icloud mac photos not syncing
I have iCloud turned on for my iPhone and Mac. Half way through the initial sync of 50,000 items it stopped uploading. Now i have 25k on my iPhone and in the cloud. My mac has 50,000 (although none of the recent ones too on my iPhone) which is stuck on 'uploading' (and has been for several weeks now). I have space on my hard drive (although only 50GB) so unsure why it's stopped uploading and downloading. Does anybody have a solution please?
