This question already has an answer here:

I have a MacBook Air running Mac OS X Lion 10.7.5. I wish to upgrade it to macOS Sierra, but it requires at-least OS X Mountain Lion 10.8 which is not available anymore in the App Store.

Is there any other way to update the OS?

I figured out I can still download El Capitan so should solve the problem.


If you aren't specifically looking to run macOS Sierra, Apple recommends upgrading to macOS High Sierra.

You can find the instructions to download and install macOS Sierra here:
