Aperture 3.6 not showing images, just a black screen
Hallo
I recently installed Aperture 3.6 in an old MacPro 2.1 with El Capitan, and I transferred the library (very big, around 250 000, mostly referenced files, so I reconnected them).
Problem is, I see all the previews but when I click on any image it does not show, just a black screen. The metadata are there, the curves change if I change image, but I just don't see it.
I tried importing new pictures, same behavior, so it's not the referenced images. I found some pictures within the aperture library, even those don't show.
There is no error whatsoever, or any other strange behavior other than this up to now.
Thanks in advance for any ideas on how to deal with this
Mac Pro, OS X 10.11
