One of my mates recently got me a mac book air but the whole thing is in Chinese! I've tried to restore it (commandR) and then it restarts and just goes Chinese every time. It eventually loads to the Mac OS sierra of some sort not sure which one! I'm unsure which one it is because it's in Chinese! Someone please help me! I've even tried to translate the Chinese writing myself to see if it looks the same as the symbols on the mac screen to whatever information I am looking at for preference! Pls help
