- I have here a dozen Apple computers running on "MacOS Catalina 10.15.7";
- These Apple computers cannot be updated using the built-in system update application;
- I need to install XCode on them;
- The App Store offers only one version of XCode;
- The version of XCode offered by the App Store requires "MacOS 13".
Which ways do I have to I install an older version of XCode (ideally, Xcode 12.4) on MacOS Catalina 10.15.7?
