It is not normal, but there are people who hate iTunes and may even want to delete it from the Mac, something that in principle "cannot be done" but that with a couple of actions can be solved quickly.
Goodbye old friend
iTunes is in Lion write-protected by users, so we only have read permissions and we can't delete it… until we change it. To do this we go to the app, we secondary click and we give Obtain Information to have the screen that you see heading the entry.
Once we have that screen we have to click on the padlock to unlock Permissions options and later we only have to change the one from «Read only» to «Read and write» to be able to delete the app in a totally natural way, as we would with any other.
perfect is joke two days ago I was looking for something, thanks
but there is a problem it does not allow you to install an older versionaaaaaaaaaa
Dear, I have a problem with an audiobook purchased from audible that I can listen to on itunes from my iMac, but I can't hear the same audio on my macbook pro laptop, can you help me?
Well, it won't let me change privileges because it tells me I don't have the "necessary permission." What I do?
You have to find how to unlock the root user and enter with it and you do it, there are other ways but that is the simplest, search in goo how the user is activated, it is very simple.
