We always want to know things that most people don’t. If you know something that only a few people do, you feel great about yourself. Here are eight fun commands that most people aren’t aware of.
Yes, your Mac can talk to you. Whatever you say, it will repeat it.
say “I am Groot” say “I am great at impressing people”
The say command will dictate whatever sentence you enter between the double quotes in the default system voice.
You can also change the voice by going to System Preferences → Accessibility, → Speech → System Voice pop-up menu, and then choosing a voice.
It’s a cool terminal command to prank others with.
If you’re not performing any interaction with your Mac, then it will enter into sleep mode to save energy. But in some cases, like when taking notes or reading a long article, you may forget to interact with your Mac and then have to enter your password to log in again. To prevent your Mac from falling asleep, you can use the caffeinate command:
We can also set time periods up so the command is only active for a temporary period of time.
To do this, add the -t flag followed by the number of seconds you want the feature to be enabled for:
caffeinate -t 600
The command above will make your Mac not enter the sleep state for 10 minutes (600 seconds). It can be stopped before then by pressing ctrl + c.

Mac allows you to set a custom login message. You can write a motivational quote, or if you want to convey some message to someone using your computer, then this is a great choice. I added my address and mobile number on the login screen, so even if I lose my Mac, it would be easy for the person who found it to contact me.
sudo write /Library/Preferences/com.apple.loginwindow LoginwindowText "Custom Text Here"
This will ask for your administrative password. That’s it. For more detailed info, refer to this page.
