If you’re comfortable using Terminal and prefer a more advanced approach, you can modify your Mac’s sleep settings using specific commands. Here’s how:

1. Open Terminal by going to Applications > Utilities > Terminal or by using the Spotlight search (CMD + Space) to search for "Terminal."
2. In the Terminal window, type the following command and press Enter: sudo pmset -a sleep 0
3. You will be prompted to enter your administrator password. Type it in and press Enter.
4. Terminal will execute the command to set the sleep time to 0, effectively disabling sleep mode on your Mac.
5. If you want to revert back to the default sleep settings, use the command sudo pmset -a sleep 1.
6. Close the Terminal window when you’re done.
