Late 2013 iMac (iMac14,2), Catalina 10.15.8, Samsung 870 Evo SSD. OpenCore 2.4.1 installed correctly to internal EFI, external My Passport EFI, and a bootable USB installer with Ventura. NVRAM reset done. Boot picker never appears regardless of method. Option key at every possible timing does nothing. Machine boots straight to Catalina every time. What am I missing?
