Discontinued by Apple and replaced with Apple Photos

This was the best photo cataloguing software for Mac. It is a pity Apple replaced it with Photos, which gives you just a pile of photos.
iPhoto is always incredibly slow to launch, the app itself is way larger in size than it should be, and the libraries that it creates are completely nonsensical to navigate from Finder. Nevertheless, iPhoto has the best user interface of any photo management app I've seen so far. So I'll allow it.
