Hi there! I can't install macOS Catalina...it s says "This copy of the macOS Catalina installer application is too old to be opened on this version of macOS" ( macOS Big Sur 11.1-iMac (Retina 5K, 27-inch, Late 2014))
iMac Line (2012 and Later)
That's because Big Sur is newer. Why are you trying to install Catalina?
