Fakhar is having issues with iPhoto. Leo says that Apple has replaced iPhoto with Photos in OS X Yosemite. Fakhar says that happened to him and he lost a lot of features and slide shows. Leo says that many of the features that iPhoto had are missing, while some are still there but aren't as apparent. Apple has written it from the ground up and will likely re-add those missing features as time goes on. Face recognition is still there, but it's harder to locate within albums. Leo advises patience. Unfortunately, that's the world of Apple. It's their way or the highway.
