Disconnected iPhone from iCloud to connect mac. Photos wont upload
History of my photos.
My iPhone holds most of my photos and due to constantly printing I need the higher quality so I do not enable the feature to keep the smaller versions on my phone. As my phone was full, i turned iCloud photos off on my mobile then deleted all the photos in my iCloud account so I can now sync my mac to iCloud as my mac is the place I store all my life's worth of photos. I cant for the life of me get the photos app to upload the photos to iCloud. I have checked all settings, restarted etc. Any further advise.
iMac 27″, macOS 10.15
