-Prevent Your Mac from Sleeping

Your computer goes to sleep so that it doesn't waste resources and power working when you're not using it, but sometimes you need to temporarily keep it awake while you're doing a certain task. To do this, just enter this command into Terminal: caffeinate -t 3600 That will keep you Mac awake for an hour. The 3600 comes from how many seconds are in an hour, so just change that number to however long you want to keep your computer awake for.
