Ok I understand that but I more of wanted to know if I could upgrade it further because there are many downloads on the App Store that require 10.14 or later to get them and I don’t know how to upgrade mine. I have a MacBook Air mid 2011
Is it possible to further upgrade my MacBook Air mid 2011 from High Sierra 10.13.6 considering many apps on the App Store require a later version and also because I can’t find my safari and when I tried to re install it it said that there was no application set to open the URL http://www.apple.com/safari/. And the solution it said is that I need to re install my mac OS and I want to use the opportunity to upgrade
MacBook Air 11″, macOS 10.13
