Updated to Mavericks, aperture 2.1.4 crashing and thumbnails are black
HELP! Just updated to mavericks and now my aperture 2.1.4 is playing up. It is either crashing all the time or sometimes when I am trying to edit I click on the thumbnail and a black picture comes up instead. Can see the image in the browser but in the viewer it is black! When I try to export the image as a JPEG it is a black JPEG. Should I just update to the latest Aperture? Will this solve the problem or are there problems with my library???
OS X Mavericks (10.9)
