Now I have installed RT 5.4. But I can’t process an image. If in the Editor I click the little sprocket at bottom left, nothing happens. Now I can’t go back to 5.3, which worked earlier, it’s the same there. Re-starting the Mac (10.11.6) doesn’t help. What can I do?
The image in question is a file from a Fuji E900.
Thank you for your help.
