With the Yosemite Public beta, I transitioned my iPhoto Library over to the Photos app, and it uploaded all my photos to my iCloud storage. After playing around with it for a day, I decided I don't want all my photos accessible in iCloud, and want to configure it a slightly different way. Essentially, I want to start over. I followed the directions in this document, but it didn't work. I removed my Photo library, and it disappeared from my iCloud storage allocation. But when I turn iCloud syncing back on (either on my iPhone or Mac), it starts syncing all the photos again. How can I remove these permanently?
