So I checked the threads on here and tried multiple ways and cant figure this out. I have a MBP, itunes 10.1.1, and a western digital passport essential. I loaded pictures and my old itunes library off a HP pavilion desktop. On my Mac, when I try and open my external hard drive off the desktop and click my itunes library file I stored from my old HP it simply wont open. I right click it and click open with itunes and the file icon fades off my screen very quickly like its trying to import it but wont. I have tried dragging it and holding option when opening itunes, which actually does display the playlist but only with explanation points because the files cannot be found. I just want to be able to plug my external in and listen to my playlist I have stored on the western digital, on my mac book without erasing my current itunes playlist on my MBP. How should I go about this? What am I missing?
