I’ve been enjoying working with my Macbook Pro Retina since the beginning of 2013
when I returned from Antarctica. Editing HD video from the expedition was not possible on my 2005 vintage Macbook Pro. It just was not happening.
One thing I noticed is that my machine waked up instantly from sleep and is ready to go for logging in. However, if I let it sleep for a couple of hours, it seems like the machine takes forever to come up. And with a built-in solid state drive (SSD), forever equates to about 12-15 seconds. On my old machines, especially the PC, waking up from a deep sleep equated to a minute or more – a serious time waster for a power user.
After some surfing around, I found that the machine goes into what’s essentially a hibernation mode that can maintain the machine for up to 30 days on a fully charged battery. That’s pretty cool but I use my machine daily. So I want the fastest performance possible.
Here are the instructions on how to make your Macbook Pro Retina wake up from sleep rather than standby:
Here’s how to do it on your MacBook.
First bring up Terminal by going to Spotlight and typing Terminal.
Then, run the following pmset command with the -g flag (in Terminal) to see what your current sleep time is (in seconds):
pmset -g |grep standbydelay
Terminal will then display the time in seconds before the Macbook Pro enters standby. Note the value if you want to reset it to factory default. In my case, my machine was at 4200 seconds or 70 minutes.
To change the standby delay from 1 hour to 24 hours, type this command in the terminal window:
sudo pmset -a standbydelay 86400
This will get you to a 24 hour sleep (86400 seconds) before standby. Note that you will need to enter your administrator password when doing this. Also, be careful to type the instructions above exactly. When you do a “sudo” operation, you are running as a system administrator and, though the machine warns you of this:
WARNING: Improper use of the sudo command could lead to data loss or the deletion of important system files. Please double-check your typing when using sudo. Type “man sudo” for more information.
To proceed, enter your password, or type Ctrl-C to abort.
you are now in ultimate command of your machine. It’s not a big deal, just don’t make a typo.
Now my machine always wakes up and is ready to go in 2 seconds.
