Issues with editing pictures using "photos"
Looking for an explanation/solution to me problem editing pictures using "Photos" I'm using a Late 2011 13' MacBook Pro. I am able to crop or rotate the image, but as soon as I try to adjust the colours or lighting on my RAW images taken from my DSLR I get the below image. I have tried repairing the library, and have also opened a new library and imported 1 picture into that library and the same problem exists when I try to edit. I will also occasionally get the missing thumbnail or blacked out picture in place of the blue screen below, but after restarting the picture can be viewed again with no issues (but not edited)
All photos are stored on internal Mac hard drive. Running macOS Sierra 10.12.6 with no updates showing available for my MacBook Pro.
Thanks for any help or input.
