I have used the search feature and can't find the answer to my question, but I its been asked and answered I'm sorry to ask again! Can I delete the new photos app on my macbook pro and use my old iPhoto? I need to get things moved around in iPhoto and then try the new photos app. I know I can still use iPhoto but I want to remove the new photos app so I don't have two of everything. I am having a terrible time with this new photos app, I had all my photos organized in Events then broken down into albums by date or occasion. That worked great for me and now in photos everything is out of order and the newer photos that I had yet to sort are mixed in with everything else and I can't seem to merge or add the events. I hate this new app! And at the very least I would like to go back to my iPhotos and get everything where I want it then back it up to a external hd. I would like to delete the new Photos file and when I decide to try it again start from scratch with a clean slate. Photos has duplicated so many of my photos it crazy.
