There seems to be a lot of confusion out there about this. I know that Apple is discontinuing the *development* of Aperture once Yosemite is released. Typically a program will still work when you upgrade your operating system -- for example, when I upgraded from Mountain Lion to Mavericks, my Office 2011 continued to work -- but I have heard that in this case, Aperture won't work AT ALL under Yosemite -- something to do with Yosemite lacking iPhoto components that Aperture needs in order to even function. In other words, what I am hearing is that Aperture simply will not run under Yosemite. So I will ask a simple question which should have a simple answer: Will the current version of Aperture run -- or will it fail with an error -- when a machine is upgraded from Mavericks from Yosemite?
