Back up. Punt again.
Hahahahahaaa! I guess it's good to be so underemployed!
I have four computers and 2 iPads on my "Network", so I guess I qualify as an Administrator. They access each other wirelessly, and have done so for eons before the Windoze folk caught onto that design thing. Oops, it was the PC manufacturers, since MS only makes software.
I run Parallels, which allows me to use Windoze programs on my Macs. I have it so I can run Microsoft Flight Simulator. It's the only program not available for Mac these days.
I turn them on and leave them on! They sleep as needed. Me, too!
