How do I completely reset iTunes?
I've been having a lot of issues with my iTunes account syncing with my phone because somehow I have a ton of music in my iTunes that my husband downloaded or saved with his old Apple ID (two different old Apple IDs actually) and because of that, I can't sync properly. I've been trying to figure it out but I think the only way to handle it might be to just start from scratch. We have most of our music saved to an external hard drive so if I can somehow just clean out iTunes on my Mac and on my iPhone, I can just restart by downloading the music I want from our external hard drive.
Does anyone know how to fix this issue? I have an iPhone 6s and a Mac running Yosemite.
Thanks for any input!
