Like ourselves, a Mac needs to sleep. It’s a machine that needs to recharge. But there are times when you need it operating in wake mode. Either it’s processing something and can't shut down, or you are watching a movie or TV series and don't want to have to wake it up after a perceived period of inactivity.
Here are the steps you should take for keeping a Mac awake:
- Go to the Apple menu in the top toolbar > System Preferences
- Click on Energy Saver;
- Now you have a wide range of options for controlling sleeping and waking times and cycles:
- Use the slider to determine when exactly a Mac goes to sleep after a period of inactivity;
- You can even keep it awake indefinitely, although that isn't recommended for long periods of time;
- Another setting can be ticked or unticked to “Put hard disks to sleep when possible”;
- Also a useful setting for those needing to keep a Mac awake for a while: “Prevent computer from sleeping automatically when the display is off”;
- If you need others to access your Mac, the following is a useful setting: “Wake for network access.”
There are a number of third-party apps that give you a range of features beyond what is built-into macOS. Some of them are worth downloading and taking for a spin. Another app that can solve problems with a Mac’s sleep and waking cycle is CleanMyMac X.
