I have my home Macbook pro's itunes library on a server. The library is on the server and the MBP just references that for its itunes. Everything works fine with it. I have a spare 250GB portable HD that I wanted to clone the itunes library to and bring it to work. On my work computer I will just set up itunes to reference the portable HD. Will this work or will it cause any problems between the two computers. I know they wont sync automatically or anything like that. Im not worried about that. I can just update my work one every so often. Has anyone else done this?
