I just recently purchased a 24" imac and I am having trouble transfering my itunes library files on my new imac? When its connected to the PC I can view and see the files on the external hard drive but when I connect the external hard drive to the imac and I try to add those files to the itunes library they are not visible to add? Now I have been trying to fix this issue watching youtube videos and reading all the proper steps for the past week and still nothing has helped..... I'm new to this so if you guys could please help me out I would really appreciate it. Thanks for reading my post.
