If you can't manage........
I beg to differ. I've worked in quite a few places that use Windows and Macs. It just takes a bit of work and learning to integrate the two. If you can't manage that then you really, really don't belong in IT.
A school I personally know of ran Mac Servers, iMac, MacBook, iPads and iPods. The Principal wanted to have the iPods networked in so they could use Graphic Calculator software and upgrade it instead of paying a couple of hundred dollars for a dedicated hardware device. Senior Apple people spent $100,000 in time trying to get the iPods online before throwing in the towel. Mac hardware not wanting to work with other Mac hardware…..PRICELESS. Based on your own words I guess the Apple engineers just really, really don’t belong in IT.
It isn’t the only time that Apple gear didn’t want to play nice and the Apple engineers again threw the hands in the air in defeat.
