MacBook Air 10.9.5 to 10.11 or never
Hello,
I have a MacBook Air 11-inch 2014 with OS X 10.9.5 installed, and
unfortunately, due to security policies, practically nothing works. I
can't install applications from the App Store or browse the internet.
In the updates, I don't see anything. Is there any way to do it manually?
I've tried various solutions from the internet, but none of them work.
Please help me.
