I recently upgraded from a March 2011 15" MacBook Pro to a 2014 15" MacBook Pro Retina and was disappointed that the wake from sleep is much slower on the new computer.

Is there a way to speed this up?

Note, this is not from standby mode per Is a 3-5 second delay normal for a Retina MacBook Pro to wake up from sleep?

The problem can be replicated as follows:

  1. wait in front of the computer
  2. screen goes blank
  3. immediately press a key
  4. screen stays blank for 1-2 seconds then wakes.

Note, this delay happens if I wake from sleep after hours of sleep, too. In my old MacBook Pro the screen powered on immediately on pressing a key to wake from sleep and if I was waking from sleep by opening the laptop lid the screen was on before the lid was open.

I have Yosemite 10.10.1, the old MacBook had Mavericks.

Any ideas?

  • It would be interesting to know what is it doing before the WindowServer kicks in (display on) in your console.

Maybe the excerpt below can explain.

The full article can be found on OS X Daily, Is Your Mac Slow to Wake from Sleep? Try this pmset Workaround:

If your MacBook Pro or MacBook Air feels slow to wake from sleep after it’s been sleeping for a while, there may be a fairly simple cause: standby mode. Standby mode allows a Mac to potentially have up to 30 days of ‘standby’ time, meaning it can sit in a prolonged sleep state for that long before draining the battery. Basically, standby (and sleep) works by dumping everything out of active RAM into a sleep image file on the hard drive, and then when the Mac wakes from sleep that sleep image file is copied back from the hard drive to RAM. You may have guessed this already, but the reason some Macs take a long time to wake from sleep is that process of copying contents of sleepimage back into memory, and typically the more RAM you have in a Mac the slower the process can be. As you can imagine, it can take a while to copy 8GB or 16GB of data anywhere, even when a Mac has a super fast SSD drive it’s reading from.
