I reformatted my computer and set it up as a new machine, and I am having trouble getting my photos to work right. I copied over my old photo library to the newly set up machine, but can't find a way to point it to iCloud. When I turn on iCloud, it tries to upload everything to iCloud, not recognizing that it is already there. This is a problem because my library is HUGE and it took days/ weeks to do it last time. I also tried starting fresh and downloading all my photos from iCloud (my download speed is way better than my upload speed so this was much more doable). The problem is that once it finishes downloading them, all of a sudden it says it needs to download them all again, and it hasn't moved in days. Do you guys have any suggestions of how to get my photos to play nice with iCloud again?
