Using iMac Mid 2011 as second monitor for my iMac 2020
Hello all, I've been trying to find a way to use my iMac mid 2011 as second monitor for my newly bought iMac 2020. I bought the Thunderbolt 3 (USB-C) to Thunderbolt 2 Adaptor and the Thunderbolt Cable (All from Apple), and they DO NOT work!
I don't know what wrong with it? I even tried pressing command +F2, restarting all my computers, and they still don't work.
Anyone's having same problem? I need some help.
iMac 27″, macOS 10.15
