your playlist should be saved automatically in an itunes folder on your C drive, if not you can just go to the top and go file and save another 1 now if that file is mac compatible then its very easy just transfer your music files onto your mac into say a folder named Gandy's music, then add the folder to the itunes on your mac and then import the playlist and it should rename all your files to what you already had them at i went from windows to windows and it worked perfectly, about 10 minutes including import time fingers crossed it works on mac if not google it but when i was doing it the tutorials are overly long and half the steps arent needed... hope this helps
