iTunes won't let me change song information and hangs up...
Using an 2010 iMac and iTunes 11.x I tried to change some song information as I did it for several years and iTunes versions.
Now it seems to be an installation error and the program hangs up if I try to open the information pop up.
The music plays on but nothing else can be done as to quit iTunes (hard quit).
A reinstallation doesn't had any impact, but I was not able to deinstall iTunes first (error message: ...this program is part of OS X and cannot be deleted...)
I also checked the hard disk and the right management, everything seems to be fine.
Has anybody an idea how to get iTunes de- and reinstalled completely?
I did not find an guide for that.
Thanks in advance for your help.
iTunes -OTHER, OS X Mavericks (10.9.1), 27" iMac i7 2010
