MacBook Pro Retina Going to Sleep on Battery in Mavericks

by on Dec.30, 2013, under Home, How-To Guides, IT Issues

I recently got myself a MacBook Pro 15″ Retina and noticed that in Mavericks they have removed the option to have separate timers for display sleep and computer sleep.  You can turn off sleep mode  when you’re running on AC power, but not when you’re running on the battery.

The problem with this is that I want the display to turn off to save battery power, but I want all my background processes (eg. Adium/Colloquy) to continue running and for it to stay connected to wifi, but when the display goes blank, it goes straight to sleep and disconnects everything!

The fix for this is to manually set the options via pmset in the terminal. To do this, you’ll need to do the following:
1.    Open Terminal (it’s in the Utilities folder under Applications)
2.    Enter the command:  sudo pmset -b sleep 0
3.    Enter the command:  sudo pmset -b standby 0

You will need to enter your password after running these commands (if it asks for it).
For more information about what this command does, check here:  https://developer.apple.com/library/mac/documentation/Darwin/Reference/ManPages/man1/pmset.1.html

Hope this helps someone :)
