Can I play games online on the Macbook Air without having to worry about my laptop? Namely, I do not want anything to break because the laptop was bought relatively new. Games I mean are, so to speak, "children's games" on games monkeys and slochen websites. (Have an ad blocker and Adobe Flash Player)
You can play what you want the operating system is very closed will happen nothing but MacBooks are not made for the game as the performance will be moderate
Browser games require as good as little power except for a good internet connection. As long as these sites do not show so many ads and you have an adblocker, next to nothing bad will happen. In addition, the Mac is synonymous not overwhelmed or so. So everything is fine.
This is about browser games and not these PC games that you have to download. So the performance will be good. Prerequisite is a sufficient Internet line.
