qwertyqwerty I have been using Mac OS since 1994... Worked tech support in private Apple Authorized store for 11 years (pre-Apple retail), have consulted for private companies utilizing OSX and have often interfaced and done work for Apple itself. I do not work for the silly Apple Retail, I am very sorry if this is a strict need for you. I'm a little past a "mall job."
Reach out if you need.
