Most of my mac users were fine, the people i had a problem with didn't matter what OS they used, it was the ones that complain a thing isn't working, you ask for confirmation that the thing is plugged in, they say yes it is plugged in, then you physically move to the workstation to find that it is not plugged in. If you have a legit problem, even if you caused it we're still cool. If you waste my time by lieing to me we are no longer cool.
