Can I use my older mac as a dual monitor?
I just bought a 2021 iM MacBook Pro with all the bells and whistles so I can teach online without a hitch. Prior to this new computer I used a 2014 MacBook Air and used an HDMI cable to use a tv as a second monitor. I don't need such a large device in my room, can I use my old mac as the dual monitor and get rid of tv?
If so, how? What cables (if any) do I need? Any programs, apps or extensions that will work?
I love having the extra monitor to keep an eye on kiddos working online while I teach using the new mac.
Thank you in advance.
