Screen sharing on a mac without user intervention?
 

So I am trying to see my 89-year old mother's Mac screen. I can initiate screen sharing via Messages, but she just cannot negotiate the dialog box to accept the connection.

What is the easiest way for me to take over her computer without her having to select something? I think I turned on screen sharing and I am an admin on her computer, so I think I can connect via VNC or something, but then I'd have to know her IP address, which can change. A long time ago, I used to use DDNS and was able to do this sort of thing, but that all broke for several years when her ISP changed her modem, and we can only do basic screen sharing lately, so I am starting over from scratch in a way.

Teamviewer should work. But for that you'd need access to her computer to set it up. That and a Teamviewer account. You install the client, add it to your account (make sure you have 2FA enabled for security purposes) and then voila.You can take control whenever you'd need to.

Anydesk should work as well.

you should be able run ddclient on her mac, which takes care of the DDNS stuff. I think it's just a perl script that you can set up to run as a service. I'm pretty sure I used on my raspberry pi, and maybe on my mac mini at one point.

dyndns has their own list of update clients, I think I used to run this on my mac mini when I needed it: https://help.dyn.com/update-clients/

+1 for Teamviewer. But, when working with my near 80 year old, he has trouble double clicking on HIS Teamviewer icon on his desktop and relaying to me the particular details (computer ID and password) that I need to enter on my computer to login to his computer.

If you link the client to your account, you don't need this. Just make sure your account is secure.
