Photos library not importing from time machine backup - 'Nothing to import' message
My iMac was having kernel panics and kept restarting, to cut a long story short a guy at the genius bar wiped my mac and installed El Capitan on my iMac (I was originally running Yosemite). I'm not fully restoring from backup to avoid any further kernel panics due to software, so I am only restoring iTunes and Photos manually by dragging and dropping. I've successfully imported my iTunes library, but the same cannot be said for Photos.
I located the photos library by going through to user>pictures on my time machine backup. However, when I go to import the file named Photos Library (Original), I get the message 'nothing to import'. If anyone could tell me what this means I would be very grateful!
Thanks
Jack
