Okay so I just got a Mac Air 11 and am trying to hook up my iPad 2 with my itunes library which is on an external hard drive. I also have another ipad 2 hooked up to my PC with the itunes library on the external drive. It works fine which is why I would like to do the same thing with the Mac Air and 2nd ipad using the same library. I can see the itunes library on the external drive when it i hooked up to the Mac Air but can't seem to get the MacAir itunes to connect/recognize it or else I don't know how to get everything to be recognized while leaving the files on the external drive. I am using the same name on both ipads thinking that would take care of the problem. Guess I am missing a step or two to complete the process. Because my itunes library is about 675 GBs, I don't want nor can I transfer the library to my 128GB MacAir. How can I get this straighten out? Thanks.
