It's my first time to own a Mac, Macbook Air 2018. Im so used in using Windows laptop that I know its limitations. I have few questions about my Mac: A. Is it ok to play my Android games on my MBA 2018, using Bluestacks Android emulator, without worrying about the heat destroying the components inside? I had to search google, if this machine has a fan. Im shocked, it does, cause I don't hear it much. B. How do you remove the oil on the keyboard? Alcohol + Water, is it safe?
