Can't use iMac as monitor for new MacBook?
I have no problem using my iMac mid 2011 as monitor for my old Macbook Pro (2017, macOS Catalina 10.15.7) using a Thunderbolt 3 - thunderbolt 2 adapter.
However, it doesn't work if i plug my new Macbook Pro (2020, macOS Big Sur 11.0.1) into the same set up.
The ports on the Macbooks are identical and using the same exact set up.
Could it be bc of the 2020 mac is running a later software?
