Like htop, there are nvtop and mactop... They're used to check how hard your computer is working.. To see if you need to push it harder or whip it here... You have to check the status of the slave...
Usually, you can tell by the fan noise... When you pull the full throttle to take off ㅜㅜ

You can easily install it with 'brew install mactop'.
If homebrew is not installed, you can easily install it after searching.
