Here’s where things get a little bit confusing: you don’t actually have two copies of your photos. It doesn’t go back and delete the old one, though. 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). 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.Ī 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.

IPhoto used to be the standard photo editor and photo management system on Macs, at least for the average computer user.

Here’s how to delete iPhoto library and clear out some clutter. With the upgrade to Photos, many Mac users have been left with a duplicate iPhoto library on their Macs.
