Heaven’s man, what’s the panic? Yeah it’s pretty easy to learn a few things and do a lot more out of the box.
Panic? Yes, there is panic.
I’m a legend in my own mind. I have important work in my time off here to educate the unwashed masses in the proletariet on other sites.
Do you have a MAC?
MAC? That would be MAC address you are asking about?
Oh - Mac (as in the Macintosh)....got ya!
What are you trying to figure out?
Which model?
Plug it in?
Connect cables?
Mouse connected?
Press power button?
Does it boot up?
Have you used a computer of any type before now? The basics of computer use are not really much different. If you can use a Windows-based PC, then a Macintosh should be much like that, but more intuitive (logical) and simple.
There should also be a Getting Started page that came with the computer. Also, every Macintosh I have ever purchased has come with a set-up guide that also is a demo of how to get started. In fact, I believe it auto-runs the first time you boot the computer (but it has been a couple of years, so I don’t quite remember). But is called something like Setup Assistant. There should also be “Guided Tour” which shows all the basics of operation.
Anything more than that and you will have to be more specific with us so we can help you.
