ok ive looked around and tried several things, but for the life of me, and this mac pro (2008 version) once i upgraded to el capiton o crap, it wont let me log into my itunes account nor will it let me log into my app store account, i put each password in and let them sit and the little wheel spin for like an hour or longer and nothing!!
what can i do? ive tried restarting, re installing, and a few other things to no avail
