’ll be able to see which one is which.
To actually delete the library, you can do one of three things:
- Click on the iPhoto Library listing, and without letting go of your mouse or trackpad button, drag it until it’s over top the Trash icon on your dock. Once you’re on top of the Trash, let go.
- You can select (click on) the iPhoto Library, then right-click on your mouse or Trackpad (Apple will call this Secondary Click in your Mouse or Trackpad settings). A new menu will pop up; find the entry that says Move to Trash and click on it.
- Finally, you can also delete your iPhoto Library by clicking on it and hitting ⌘+Delete (Command + Delete) on your keyboard.

Now that you’ve gotten rid of your iPhoto library, it makes sense to completely uninstall iPhoto – that way you won’t accidentally create a new iPhoto Library and have to repeat all these steps. It’s as simple as opening up your Applications folder, and deleting iPhoto (using one of the three steps we just discussed).

Photos in your System Photo Library are available in apps like iMovie, Pages, and Keynote. You can also sync them to iOS devices and view them on Apple TV. And if you want to use your own images as your desktop picture or screen saver, the images need to be in your System Photo Library before you can select them in System Preferences.
If you have only one photo library, then it's the System Photo Library. Otherwise, the first photo library that you create or open in Photos will become the System Photo Library. If you have more than one library, you might need to designate a System Photo Library, so other apps can access the photos and videos you want them to use.
Follow these steps to designate a System Photo Library:
- Quit Photos.
- Hold down the Option key and open Photos. One of the photo libraries is already designated as YourLibraryName (System Photo Library).
- Choose the library you want to designate as the System Photo Library.
- After Photos opens the library, choose Photos > Preferences from the menu bar.
- Click the General tab.
- Click the Use as System Photo Library button.
If you open a second or different library in the Photos app, and you haven't designated it as the System Photo Library, other applications will use photos from the original System Photo Library. Hold down the Option key when you open Photos to see which library is set as the System Photo Library.

iCloud and the System Photo Library
You can use iCloud Photos, Shared Albums, and My Photo Stream only with the System Photo Library. If you choose a different library in Photos without designating it as the System Photo Library, the iCloud tab in Photos preferences is disabled:

If you designate a new library as the System Photo Library and then turn on iCloud Photos, the photos and videos in the new library will merge with those already in your iCloud Photos. If you want to keep the contents of your photo libraries separate, don’t turn on iCloud Photos for more than one library in Photos.
