Hi, I just purchased a new 2015 rMBP, my first Apple computer in over 30 years, and am still in the process of setting it up. I'm using the rMBP to host iTunes and am trying to copy my music library over to the new laptop. I went through the process of backing up and copying the iTunes library via an external drive and have copied the library to the mac and placed it in the /Music/iTunes/iTunes Media/ folder. Additionally, I confirmed in preferences that the "iTunes Media folder location" is the same; Music/iTunes/iTunes Media. However, my music isn't showing up in my iTunes library. Oddly, when I select a track to listen from the folder, and it open with iTunes and than appears in the iTunes library - but only that one track. Is there a way to have iTunes index all of the trades in the iTunes Media folder without me having to open each one? I've done some research, but can't find something that addresses this problem. Thank you for any advice.
