Mac Mini Late 2015 Yosemite 10.10.5 The last couple of days, everything has gone a bit t*ts up - I can no longer open many of the core apple applications, iPhoto, Safari ect. The app will bounce in the dock but then disappear. In the case of Safari, it'll open up a page but then dissapear within a few seconds. My disk is apparently full, but deleting things seems to have no effect - I cannot open iPhoto to delete any of my pictures. When I do try and move stuff to trash, instead of simply moving it'll give me a box telling me the file will be deleted immediately, which has never happened before. The problem doen't fix with restart. Please help.
