Manually transfer your iTunes library to a new Mac
Library transfer can be done in several, and perhaps obvious ways, using a USB thumb drive or hard drive, or via networking and file sharing. Depending on the size of your library and the connection speed of your Wi-Fi network, you might consider using a direct Ethernet connection or other option to swiftly transfer your library between computers.When your systems are connected, you can transfer the iTunes folder from the Macintosh HD > Users > username > Music directory on the old system to the same directory on the new system, replacing the current iTunes folder (if present), and then simply launching iTunes. Since this is the default location for the iTunes library, the program should simply adopt the new library and its media; however, if it does not, or if you have placed the copied library in a different location, then you will not see your music in iTunes and will have to re-associate your library with the program.Ensure the iTunes Media folder is the appropriate one, especially if your library is being stored in a non-standard location such as on an external hard drive.Screenshot by Topher Kessler/CNETTo do this, quit iTunes and re-launch it while holding Option. When you do this, you will see a library selector window pop up which offers an option to create a new library or to choose an existing library. Select the option to Choose Library, and then navigate to the iTunes library folder you previously copied, and select the "iTunes Library.itl" file within.Now when iTunes launches, you should see your music and playlists appear. But now you will need to ensure your media folder is properly set so iTunes can find the files for your songs. To do this, go to the Advanced section of the iTunes preferences, and click the "Change..." button. Now navigate to the iTunes folder you copied to the system, and choose the iTunes Media folder within it.With these settings checked, iTunes should now properly associate your library and media files, and you should be up and running. The only additional step you may need to complete is to sign in with your Apple ID so any DRM-protected files can be played.Questions? Comments? Have a fix?
