Unable to download apps due to not being supported.
I am currently using an iMac (21.5 inch, Mid 2011) Which is unable to support the new mac OS Catalina system. I am however unable to download any apps as I get the error message 'can't be installed on ''Macintosh HS'' because mac OS version 10.14 or later is required. ' Does this now mean I will be unable to install any further apps? Any help would be gratefully received.
