A guy at work as a mid 2011 iMac. He is looking to get a new Mac as he cannot upgrade any further. I suggested a Mac Mini because of the price point. He wants to use his old iMac as a monitor and I know this can be done starting with mid 2011 (which his is). Can I run HDMI from the Mac Mini M1 to an adapter that turns it into the display port/thunderbolt port to connect to the iMac to use it as a screen? I am assuming it will work but not 100% positive with the HDMI converting to thunderbolt.
