How To: Fix MacBook Wake from Sleep Issue
If you open the lid of a 2011 MacBook Air, boom, it wakes up. The newer MacBooks? Not so much. However, here is a quick and easy way to fix the MacBook wake from sleep issue.
The issue at hand is that Apple has reduced the time newer MacBooks stay in Standby Mode, which increases battery life. Though there isn’t a System Preference Pane for this setting, there is a Terminal command that will allow your MacBook to wake quickly from sleep.
That said, if you would like to know what your MacBook’s current Standby setting is, run this command:
To change your Mac’s standby delay from one hour to, for example, 24 hours, open Terminal and type or paste this command and hit Return:
sudo pmset -a standbydelay 86400
86400 seconds = 24 hours
