Macbook iPhoto wont Sync iPhone 5s photos older than "recent"
I have a macbook pro running on Mac OS Sierra version 10.12. i am currently running into problems trying to sync photos from my iPhone 5s (running with 10.3.3 update)... and i have over 1800 photos that i can't get off my phone which keeps dying because it is TOO FULL! i am trying to sync them to my mac so that i can free up some space on my phone to have more than just the bare bone essential apps. I have had to delete numerous important ones too just to make room. As soon as i have my iPhone connected everything syncs. iPhoto does have the option to open all recent photos from this iPhone & the option to press "import selected" or "import all" are there on the top of the screen, but i can't press them. they arent able to be selected. it id sync my most recent. 3 pictures. now i have 1797 to go!
Has anyone else encountered this!!! This is quite frustrating. Please Help!!... I tried a couple of the other suggestions with people who encountered similar issues & tried to sign out & sign back in on my devices of my iTunes account from my system preferences. That did not work for this issue.
Thanks in advance!
