I did a clean install of HS and I have been having trouble syncing to iCloud since then. Not sure if this is a common bug, but whenever I edit a picture or contact on my Mac, it does not go to iCloud nor does it sync with my phone/iDevices. It is definitely my Mac cause the other devices do sync to iCloud. I did try resetting the NVRAM (etc), deleting all AddressBook/AddressBookSync folders (which only fixed it one time), and signing in and out of iCloud (as well as checking / unchecking just contacts). This issue also happens on Safe Boot, so it appears to be HS related. And yes, both devices have iCloud as the default account. Anybody know a fix for this or experiencing similar issues?
