Hello, I would like to know if it’s possible to use a PC laptop as the second monitor of my old 2012 MacBook pro? Thank you very much for your advice.
You could install a VNC Server on your Mac and start VNC viewer on PC
This way you mirror the MAC on the PC and could act on PC.
But you need a Network
The Mac already has a VNC server - just turn on Screen Sharing
Thanks for your helps, I’ll try them and tell you.
