Maybe I missed this, but when I installed Yosemite on my computer, photo stream stopped working in iPhoto. I try to click enable through the app and the app slows down to a crawl and then times out and crashes. And after I quit out or it quits out by itself, I could no longer open the iPhoto library. It would crash iPhoto upon opening. I eventually had to take the master folder out of the library file and create a new library. Anyone else having this issue or problem?
