Hello all, I am trying to clean up and arrange my iTunes music library. In iTunes when I right click on a song and click "get info", then change some info, it doesn't stick. It goes right back to what I already had in there before. I then realized that this is because every file inside my iTunes music folder is set for "read only" and not "read & write". So after I change it to "read & write" all changes I make in iTunes will take. However, I have a lot of music and therefore a lot of files inside my iTunes music folder. Going into each and every folder to change its permission to "read & write" would be tedious and time consuming, not to mention extremely annoying. Is there any way I can change that permission for every file on my iMac via one or two clicks? Like is there a system wide option for this? Thanks!
