My sister has a MacBookPro that she just upgraded to the latest OS of Yosemite 10. In trying to find the location of her picture files on her Hd; I noticed that she didn't have her sidebar in Finder activated. I set it to show and ticked of all the selections in the dialogue box for "Show these items in the sidebar". These selections still do not show. Wondering what I have to do to get them to show as they should?
