Consolidating songs on itunes into one album
It won't store items like PDFs or full uploads of WAV files you may have recorded, however.
You don’t have to download an extra app, because Migration Assistant is included in Mac OS natively.
Don’t feel like messing around with the Migration Assistant?
You could always hook up an external hard drive and transfer your music files manually from one computer to another.
After decades of digital music, it's not unlikely if you've amassed quite the collection of music on your computer's hard drive.
If your i Tunes library is taking up too much space, you can move it off of your local drive and onto an external hard drive without breaking your music collection.
When Migration Assistant asks how you want to transfer information on your new Mac, make sure you choose the option that says Now head over to your old Mac and open Migration Assistant there as well with the same process. Migration Assistant should next ask if you want to transfer information from a Mac, Time Machine backup, or a specific startup disk.
