I need help with launching fortnite on my macbook air

I have a Macbook Air bought in 2010 and I am trying to play fortnite. I have the High Sierra update. Whenever I launch the game it says I don’t have a metal compatible graphics card. Can anyone give me a walkthrough on how to fix this because I don’t know much about computers.

You most likely won’t find Fortnite help here this sanwserhub is primerly for UE4, in future either contact forenite support or post on forenite forum https://www.epicgames.com/fortnite/forums

But “metal compatible graphics card” sounds like you trying to run on Intel GPU which UE4 have trouble running in, do your Macbook Air don’t have better GPU?
