The Photos app first became a part of the OS X in Yosemite update (version 10.10.3) released on April 8, 2015. It replaced the older iPhoto that was presented in 2002 and successfully operated ever since. If you have a newer Apple computer, you probably haven`t heard about iPhoto and only have Photos library on your Mac. But if you upgraded from earlier Mac OS version, you may wonder why you have both iPhoto and Photos libraries. Let`s try to figure it out.

Will iPhoto App Disappear if I Update to OS X Yosemite v10.10.3?

When you update to OS X Yosemite v10.10.3 or later macOS, you get the all-new Photos. It becomes your default app for photo editing, but iPhoto remains accessible in the Applications folder. To launch it, go to Finder -> Applications folder, and click on the iPhoto icon. When you open iPhoto app after you`ve upgraded to Photos, you`ll be asked which application you want to use to open the library – Photos or iPhoto.

What If I Want to Continue Using iPhoto?

If you`re iPhoto addicted, you can continue to use this app after the system update. But note that Apple is not going to improve iPhoto anymore. All you have now in this application is the final version, and it`ll never be changed to keep up with time. In its turn, the Photos app is quite adaptive to user`s needs and not aggressive towards your older app. You`ll be able to use the same photo libraries but get all-new opportunities.

What Will Happen When I Open the Photos App on My Mac?

If you have a single iPhoto library, its content automatically migrates to Photos when you first open it. Pictures folder becomes the default location for your new Photos library.

Pictures Folder

When it happens, two photo libraries appear in the Pictures Folder – one from iPhoto and one from Photo apps. Don`t worry: your new photo library doesn`t duplicate your images. But read how to delete iPhoto duplicates for your nformation. It creates links to the original versions of your photos, thus saving your disk space.

the Photos library

When Finder shows the size of the Photos library, it also includes your previews and original files. You may think that the remaining iPhoto is eating up twice the space, but it isn`t so. All your master files exist in one location though you have more than one photo library on your Mac. Because it takes little additional space on the hard drive, you don`t need to delete the original photo library.

What if I Have More than One Photo Library?

If there is more than one photo library, Photos will ask you which one you want to migrate. The new app lets you work with different libraries you created in iPhoto. If you wish to relocate another photo library, do it manually:

Choose Library

If you haven`t found the library in the list, click on the Other Library button, identify the library you need, and then click Open.

The Photos app also lets you drag the library you need to the Photos icon in the Dock panel or click on the Create New button to create an empty library.

Are All Edits Applicable to All Photo Libraries?

All changes you do in iPhoto, including photo editing, album changes, and others, remain visible only in this app. The same goes for changes made in the Photos app – they won`t be reflected in iPhoto.

What Else Should I Know About iPhoto and Photos Coexistence?

The new Photos app turns Events from iPhoto into albums. You can find them in the iPhoto Events folder available in the Albums view.

Flags, star ratings, and other metadata once available in iPhoto will be turned into the keyword to make your search more convenient.

Two Photo Libraries is No Way a Problem!

The appearance of Photos as a part of new system update explains why you have two photo libraries on your Mac. But it`s no way a problem since it doesn`t eat up twice the space. So, you don`t have to delete your original photo library if you`ve decided to say goodbye to iPhoto.
