You don’t have to live near someone. Most of the remote meetings tools today allow a person to remotely work on your Mac for you while you watch and talk with the person.
Zoom is just one of these.
Yes! I had this done when I bought a new Mac Mini M1. It was awesome but it was a low end Mac and I decided I wanted to wait for a higher end version with more RAM. So after playing with it for a few days I wanted to do a clean installation of the OS and landed in a world of trouble. Now I’ve been on Macs since forever, late 80’s, and I can do a clean install in my dreams. But this one wouldn’t work, no matter all the tricks I pulled (turned out to be a bug which they fixed in a quick update). So I called them up and they were stumped too. The first guy couldn’t solve it, but the second said: I’ve been in computers for 20 years. This is a software bug and no software bug is going to beat me. He had to jump through a lot of hoops but he did solve the problem.
Anyway, as the Mac Mini was stuck at first and inaccessible, he first looked at the screen via my iPhone, that I had to hold up to the screen. Later, as we had control back over the Mac, we switched to direct remote control. He didn’t do anything himself, although he could have. Instead he pointed to where I needed to go. It was a weird sensation to suddenly not be alone on my computer! And all the while we were on the phone, talking. It worked miraculously well.
