MacBook Air (mid-2013) upgrade to Mojave
When I click on the Mojave 10.14 link given in the support page "How to get older versions of mac os," the app store opens to the Mojave page, but no installer downloads, and if I click on "Open," I get a message that the installer is damaged. I don't want to upgrade to Catalina or later, due to 32-bit concerns.
