I recently reinstalled iTunes and I noticed something peculiar. The "original" version of iTunes has a user in the permissions known as "wheel" that is set to "Read Only". I dragged this version of iTunes to the trash and installed a new copy, and when I look at the properties for iTunes it no longer says wheel, but rather just admin.
Here is a screenshot with the new version (left) and the old version (right):
What is the "wheel" user"? How is it set (I can't seem to set it in the GUI)? Why would the permissions be different now? It's not a problem, I'm just terribly curious.
8I know this is old, but "wheel" is a group, not a user. – Rich Homolka – 2012-11-15T15:35:45.707
