I am trying to change my desktop image. But, when I go to system preferences and click on "desktop images and screen saver", the pinwheel will not stop spinning. I cn only force quit system preferences.
I have shut down the computer and restarted a number of times, but the same thing happens.
Anyone have a suggestion?
I realized that the cause was the iPhoto library folder because I removed the folder (you can only rename it for a test) and the system preferences now is ok.
I don't use iPhoto but I made some test so I think probably there were some corrupted file in the iPhoto's library folder.
I hope this can help you.
