To enable Power Nap:
- Open “System Preferences.”
- Navigate to “Energy Saver.”
- Check the box for “Enable Power Nap while on battery power.”
This will not directly prevent sleep, but it will ensure some activities continue even when your Mac appears to be asleep.
Using a Presentation Mode
If you’re using your Mac for presentations, activating a presentation mode will also keep your laptop awake.
Enabling Presentation Mode
- Go to “System Preferences.”
- Click on “Displays.”
- Select the “Display” tab.
- Under “Rotation,” select “Disable Sleep.”
This setting is not standard for all displays but can directly ensure that your Mac remains awake during your presentation.
Final Adjustments and Other Considerations
When dealing with preventing sleep modes on your Mac, there are some final steps and considerations to keep in mind.
Accessibility Settings
Sometimes, your Mac’s accessibility settings can influence sleep behavior. Check these by navigating to:
