Right, Hey guys, recently my OSX just went mental. I can't really describe it, but i can show it. Pictures are below. Basically, All the OSX icons have just disappeared. On the dock the 'Application', 'Documents', and 'Downloads' folder icon's have just turn to question marks; ?. And in Finder, there are literally just no icons, only on my apps, no folders. Lastly, i can't open up image files either. Preview isn't realising that the .jpg files are image files and when i try to open with Preview, it just doesn't open; however, all image files open up with Xcode! lol, i really don't know why, but they do show up as shown in the pictures below. Any ideas?!? REALLY SCARED!
