My mid2007 iMac w/ OS X El Capitan (version 10.11.6, 2GHz Intel Core 2 duo processor, 4GB 667 MHz DDR2 SDRAM); how can I upgrade to Catalina? do I need an external memory card to provide sufficient SDRAM?
El Capitan is the last operating system that your 2007 iMac can install. Use any iMac manufactured in 2012 or later to install Catalina. See How to upgrade to macOS Catalina.
