How to Transfer iTunes to a Laptop (5 Steps)

Plug your iPod into your old computer and ensure that all of the music from iTunes on that computer has been successfully transferred to your iPod. If you plug in your iPod regularly, this synchronization process should only take a few moments. When the synchronization is complete, unplug your iPod from this computer.
Install iTunes on your new laptop if you do not already have it. Do this by going to the Apple website (see Resources), clicking on the 'Download iTunes' link and following the prompts. Open iTunes once the installation is complete.
Plug your iPod with all the songs you want to transfer into the laptop onto which you want to transfer them. This will prompt iTunes to open a window with three options: 'Cancel,' 'Erase and Sync' (which erases all the songs on your iPod that are not on your laptop and then synchronizes your iPod to the laptop) and 'Transfer Purchases.' This last option transfers all the authorized iTunes purchases on your iPod to the new computer.
Click on 'Transfer Purchases.' This will open a new window asking you whether you want to 'authorize this computer for items purchased from the iTunes store.' Click 'Authorize.' Next, iTunes will prompt you to log in with your Apple ID and password. Click 'Authorize' again when you have done this.
Click the 'OK' button on the window that appears telling you how many computers you have authorized with this account (out of a limit of five). This will prompt the transfer from your iPod to your new laptop to begin.
