Well, last day i was playing a videogame, but when i closed it, my screen turned darker than usual, i tried to get the bright to maximum but it didn’t changed anything, i tried to put down the volume and it worked, it worked everything but the screen is too dark, even tough that my mac work, but i don’t know if it’s a serious or uncommon problem
