I recently purchased a Mac Book Pro and am trying to transfer as much stuff from my previous PC as possible. To do this, I am using an external hard drive that has all of it on it. I finally got around to attempting to transfer all of my photos, but encountered a problem. When I open up the external HD icon, I copied my photos folder from it into the Mac Finder Photos folder. I then went to access that folder, but I can't. The folder has a padlock on it and says that I not authorized to access it. Anyone know how to fix this. Please let me know, thanks.
