I could use my PC with my eyes closed but am finding the Mac a little difficult to transition into. IPhoto is giving me fits. When I pull up my photos (which I am still trying to adjust to the file system) I am looking to Edit but all I have are thumbnails at the bottom and nothing within the larger black screen. I have click and have tried everything and I can't get the picture into the center screen to edit. May seem like a logical answer here, but it seems as though something is way off. PLEASE help!
