Wow, such a lot of hassle to do a screen capture ! I didn't even know that it was possible until I got my iPad, and with this, doing a screen capture is as simple as pushing two little buttons at one time. I am glad that I never needed to do it with my computer, because I would have had no idea how to do it, or that there was a special program designed for it.
TG, as advanced as Apple is, I would think that your Mac should have a fairly simple way to do a screen capture, as well ?
I would love to have a Mac laptop, because there are some things that a real computer can do that the iPad can't, and my old PC is as slow as molasses anymore.
My kids all have Apple and love them.
