How do I restore wheel user?
I thought I had a virus issue so I started looking around at various settings and permissions. I noticed "wheel" as a user under sharing & Permissions. Unfortunately I deleted it prior to hitting Google to understand that it was supposed to be there. Thus far my computer is running ok and boots back up ok. 2 Questions....First, do I really need to add this back and if so why? Second, if I need to add it back how do I do that. I ran disk utility to fix permissions. It did several fixes, but did not restore wheel. How do I fix? I am on Yosemite.
