Hello,
2 months ago my trackpad started to not working well, i thought it was a dust under it but it wasn’t. Now i can’t even click it down and left part of my keyboard light’s are not working. I would like to take it to Genius Bar in London but since 2 weeks there’s no free places. I can go without an appointment? They will repair my MacBook Air without additional costs? It’s still under 1 year warranty
