I might have to reinstall mac os x on my macbook but im worried about loosing my entire itunes library which is about 3000 songs. Currently on the second computer which is a pc has the same exact songs as the macbook. I was hoping that after reinstalling mac os x i would be able to plug my macbook to my computer and then transfer all the songs over or maybe do using my wifi. I hope this is possible if its not i might have to find some other way to do it or at the worst i will have to import all the cd's all over again which could take hours if not days lol. If anybody has any suggest please post thanks.
