Hello, I search for an application compatible with OSX 10.6.8 to transfer my music to an iPad 4? I can't do that with iTunes because OSX 10.6.8 is too old.
You can use SharePod or iExplorer to transfer the music to your iPad. In some cases, you don't even need iTunes to be installed, but since you're on Mac, you might have to let it there since it can't be removed because it's a marked as a system application.
