Hi, I have moved all the iLife apps into a separate iLife folder within the Applications folder. This apparently caused problems with the latest iPhoto update (9.1.2). iPhoto said there's a new update, but Software Update said there isn't. Even after I downloaded the update manually from the Apple website it refused to install it, saying that iPhoto 9.1 is required to install the update. The update did only install after I moved the iPhoto back to the Application folder (out of the sub folder). Is this a general problem? Does moving apps cause the System Update to fail? I have moved many apps, including iLife and other apps that came with Snow Leopard into other sub-folders. Do they all need to stay in the main Applications folder? If so, then I think the Applications folder becomes overcrowded quite quickly. Are there other negative side effects of moving apps?
