Hi, I’m runnng Photos on my iMac with El Capitain, and have come across an issue. Quite often when I open Photos it tells me that it needs to repair the library, which I accept. After some minutes it then starts up and works as intended – however some of the photos from the Photostream might not be in the right order. Further it seesm to mess up some files as it then need to transfer all pictures again to the iCloud-Photolibrary. I have the original placed at this Mac and have Photostream activated. – I have around 9000 pictures. What can I do to get rid of this returning issue?
