How to Upgrade macOS when no Mac OS is appearing on App Store search, and safari application won’t run?
I'm currently on El Capitan 10.11.6 but I need to update my MacOS. The issue I am having is I can’t seem to upgrade to Mac OS Catalina - which is required to run my version of safari. I have searched on the App Store for Catalina and other mac OS’s but none appear. As I also cannot access safari to download Catalina, I’m at a loss of how I can upgrade my Mac OS so I can run safari and other applications.
Any help would be appreciated thanks.
