I have a MacBook Air 2011 currently on OS X 10.7.5.
I cannot access the App Store or download macOS High Sierra.
Can Apple provide a legal installer or guidance to upgrade my Mac safely?

First question. Why can't you ‘access’ the App Store? That’s where you download full installers of macOS. Don't even think about downloading it from anywhere other than Apple. You will regret it.

I might guess export controls or trade sanctions or denied persons are involved here, and we can’t help with any of that.
How can I legally upgrade my MacBook Air from macOS X 10.7.5 to macOS High Sierra?
