Unable to upload, but also unable to download!
Hi - this is a weird one.
I have a 2012 MacBook Pro running High Sierra, and Photos 3.0. I know it's old but bear with me.
I am using iCloud Photos, which runs fine across all of my devices, apart from the MacBook.
On Photos on the MacBook I have an album "Unable to upload to iCloud" (which is fine - as I'm familiar with this from other computers) HOWEVER... when I try and either export those photos, or revert to original, or basically do anything with those specific photos... the computer seems to try and download them from iCloud (even though they're not uploaded!). It says "Downloading Items for Sharing". So, it basically results in Photos crashing / sitting there for hours trying to download a photo which isn't uploaded.
I have about 1500 photos in this album so I'd really like to solve the problem.
Any ideas please?
MacBook Pro 13″, macOS 10.13
