I have a Macbook Pro, Retina mid 2012, version 10.11.3 and every time I try to shut down or quit Photos it says "Are you sure you want to Force Quit? You will lose any unsaved changes." Does this mean I will lose any photos I have on the app?
My computer's software needs to be updated, but the iPhotos appears to be stuck, and is apparently trying to "repair the library"...it's been like this for a few days. Is it safe to Force Quit out of the app? Will I lose any pictures I have on it?
