13" mid 2011, MacBook Air and have Mac OS High Sierra version 10.13.6.
I have an old 13" mid 2011 MacBook Air that uses MacOS High Sierra version 10.13.6. I need to download software updates but unfortunately, to do so I need to upgrade. Can you tell me how I can accomplish this?
Thank you in advance,
