macOS Catalina 10.15.7

there is no .iso ... it downloads as a .app and ends up in your Applications folder, +/- 8GB (full installer)

or from the Terminal.app

sudo softwareupdate --fetch-full-installer --full-installer-version 10.15.7

The latest macOS (iOS is for iPhones and iPads) you can install on the 2012 MBP is 10.15 Catalina.
