Thanks for the answer, so it means it safe to play high graphics games in Mac even it is not from apple App Store. the only thing that ruin the computer is overheating due to over used and not placing in ventelated table.
Just make sure your computer meets the system requirements for the games or other software so they run properly.
Also, just because an app is available in the Apple App Store, does not mean the app is good or problem free. There is a lot of junk apps in the App Store. You should always do your research before installing software no matter where the app comes from.
