Hello! I am wondering how to delete Local Files off of a mac because I don't use iTunes anymore! Everyone is saying that you have to delete the file folder, but I don't know how to get to there. Any help would be appreciated!
The process provided in this Answer should clear the local files out of your app. I've copied it below for quick reference and hope it fixes your concern. Feel free to reply and let me know how it goes or if you need more help.
Have an awesome day! :)
