So I’m a little late with my tip due to me being productively slacking. How can I be productively slacking you may wonder? I’ve actually been learning some new topics such as Angular.js, node.js, git and various others. So without further ado I present to you a tip on Keep Your Mac Healthy with Power Naps.
This tip was taken from the Apple Pro Training Series: OS X Support Essentials 10.9: Supporting and Troubleshooting OS X Mavericks by Kevin M. White and Gordon Davisson
Mac systems introduced after mid-2011 that feature all flash storage, such as MacBook Air models, gained new sleep functionality in OS X Mountain Lion with Power Nap. This feature allows your Mac to wake from sleep occasionally in a low-power mode known as “dark wake” (because the display doesn’t power up), and perform essential background tasks. Many built-in OS X applications and services can work in Power Nap, including Mail, Contacts, Calendar, Reminders, Notes, documents in iCloud, Photo Stream, Mac App Store updates, Time Machine backup, Find My Mac updates, VPN on demand, and MDM configuration profile updates. Note: Power Nap updates only applications that are running when sleep is initiated. If a user logs out of the system prior to sleeping, his or her items don’t update.
For Mac systems that support it, Power Nap is enabled by default for times when your Mac is connected to a power adapter. You can verify or adjust this setting from the Energy Saver settings. You can also enable Power Nap for times when your Mac is running from battery power, although this setting obviously reduces the Mac computer’s battery faster than normal system sleep.
When a Mac is put to sleep with Power Nap enabled, it first waits 30 minutes before dark-waking to check for updates. After that, it dark-wakes every hour to check for updates. You can verify that Power Nap is in effect by checking its log file via the Console. The Power Nap log file is located at /var/log/zzz.log. Note: Some Mac systems require firmware updates to support Power Nap. You can find out more about Power Nap and any required updates from Apple Support article HT5394, “OS X: About Power Nap.”
