Target Display Mode
Is it possible to use target display mode to use my iMac (21.5”, late-2015, Catalina 10.15.6) as an external monitor but use my Macbook (13”, 2020, Catalina 10.15.6) as the main processing machine?
MacBook Pro 13″, macOS 10.15
no last imac that supported target display mode was 2014 one
