iMac (21.5-inch, Mid 2011) Can I updated from MacOS El Capitan to MacOS 10.15 or higher?
Can I update from El Capitan 10.11 to MacOS 10.15 or higher (I think it is Catalina) I check for updates and it says none available. I try to update via download and it says not compatible.
iMac 21.5″, OS X 10.11
