The rollout of iCloud photo library seems REALLY heavyhanded. It works perfectly fine on iOS devices, but on Macs they've left us high and dry.
As far as I can tell, until Photos ships in 2015, the only way to get to iCloud Photo Library on Mac is to go to iCloud.com. It baffles me how they shipped two OSs but didn't build in a way to sync photos between them. At least issue a patch for iPhoto or something!
What really bugs me about iCloud Photo Library from the website is that it's gimped. You can't rearrange photos, nor can you upload. I know the watch is important Tim, but at least ship software that is full featured.
