I've been having troubles with iTunes : it was working yesterday morning, and after I restarted my computer it will no longer run, it just gives me an empty message box
and if I leave it for a moment an error appears:
The problem occurred when I was on a old version of OSX, so I updated to Sierra and to the newest version of iTunes as well, didn't change a thing. What I have tried :
Install Sierra with iTunes 12.5.4
Try to remove iTunes, I just have a message : iTunes can't be modified or deleted since Mac OS requires it
Try and download iTunes from the Apple website : the available one was 12.4.3, so when I try to install it tells me a newer version is already installed and stops.
Any ideas ?
Thanks in advance.
