Can I sync itunes between my two mac laptops?
Sign in to both computers with iTunes home sharing - then you can import files back and forth as needed. There is a filter to show songs not on the local library and the copying is drag and drop.

Much faster if you really want to copy files than iTunes Match which also would sync things, but take far longer to upload and download the files.
