How can I update the OS for my iMac 27 inch (late 2013) from High Sierra (10.13.6) to Catalina (10.15)?
I have looked in the APP store and system preferences for an update and cannot find anything to help me switch to Catalina.
iMac 27″, macOS 10.13
Welcome to Apple Support Communities.
Backup your files, download macOS Catalina from Safari: How to get old versions of macOS - Apple Support, then follow the prompts to run the macOS Installer.
