I got a little question I guess its easy for you to answer. I have a MacBook 17 (old one) with MacOSX 10.11 on it. And since the latest update they renamed iPhoto to Photos. So in my Pictures I do have now a iPhotos Library with 154GB (which has been untouch since the update) and I got a Photos Library with 204GB (which has been active all the time and I guess also because of that grown).
Can I delete the iPhoto library to get more space? Or do I need them both? Is there a way to check?
edit:// I attached the picture of both libraries next to each other
Thanks for your help
