I have heard that Yosemite will do away with iPhoto. Does that mean that all of the photos I currently have on iPhoto will be lost?? How will the new Photo App work? Thanks, Maria
Yep. Well, no; Apple’s doing away with it, regardless of OS.
‘Course not. Your iPhoto/Aperture library will be upgraded to a Photos library when the software starts existing.
Well, here’s iOS 8’s bit on it, but that hardly covers what the desktop version will be.
