I have a second user account on my machine that is only used for iCloud syncing for my wife's apple id. In order to consolidate photostream photos I'm going to set up a process to pull new photos out of her photostream folder and import them into my iPhoto library.
But first, I have to alter permissions so I can see her photos from my user account. I've managed to set the permissions for the "everyone" user to see the photos from my user account, and that works for existing photos. But when new photos come in, they are set where only her account can see them.
Here is what I'm using. Hopefully someone can tell me what I'm missing. :-)
sudo chmod -R +a "everyone allow read,write,execute,append,readattr,readextattr,readsecurity,writesecurity,file_inherit,directory_inherit" '/Users/Wife/Library/Application Support/iLifeAssetManagement/assets/sub'
