iMac (27-inch, Late 2013) as monitor for Mac Mini or Mac Studio
Can iMac (27-inch, Late 2013) be used as monitor for Mac Mini or Mac Studio? thank you
The Mac Studio is too new. The Mac Mini must have been produced in 2019 or earlier and be running Catalina
The large 2013 iMac must be running High Sierra or earlier.
