Allow Windows Updates While Your Mac is Sleeping

Parallels Desktop supports OS X Power nap, which lets you keep aspects of Windows up-to-date even while your Mac is sleeping. When Power Nap is enabled, services that usually update information after Windows wakes from sleep (for example, new emails in email applications and new event updates in Calendar) will update while your Mac is in sleep.

To use Power Nap, your computer must be compatible. See Apple.com for more information.

To enable Power Nap:

1. On your Mac, choose Apple menu > System Preferences and click Energy Saver .
2. Depending on whether your Mac is working on batteries or is plugged, make sure Enable Power Nap while on battery power or Enable Power Nap while plugged into a power adapter is selected.

Note: To learn more about Power Nap, please refer to the OS X help resources.
