Big sur update

Hello gio8886,

We'd love to assist you with your Mac performance. Let's complete the steps listed here: See how apps affect Mac performance, battery runtime, temperature and fan activity to resolve the issue.

Also, let's see if the issue occurs in safe mode. If you are not familiar with the safe mode steps, you can follow the steps here: safe mode to get it done. Once in safe mode, you'd want to use the Mac as you normally would to see if the issue occurs again. You can tell when the Mac is in safe mode because on the desktop it will show the words Safe Boot in the top right-hand corner of the screen.

Take care!
