Q: Grey Lines Through Photos

Select a couple of these photos and export the Original version to the desktop by using the File ➙ Export ➙ Export Unmodified Originals for X Photos... menu option.

Once on the Desktop open them with Preview and see if you get the same corruption.  Another test is to drag of of the files into your browser's window and see if it appears the same or not.

Does it?

IT may be a problem with the graphics card or the memory on your Mac. As a test copy the original image files of a few photos to a thumbs drive and check them on a different computer.

I did do this.  It appears the same.  I will have to try the thumb drive test.  I opened them in Preview, Safari and Chrome just to see and it still came across.  I also did an export to the desktop and one other folder on the desktop just to mix it up but I still have the same result.

I really appreciate your help.  The strange thing is, it was only that week.  All of my other photos from my phone are uploading properly.  And one of the images in the middle of the "corrupted files" came out just fine. So out of that entire week, one photo was not corrupted.  It just doesn't make sense so I figured it may be a setting that was "bumped" but I'm on a 5S so I don't have the "Live Photo" setting.  I thought maybe it was a case of accidentally setting it to "Live Photo" so the upload was sketchy...but that's not my situation.

I started having a lot of photo problems when I upgraded to El Capitan.  And a lot of processing troubles as well.

hello,

Did you find any solution, same happened to me also.
