My mac was sitting on a couch and my dad accidentally spilled some beer on the mac. The mac was closed and already shut down. It spilled towards the back where the hinge is mainly. I tried to turn it on about a day later but it didnt work. When I try to charge it, the charging cable doesn't light up. I thought there was a problem with the cable but after borrowing my friends cable it still wasn't working. What's wrong with my mac? Who should I see to get it repaired? And how much will it cost?
