My iMac desktop is about 7 years old. Currently it runs on OS X Yosemite, version 10.10.5. I want to know if it is compatible with the newest operating system (Catalina) and if it is recommended to install Catalina? Thank you.
iMac 21.5″, OS X 10.10
Catalina can be installed on iMacs 2012 or later. See compatibility information in: How to upgrade to macOS Catalina - Apple Support

Before installing Catalina, update all apps and look for any that are still 32-bit.
32-bit app compatibility with macOS High Sierra 10.13.4 and later - Apple Support
