This doesn't only apply to iMacs but in my username link on the sidebar of the finder the applications folder had only about 3 applications in it and the rest were corrupt or damaged as it says. Is this a problem what could I do to get them back in? All of my applications are still in the Macintosh HD folder though. And I know I could just make an alias of the applications folder in Macintosh HD but it shows a link on the folder and it looks weird so what could I do please help?
