Issues using my 2013 27 inch iMac as an external Monitor with my 2020 27inch iMac.
Hi Everyone,
I just purchased the 2020 iMac and was hoping to use my 2013 iMac as an external monitor. Unfortunately after connecting the thunderbolt 3 to thunderbolt 2 adapter and pressing Command F2, nothing happens. I've tried while both Machines were running Catalina. I tried downgrading my OS on my 2013 iMac to Mojave, High sierra, and even mavericks. Does anyone has any advise?
Thanks,
Jamie
