I have been trying for nearly an hour trying to get Photostream to show in iPhoto on my iMac. My iPhone/iPad/Apple TV all show the Photostream fine and new pictures appear instantly. The account is exactly the same, and reticking the photostream option in the options deletes and downloads the pictures, as it states it's downloading them: But after it's finished nothing appears: I added an image to the photostream directly from the none-working iPhoto and this does not show on the working devices. If anyone has any advice, any magical file I need to delete or move to get this to work, please say. NOTE: I have updated everything and checked all the account names and passwords. And I have tried searching for the answer, but what I have found only states really how to set it up and resync everything which isn't really the problem.
