iPhoto vs photos what's the difference

Photos is the relatively new photo managing app. iPhoto was the app that came with iLife that was discontinued, though it still works fine. Where are you seeing this error?

Main difference is that iPhoto is dead all support having been discontinues nearly two years ago and print products having been discontinued about six months ago and Photos is the current Photos manage software included with all Macs and is fully supported

Have you migrated your iPhoto library to Photos ?

This is extremely frustrating to me. I simply don't like Photos. I have been using basically the same Mac since 2001 (just buying new hardware and then migrating the data). I have spends untold hours organizing iPhoto to exactly the way I want it, and now Apple has decided that we should be using Photos. I don't mean this to be a bashing session, but why does Apple keep changing software (iTunes, iMovie) to the point where they are bloatware and just too frustrating to use.

I ask out of ignorance, does Photos have Events, Albums, Faces? Do I just lose all of that if I go with Photos? And to me the UI is just plain ugly.

Photos has albums, smart albums, folders, People (a newer version of faces), Places. There are no events in the original form, instead Photos has Moments, collections, years. These are created automatically, based on the capture date and the location of the photo.

When you migrate from iPhoto your albums, keywords, titles, captions will be migrated, and your events will be recreated as albums, so the names of the events will be saved.
