As you know these portable devices are fabulous, they are super thin, powerful and aesthetically beautiful, but have you ever opened your MacBook Retina and observed the display stand there like a limbo for a few seconds before returning to operational?Definitely yes, and it's frustrating to see the box for the password but can not type anything until the MacBook "wakes up" completely.
Apple has included in MacBook Pro and MacBook Air in 2010 after a feature called "standby mode" and it seems that this is precisely the reason that makes the latest MacBook sometimes employ a bit 'longer to return to operate. The good thing is that it seems to be just a simple command entered via the terminal in OS X to access and correct the problem.
Erv Walter was bored by the problem described above, then did some research and later posted on his blog a little guide to remedy the problem.
First, however, we see how the standby mode.
Walter discovered that the screen is "frozen" because what initially appears is a screenshot of the display acquired immediately before entering the "sleep" mode. This is also the reason why the box for entering the password is static and the time is not right that wrong. Usually a new MacBook with SSD takes about 8-10 seconds to be fully operational. This time is necessary for the MacBook exit the standby mode.
The Retina MacBook Pro and MacBook Air usually go into standby mode after being left in "sleep" mode for an hour, and that's because Apple has set them in this way. The purpose of the standby mode is to leave the battery in the MacBook in a sort of limbo for up to 30 days without having to connect your computer to the mains. To enter standby mode it is necessary that you are using the laptop on battery, and they are connected to it USB / Bluetooth, SD card and external displays.
Walter adds: " Note that if the laptop is in sleep mode for less than an hour, then it will turn back almost instantly. I myself have had ... and this is the key to my solution to the problem. It 'emerged, in fact, that this time is configurable. "
Here, then, how to change it.
To customize this time all you have to do is open terminal, copy and paste the following string:
sudo pmset-a standbydelay 86400
The number that is found at the end in seconds, and is equivalent to 24 hours. You can set any value you like. The following command shows you your current configuration:
pmset-g
Increasing this time there should be no major problems with the battery life. If you recharge your MacBook every day, then you should not need more than 24 hours. The best thing to do is make some tests in order to find the time that best suits your needs and then schedule it.
