Macbook pro is slow to wake up after sleep

Genius! Thanks. I am giving this a try. 😎

I have this problem as well with my new rMBP. It's not likely to be due to standby, as the machine takes ~10 seconds to wake after closing and re-opening the lid.

please see here for an issue with standby mode:

I think I have stopped this happening on my MBP Retina by turning off Power Nap. After every slow wake up I noticed my Time Machine disk (in a Time Capsule) mounted on the desktop. Quick awakenings - no TM disk mounted. I assumed it was due to TM backups being underway while I was trying to wake it up.

So I fixed the slow startup when my laptop goes to sleep. I changed the hybernate mode in Terminal. My setting was 25. I changed it to 3 but also could have done 0.

Check to see what your setting is: pmset -g | grep hibernatemode

To change the setting: sudo pmset -a hibernatemode X

Make sure X is either 0, 3, or 25.

Here is the explanation on what each number is:

hibernatemode = 0 (binary 0000) by default on supported desktops.

The system will not back memory up to persistent storage.

The system must wake from the contents of memory; the system will lose context on power loss.

This is, historically, plain old sleep. 

hibernatemode = 3 (binary 0011) by default on supported portables.

The system will store a copy of mem-ory memory ory to persistent storage

(the disk), and will power memory during sleep. The system will wake from memory,

unless a power loss forces it to restore from disk image. 

hibernatemode = 25 (binary 0001 1001) is only settable via pmset.

The system will store a copy of mem-ory memory ory to persistent storage

(the disk), and will remove power to memory. The system will restore from

disk image. If you want "hibernation" - slower sleeps, slower wakes, and

better battery life, you should use this setting.

The Dubs:

Good information to know. I just checked mine with your command "pmset -g | grep hibernatemode" and it's set to 3, but I still get the slow wake after 1 hour.

I changed the standby delay for my machine from 1 hour to be 24 hours by running this command from a terminal window (86400 seconds = 24 hours):

sudo pmset -a standbydelay 86400

So I found this thread after experiencing the issue - my setting is already '3' however ...

>>It takes longer to wake from sleep than it does to start up

Nice one Apple 😐

I agree, same problem with my MacBook. Have had MB's since 2005 and never had this problem before; it seems to be within the last 4-5 months?
