Is Minecraft Still Harming a Mac?

A year ago I downloaded the Minecraft demo onto my Mac. It's from 2018 and has MacOsBigSur with 32GB Ram so that's no problem. However, after a while, my PC became totally slow. And that was also the case with a friend who got the full version. I then had to reset my Mac and saved important things on a hard drive because deleting it didn't work.

I wonder if this is still the case since the Big Sur update or if something can be done against it or if something has to be observed during the installation so that it doesn't happen.

-Thanks for answers.

This is certainly not due to Minecraft

What can you do about it or what can you do about it?

I don't know, I don't know enough to know.
