This only works for a different person's mac, and I believe they have to accept the connection. That's maybe fine for OP's purposes, but if I truly want to get back to *my* mac when I (and hopefully no one else) is there, still looking for a simple, free for occasional use, trustworthy solution. RIP actual back to my macThere are many people who do not know that the Apple Screen Sharing App is not limited to a local network.
Open the screen sharing app, choose "new connection" from the menu and then enter the AppleID of the person you want to connect to. (The other person needs to have "Screen Sharing" enabled and they will receive a prompt to accept or deny the connection.)
It took me 10 years to figure that out...![]()
