My browser is no longer supported on MacBook Pro macOS X El Capitan
Recently a lot of the pages I have tried browsing say that my browser is no longer supported. When I looked under the about this computer tab it says the version I am using is OS X El Capitan version 10.11.6 When I try and hit software updates I don't see any as being listed. What can I do to be able to visit simple pages I have always been able to access in the past?
