Running Hi Sierra 10.13.6 ; Can I upgrade safely to Catalina (10.15) or newer.? It appears every day now Google Meet, Formstack Sign or som type of correspondence is not being supported by my OS . Any Suggestions? Other than empty the piggy and go buy new?

High Sierra is the last possible. See the following from Identify your iMac model - Apple Support
Identify your iMac model - Apple Support
iMac (21.5-inch, Mid 2011)
Model Identifier: iMac12,1
Part Number: MC309xx/A, MC812xx/A
Newest compatible operating system: macOS High Sierra
Chrome still supports their latest browser version on High Sierra so that may help. See: https://support.google.com/chrome/a/answer/7100626?hl=en
sorry, no. high Sierra is as far as that Mac can go. maybe try Firefox.
IMac 21.5 inch Mid 2011 Is it relevant?
